After extended monitoring, Exclaimer can confirm that the Add-in is now appearing within Outlook and Outlook on the Web as expected for our customers.

The cause of the Add-in not appearing within Outlook looks to have been due to an issue within the AppSource deployment system provided by Microsoft that the Exclaimer Add-in is recommended to be deployed through. We also note that other service providers reported issues with Add-ins not appearing as expected for end users within Microsoft 365.

If you are continuing to experience issues with your Add-in, please reach out to our Support team for assistance.
