Custom form script is now disabled by default
Last updated: Oct 13, 2017
ISSUE
Custom form script is now disabled by default and requires setting registry keys to re-enable it.
The new registry key has a default value of 1, which indicates form script should not run.
First create this key:
32 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookSecurity
32 bit Office on 32 bit Windows or 64 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0OutlookSecurity
Then create DWORD (32-bit) Value 0 and set the name to DisableCustomFormItemScript to enable custom form scripts.
Once custom form scripts have been enabled at all, they must then be enabled per form message class. For instance, if you have a form with the message class IPM.Note.Custom, we must register “IPM.Note.Custom” as a trusted form message class. To do this, first create this key:
32 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookFormsTrustedFormScriptList
32 bit Office on 32 bit Windows or 64 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0OutlookFormsTrustedFormScriptList
Then, create REG_SZ values in this key for each form you wish to allow scripts to run. In the above example, you would create a REG_SZ value named “IPM.Note.Custom” with empty data.
When designing a form, Run This Form will run a form using the message class of the base form. So if you started designing an IPM.Note form and want to Run This Form, you will need to have IPM.Note registered. After you publish, the published message class is what will be checked. Once you have finished designing your form and published it to a custom form name, remove the standard “IPM.Note” from the trusted list.
Notes:
You need to restart Outlook after setting the TrustedFormScriptList key.
The example registry keys use 16.0 for Outlook 2016. Use 15.0 for Outlook 2013, 14.0 for Outlook 2010 and 12.0 for Outlook 2007.
After making the above changes the registry keys will look like the following:
[HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookSecurity]
DisableCustomFormItemScript'=dword:00000000
[HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookFormsTrustedFormScriptList]
'IPM.Note.Custom'='
'IPM.Note'='
NOTE: In some cases forms in secondary mailboxes and Public folders still don't work after the registry key settings. To fix this, enable scripts in the Trust Center:
Click File > Options. Then select Trust Center > Trust Center Settings > Email Security.
Under the Script in Folders section, click the checkbox for Allow script in shared folders and Allow script in Public folders and click OK and OK again to close out the windows.
STATUS
The change was first introduced in the September 12th, 2017 Outlook Public Updates and is included in the following MSI updates which now require the registry keys.
Click to Run status is as follows:
Monthly Channel (Current Channel) will start supporting the registry keys in the update scheduled for September 18th release build 16.0.8431.2079.
Semi-Annual Channel (FRDC) supports the registry keys with build 16.0.8431.2079.
Deferred Channel supports the registry keys with build 16.0.8201.2193.
Deferred Extended status is TBD.
Insider Fast status is TBD.
Insider Slow supports the registry keys with build 16.0.8431.2079.
Can't open Enterprise Vault items
Last Updated: October 13, 2017
ISSUE

STATUS: WORKAROUND
Please follow the steps provided in Issue #2: Custom form script is now disabled by default which is just above this issue.
Important Announcement about Outlook.com
Reconnect Outlook 2016 or Outlook 2013 to Outlook.com for uninterrupted email access
ACTION REQUIRED: Reconnect Outlook 2016 or Outlook 2013 to Outlook.com for uninterrupted email access | ||
|---|---|---|
Earlier this year we introduced the new Outlook.com, which helps you focus on what matters, collaborate effortlessly, and get more done. As part of the upgrade, we are also moving accounts to a more secure and reliable infrastructure. The upgrade impacts all Outlook, Hotmail, Live, or MSN email accounts. Once your Outlook.com account has been upgraded, you’ll need to reconnect Outlook 2016 or Outlook 2013 to your Outlook.com account to ensure the best experience and fix issues. To check if your account has been upgraded, login to your account through a web browser and compare your mailbox with the images below.
If you do not reconnect your upgraded email account, you will soon no longer be able to send or receive Outlook.com emails via your desktop version of Outlook 2016 and 2013 until you reconnect. Additionally, by not reconnecting, you may experience email and calendar sync issues that will be resolved once you reconnect. You will still be able to send and receive emails via the web on www.Outlook.com. For detailed instructions and help on how to reconnect your account, please visit this article. Note: This change only affects any Outlook.com accounts you are accessing via Outlook 2016 or Outlook 2013. You do not need to reconnect to your other email accounts, such as Office 365, Exchange, or other third party email accounts. You can also continue to send, receive, and access email from your Outlook.com account on the web via any popular web browser. |
Outlook issues after connecting Outlook to Outlook.com
Outlook.com email account appears as 'outlook_[long series of letters and numbers]@outlook.com' in Outlook for Windows [WORKAROUND]
ISSUE
After connecting to Outlook for Windows (Outlook 2016, 2013, 2010 versions) to your Outlook.com email account, your may experience the following:
Your email account name shows up as outlook_[long series of letters and numbers]@outlook.com in the Folder Pane and when composing emails using Outlook for Windows.
Recipients will also receive the email from the sender with the outlook_[long series of letters and numbers]@outlook.com format.
When recipients reply to the email, the email bounces and you may receive the message “Undeliverable message when you send Internet mail in Outlook.”
This issue only impacts customers using Outlook for Windows. Emails sent via Outlook.com on the web works correctly and emails will be sent with the correct email address.
STATUS
The Outlook client does not currently support using a non Microsoft domain primary alias. For the time being to get the account to work in Outlook you need to change the primary alias to a Microsoft domain account, such as @outlook.com or @hotmail.com. The Outlook Team is doing work that will enable some supported use of aliases in the near future. We will update this topic as soon as the functionality is available.
WORKAROUND
This issue occurs for users with multiple account aliases. We are actively working on a fix. In the meantime, to fix this issue, please do the following:
Note: If you do not have another alias, click the link on the page to create one 'Click Add email and a new alias'. Then choose the option 'Create a new email address and add it as an alias'
Go to https://account.live.com/names/Manage and sign in to your Outlook.com account.
Set your Outlook.com email as the primary alias.
In Outlook for Windows, remove and re-add the account. See the steps in this article: Add your Outlook.com account in Outlook for Windows
Sending an email from an Outlook.com connected account, Outlook sends the email as 'On behalf of' your Outlook.com account [WORKAROUND]
Last updated: February 8, 2017
ISSUE
If Outlook is connected to a primary Outlook.com account that is also connected to other secondary non-Microsoft accounts (such as Gmail, Yahoo, etc.), when sending an email in Outlook, you are not able to choose the other secondary connected account as the 'From' sending account.
If you manually type in the secondary connected account email address in the 'From' field, the email is sent as 'On behalf of' your primary Outlook.com account.
STATUS: WORKAROUND
Outlook supports sending from a secondary connected account for Microsoft owned domains such as @outlook.com, @live.com, @hotmail.com but has not implemented this functionality for third-party domains.
The Outlook team is listening to your feedback and investigating adding this functionality to future updates. Please vote up the request and add any feedback on UserVoice: Option to make Microsoft Outlook 2016 work with Outlook.com connected. In the meantime, please use the following workaround:
WORKAROUND
You can also add the secondary connected accounts (Gmail, Yahoo, etc.) in Outlook.com as additional accounts in the Outlook profile.
In Outlook, choose the File tab.
Under Account Information, choose Add Account.
On the Auto Account Setup page, enter your name, email address, and password, and then choose Next.
Note: If you receive an error message after choosing Next, double check your email address and password. If both are correct, see the next section.
Choose Finish.

Unable to configure Custom Domains accounts to connect in Outlook as an Exchange account [WORKAROUND]
Last updated: January 24, 2017
ISSUE
When connecting in Outlook as an Exchange account, you are unable to configure your personal custom domain email account.
WORKAROUND
Add a CNAME record to your DNS settings at your domain registrar. A CNAME record is needed for Outlook to configure the account using Autodiscover. The only record you need to add is for Host Autodiscover.

Verify your MX record is still configured for Hotmail. An MX record ensures you can receive email from other people.
When you originally setup your Domain settings for Outlook.com an MX record was added to your DNS settings. This record has some unique numbers and/or letters followed by *.pamx1.hotmail.com and it needs to be preserved. You can confirm the MX record is still configured properly by looking up your domain at https://mxtoolbox.com. This record should be listed before any other MX records for this domain. For example, this is what it should look like on https://mxtoolbox.com:

'Something went wrong..' or 'Search results may be incomplete' error when searching in Outlook [FIXED]
ISSUE
Last updated: August 3, 2017
This issue affects all Outlook versions on Windows 7, Windows 8, Windows 10.
When searching in Outlook, you get this error: “Something went wrong and your search couldn’t be completed.”, or 'Search results may be incomplete because items are still being indexed'.
And you'll see this Event Log warning:
STATUS: FIXED
Windows has released fixes via Windows Updates to address a reliability issue in Windows Search. Below are the relevant KB updates for each version:
Note:The fix for this issue has been released on June 27, 2017. If you implemented the workaround to disable Windows Desktop Search Service, you can now set the PreventIndexingOutlook registry key to DWORD: 0 to go back to using Windows Search.
WORKAROUND
If the issue is not resolved after installing the updates, please use the workaround below:
If search is not working for Exchange accounts, delete the OST files which will cause a re-sync and re-index of the account:
OST files are typically stored at C:Users<your username>AppDataLocalMicrosoftOutlook.
To find the name and location of the OST file, click File, Account Settings, Account Settings, Data Files. Locate the correct email address, click on the name, and click Open File Location.
Before you can delete the OST file, you need to close Outlook so the process will release the file.
After deleting the file, restart Outlook and let the email sync again.
Another workaround is to Create a new Outlook profile, and add your accounts to the new profile. We recommend keeping the old profile until you know you have moved over any local data or PST files.
Until you can install the Windows Update fix release, you can set a registry key that will cause Outlook to stop using the local Windows Search service. When this registry key is set, Outlook will use its own built-in search engine. The built-in search will display the message below to indicate it is not using the Windows Search service.
Disable Windows Desktop Search Service for Outlook:
Note: The following steps show you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Please make sure that you follow these steps carefully.

Vulnerability information (applies to all versions)
MAPI does not validate that a provider’s DLL that it is requested to load is registered correctly in MapiSVC.inf or even that it comes from the local machine. This can be exploited by creating a file together with an OLE object in such a way to cause MAPI to load a DLL from a network share when the OLE object is activated. This can allow arbitrary code execution to occur.

All Mail and Unread Mail tab options no longer show in Outlook [WORKAROUND]
Last updated: June, 5 2017
ISSUE
You may notice that All, Unread , Mentioned and other sort and filtering options, such as By date, and Newest are missing in Outlook above your email list.
If your Outlook version is 1703 (Build 7967.2161) or higher, the filters and sort options were moved under the All drop down menu, to accommodate space for the new Focused inbox.
Note: If you don't know your Outlook version, go to File > Office Account to check your Outlook version.
How to filter and sort your mail
To sort your emails by Unread, Mentioned or use other filters, select the All button and choose one of the options. You can also select Arrange By and then pick one of the options such as Date, From, etc.
Another options is to use the Filter Email button on the ribbon. For more information, see Filter email messages.
Note that you can quickly tell how your mail is currently sorted, by the presence of a small triangle on the field headers.
Use the Quick Access Toolbar
To access the filtering options faster, add them to your Quick Access Toolbar.
For example, to add Unread to the Quick Access Toolbar:
Click anywhere in the Search box.
When the Search tab commands become available on the toolbar, right-click the Unread icon, and then select Add to Quick Access Toolbar.
To add Arrange by to your Quick Access Toolbar, you need to add it to the ribbon first:
Right click the Ribbon and click Customize the Ribbon.
Under the Customize the Ribbon Main Tabs , click the Home (Mail) > New Group.
Select Rename, and rename the new group to Arrange.
In the Choose commands from column, select All Commands.
Scroll down to Arrange By, select the third Arrange By and click Add.
Click the name of the new group (Arrange By) under Customize the Ribbon, and click the UP arrow to move it under the Respond group. You can change this later if you want to move it somewhere else.
Click OK. This will add the new group on the Ribbon.
To add Arrange by to your Quick Access Toolbar, right click on the new Arrange By button and click Add to Quick Access Toolbar.
For more information, see Add a command to the Quick Access Toolbar

Custom form script is now disabled by default
Last updated: Oct 13, 2017
ISSUE
Custom form script is now disabled by default and requires setting registry keys to re-enable it.
The new registry key has a default value of 1, which indicates form script should not run.
First create this key:
32 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookSecurity
32 bit Office on 32 bit Windows or 64 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0OutlookSecurity
Then create DWORD (32-bit) Value 0 and set the name to DisableCustomFormItemScript to enable custom form scripts.
Once custom form scripts have been enabled at all, they must then be enabled per form message class. For instance, if you have a form with the message class IPM.Note.Custom, we must register “IPM.Note.Custom” as a trusted form message class. To do this, first create this key:
32 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookFormsTrustedFormScriptList
32 bit Office on 32 bit Windows or 64 bit Office on 64 bit Windows
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0OutlookFormsTrustedFormScriptList
Then, create REG_SZ values in this key for each form you wish to allow scripts to run. In the above example, you would create a REG_SZ value named “IPM.Note.Custom” with empty data.
When designing a form, Run This Form will run a form using the message class of the base form. So if you started designing an IPM.Note form and want to Run This Form, you will need to have IPM.Note registered. After you publish, the published message class is what will be checked. Once you have finished designing your form and published it to a custom form name, remove the standard “IPM.Note” from the trusted list.
Notes:
You need to restart Outlook after setting the TrustedFormScriptList key.
The example registry keys use 16.0 for Outlook 2016. Use 15.0 for Outlook 2013, 14.0 for Outlook 2010 and 12.0 for Outlook 2007.
After making the above changes the registry keys will look like the following:
[HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookSecurity]
DisableCustomFormItemScript'=dword:00000000
[HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0OutlookFormsTrustedFormScriptList]
'IPM.Note.Custom'='
'IPM.Note'='
NOTE: In some cases forms in secondary mailboxes and Public folders still don't work after the registry key settings. To fix this, enable scripts in the Trust Center:
Click File > Options. Then select Trust Center > Trust Center Settings > Email Security.
Under the Script in Folders section, click the checkbox for Allow script in shared folders and Allow script in Public folders and click OK and OK again to close out the windows.
STATUS
The change was first introduced in the September 12th, 2017 Outlook Public Updates and is included in the following MSI updates which now require the registry keys.
Click to Run status is as follows:
Monthly Channel (Current Channel) will start supporting the registry keys in the update scheduled for September 18th release build 16.0.8431.2079.
Semi-Annual Channel (FRDC) supports the registry keys with build 16.0.8431.2079.
Deferred Channel supports the registry keys with build 16.0.8201.2193.
Deferred Extended status is TBD.
Insider Fast status is TBD.
Insider Slow supports the registry keys with build 16.0.8431.2079.

ACTION REQUIRED: Reconnect Outlook 2016 or Outlook 2013 to Outlook.com for uninterrupted email access | ||
|---|---|---|
Earlier this year we introduced the new Outlook.com, which helps you focus on what matters, collaborate effortlessly, and get more done. As part of the upgrade, we are also moving accounts to a more secure and reliable infrastructure. The upgrade impacts all Outlook, Hotmail, Live, or MSN email accounts. Once your Outlook.com account has been upgraded, you’ll need to reconnect Outlook 2016 or Outlook 2013 to your Outlook.com account to ensure the best experience and fix issues. To check if your account has been upgraded, login to your account through a web browser and compare your mailbox with the images below.
If you do not reconnect your upgraded email account, you will soon no longer be able to send or receive Outlook.com emails via your desktop version of Outlook 2016 and 2013 until you reconnect. Additionally, by not reconnecting, you may experience email and calendar sync issues that will be resolved once you reconnect. You will still be able to send and receive emails via the web on www.Outlook.com. For detailed instructions and help on how to reconnect your account, please visit this article. Note: This change only affects any Outlook.com accounts you are accessing via Outlook 2016 or Outlook 2013. You do not need to reconnect to your other email accounts, such as Office 365, Exchange, or other third party email accounts. You can also continue to send, receive, and access email from your Outlook.com account on the web via any popular web browser. |
Outlook issues after connecting Outlook to Outlook.com
Outlook.com email account appears as 'outlook_[long series of letters and numbers]@outlook.com' in Outlook for Windows [WORKAROUND]
ISSUE
After connecting to Outlook for Windows (Outlook 2016, 2013, 2010 versions) to your Outlook.com email account, your may experience the following:
Your email account name shows up as outlook_[long series of letters and numbers]@outlook.com in the Folder Pane and when composing emails using Outlook for Windows.
Recipients will also receive the email from the sender with the outlook_[long series of letters and numbers]@outlook.com format.
When recipients reply to the email, the email bounces and you may receive the message “Undeliverable message when you send Internet mail in Outlook.”
This issue only impacts customers using Outlook for Windows. Emails sent via Outlook.com on the web works correctly and emails will be sent with the correct email address.
STATUS
The Outlook client does not currently support using a non Microsoft domain primary alias. For the time being to get the account to work in Outlook you need to change the primary alias to a Microsoft domain account, such as @outlook.com or @hotmail.com. The Outlook Team is doing work that will enable some supported use of aliases in the near future. We will update this topic as soon as the functionality is available.
WORKAROUND
This issue occurs for users with multiple account aliases. We are actively working on a fix. In the meantime, to fix this issue, please do the following:
Note: If you do not have another alias, click the link on the page to create one 'Click Add email and a new alias'. Then choose the option 'Create a new email address and add it as an alias'
Go to https://account.live.com/names/Manage and sign in to your Outlook.com account.
Set your Outlook.com email as the primary alias.
In Outlook for Windows, remove and re-add the account. See the steps in this article: Add your Outlook.com account in Outlook for Windows
Sending an email from an Outlook.com connected account, Outlook sends the email as 'On behalf of' your Outlook.com account [WORKAROUND]
Last updated: February 8, 2017
ISSUE
If Outlook is connected to a primary Outlook.com account that is also connected to other secondary non-Microsoft accounts (such as Gmail, Yahoo, etc.), when sending an email in Outlook, you are not able to choose the other secondary connected account as the 'From' sending account.
If you manually type in the secondary connected account email address in the 'From' field, the email is sent as 'On behalf of' your primary Outlook.com account.
STATUS: WORKAROUND
Outlook supports sending from a secondary connected account for Microsoft owned domains such as @outlook.com, @live.com, @hotmail.com but has not implemented this functionality for third-party domains.
The Outlook team is listening to your feedback and investigating adding this functionality to future updates. Please vote up the request and add any feedback on UserVoice: Option to make Microsoft Outlook 2016 work with Outlook.com connected. In the meantime, please use the following workaround:
WORKAROUND
You can also add the secondary connected accounts (Gmail, Yahoo, etc.) in Outlook.com as additional accounts in the Outlook profile.
In Outlook, choose the File tab.
Under Account Information, choose Add Account.
On the Auto Account Setup page, enter your name, email address, and password, and then choose Next.
Note: If you receive an error message after choosing Next, double check your email address and password. If both are correct, see the next section.
Choose Finish.

Unable to configure Custom Domains accounts to connect in Outlook as an Exchange account [WORKAROUND]
Last updated: January 24, 2017
ISSUE
When connecting in Outlook as an Exchange account, you are unable to configure your personal custom domain email account.
WORKAROUND
Add a CNAME record to your DNS settings at your domain registrar. A CNAME record is needed for Outlook to configure the account using Autodiscover. The only record you need to add is for Host Autodiscover.
Record type
Host
Points to
TTL
CNAME (Alias)
autodiscover

Verify your MX record is still configured for Hotmail. An MX record ensures you can receive email from other people.
When you originally setup your Domain settings for Outlook.com an MX record was added to your DNS settings. This record has some unique numbers and/or letters followed by *.pamx1.hotmail.com and it needs to be preserved. You can confirm the MX record is still configured properly by looking up your domain at https://mxtoolbox.com. This record should be listed before any other MX records for this domain. For example, this is what it should look like on https://mxtoolbox.com:

Cannot edit the shared Outlook.com calendar in Outlook 2016 [WORKAROUND]
Last updated: May 2, 2017
Currently, you can't use Outlook on Windows to edit calendars that are shared with your Outlook.com account, even if you've reconnected your Outlook.com account to Outlook. We're working to make it possible to edit shared calendars in Outlook 2016 for Windows.
To edit a shared calendar, go online to your own Outlook.com calendar, open Calendar for Windows 10, or use a mobile device. Read how to Add your Outlook.com account to another mail app.
Error when sharing a calendar from Outlook.com personal or home account to an Office 365 business account [WORKAROUND]
Last updated: May 2, 2017
ISSUE
When you try to accept a shared Outlook.com calendar using your Office 365 for business account in Outlook 2016, you might receive the 'Something went wrong' error or your sign-in might fail.
STATUS: WORKAROUND
To access the calendar shared with your Office 365 for business account, you’ll need to accept the invitation from Outlook on the web, iOS, or Android.

VBScript does not run or you receive malicious code warning when using a custom form for Outlook [Fixed]
ISSUE
Last updated: Sep 17, 2017
Note: Please also see this article for an update on this issue: Custom form script is now disabled by default.
This issue affects Outlook 2007, Outlook 2010, Outlook 2013, and Outlook 2016.
When you use a custom form that you have created for Outlook, you see the following two symptoms:
VBScript does not run.
You get a malicious code warning:
STATUS
If you’re an Office 365 customer, the fix is now available to Insider Fast audience.
For other channels, an update is scheduled for mid-September, in versions 16.0.8418.5703 and later. We will update this page when the fix is released.
Issue is fixed for all MSI versions. For Outlook 2007, Outlook 2010, Outlook 2013 and Outlook 2016, install the updates below to fix the issue:
'Something went wrong..' or 'Search results may be incomplete' error when searching in Outlook [FIXED]
ISSUE
Last updated: August 3, 2017
This issue affects all Outlook versions on Windows 7, Windows 8, Windows 10.
When searching in Outlook, you get this error: “Something went wrong and your search couldn’t be completed.”, or 'Search results may be incomplete because items are still being indexed'.
And you'll see this Event Log warning:
STATUS: FIXED
Windows has released fixes via Windows Updates to address a reliability issue in Windows Search. Below are the relevant KB updates for each version:
Note:The fix for this issue has been released on June 27, 2017. If you implemented the workaround to disable Windows Desktop Search Service, you can now set the PreventIndexingOutlook registry key to DWORD: 0 to go back to using Windows Search.
WORKAROUND
If the issue is not resolved after installing the updates, please use the workaround below:
If search is not working for Exchange accounts, delete the OST files which will cause a re-sync and re-index of the account:
OST files are typically stored at C:Users<your username>AppDataLocalMicrosoftOutlook.
To find the name and location of the OST file, click File, Account Settings, Account Settings, Data Files. Locate the correct email address, click on the name, and click Open File Location.
Before you can delete the OST file, you need to close Outlook so the process will release the file.
After deleting the file, restart Outlook and let the email sync again.
Another workaround is to Create a new Outlook profile, and add your accounts to the new profile. We recommend keeping the old profile until you know you have moved over any local data or PST files.
Until you can install the Windows Update fix release, you can set a registry key that will cause Outlook to stop using the local Windows Search service. When this registry key is set, Outlook will use its own built-in search engine. The built-in search will display the message below to indicate it is not using the Windows Search service.
Disable Windows Desktop Search Service for Outlook:
Note: The following steps show you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Please make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see this article.

ISSUE
iCloud fails to load properly in Outlook 2007, Outlook 2010, Outlook 2013 and Outlook 2016.
When accessing Calendar, Contacts, or Tasks, you get the following error:
The set of folders cannot be opened. MAPI was unable to load the information service C:PROGRA~2COMMON~1AppleInternet ServicesAPLZOD.dll. Be sure the service is correctly installed and configured.'
STATUS: WORKAROUND
The loading of unregistered MAPI services has been disabled by default to make Outlook more secure.

For Outlook 2007, use the workaround below:
Warning: This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. Microsoft does not recommend this workaround but is providing this information so that you can choose to implement this workaround at your own discretion. Use this workaround at your own risk.
If you have trusted applications that depend on being loaded in this manner, you can re-enable those applications by setting the following registry key:
REG_DWORD HKEY_CURRENT_USERSoftwareMicrosoftOffice12.0OutlookSecurityAllowUnregisteredMapiServices
You can use the following registry subkey to apply the registry setting as a domain policy:
HKCUSoftwarePoliciesMicrosoftOffice12.0OutlookSecurityAllowUnregisteredMapiServices
Value 0 (default): Block loading of unregistered MAPI services. This is the recommended setting to avoid unexpected execution of unknown code.
Value 1: Enable loading of unregistered MAPI services.
Important: The following steps show you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Please make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see this article.
To make these registry changes, follow these steps:
Click Start, click Run, type regedit in the Open box, and then click OK.
Locate and then click the following subkey in the registry:
HKCUSoftwareMicrosoftOffice12.0OutlookSecurity
On the Edit menu, point to New, and then click DWORD Value.
Type AllowUnregisteredMapiServices for the name of the DWORD, and then press Enter.
Right-click AllowUnregisteredMapiServices, and then click Modify.
In the Value data box, type 1 to enable the registry entry, and then click OK.
Note: To disable the AllowUnregisteredMapiServices setting, type 0 (zero), and then click OK.
Exit Registry Editor, and then restart the computer.
Vulnerability information (applies to all versions)
MAPI does not validate that a provider’s DLL that it is requested to load is registered correctly in MapiSVC.inf or even that it comes from the local machine. This can be exploited by creating a file together with an OLE object in such a way to cause MAPI to load a DLL from a network share when the OLE object is activated. This can allow arbitrary code execution to occur.
