Current Update: 27/06/2024 08:50:00 AM – Microsoft developed and applied the initial fix to reinstate the necessary data, so additional users won’t be impacted and TMA integration with the Outlook client is functioning for new users. They are analyzing recent changes to identify what’s causing the persisting impact for users who have already been affected by this issue so that they can actively develop and deploy a long-term fix to fully remediate the impact. They will provide an update about the progress and any available estimated time for resolution at their next scheduled communication. While Microsoft are continuing to investigate, affected users can follow the PowerShell script instructions outlined in this documentation to bypass the issue: https://learn.microsoft.com/en-us/microsoftteams/troubleshoot/meetings/teams-meeting-add-in-missing.

Scope of impact: Your organization is affected by this event, and some users’ TMA is missing from the Outlook desktop client.
