How to use Sendent for Outlook Windows-Only instead of Cross-Platform.

In some cases, the Windows-only version of Sendent for Outlook is preferred over its cross-platform counterpart on Windows. You can configure Outlook to offer the Windows-only version to end-users by using a Group Policy Object (GPO). In all instances the Cross-Platform solution will be distributed among the mailbox of the user, however it's supressed on Outlook on Windows. 

Notice: This article is only applicable to the legacy Outlook versions: 2016, 2019, 2021 and 2024 and does not apply to the New Outlook experience.

Ensure the following: 

  1. Sendent for Outlook - Windows Only is present on the client(s).
  2. Sendent for Outlook - Cross-Platform is setup. 
  3. Ensure the GPO administrative template is downloaded and installed.
  4. Retrieve your app id in the manifest.xml file. 

For point 3 see the reference article. 

Follow these steps: 

  1. Open the Local Group Policy Editor (gpedit.msc).

  2. Navigate to User Configuration > Administrative Templates > Microsoft Outlook 2016 > Miscellaneous.

  3. Select the setting Deactivate Outlook web add-ins whose equivalent COM or VSTO add-in is installed.

  4. Open the link to edit the policy setting.

  5. In the dialog Outlook web add-ins to deactivate:

    1. Set Value name to the app id found in the web add-in's manifest.
    2. Set Value to SendentOutlook.
    3. Select OK to put the update into effect.

    The "Outlook web add-ins to deactivate" dialog.(above image is a reference, ensure to replace it with the correct values!)

  6. Push the GPO
  7. Restart Outlook

At this stage, Outlook on Windows will immediately stop displaying the cross-platform version of Sendent for Outlook, and will instead show only the Windows-only version.


You can verify if the GPO was pushed at the client: 

Computer\HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\addins\equivalentcomaddin
