NHSmail Reference : INC37121122
Microsoft Reference : TM649896
Issue Status : RESOLVED
Issue Description : Some users’ new meetings created in the Outlook desktop client may automatically include Microsoft Teams meetings.
More info : Impact is specific to the Microsoft Teams meeting add-in for the Outlook desktop client build version 1.0.23125.
Impact occurs despite users unchecking “Add online meeting to all meetings” in Outlook Calendar settings. Users can also disable the add-in to avoid this issue.
While Microsoft are working to remediate this impact, affected users can create non Teams meetings using the following steps:
1. Access the New Meeting dropdown in the Calendar ribbon of Outlook.
2. Select the New meeting request option in the menu by right clicking on Outlook calendar.
Final Update : 16/08/2023 09:15:00 AM – Microsoft have successfully deployed the fix to all impacted environments, and they’ve verified with affected users that this issue is now resolved.
Scope of impact : Users leveraging the Microsoft Teams meeting add-in for the Outlook desktop client build version 1.0.0-23180.1, and attempting to create new meetings in the Outlook desktop client may be affected.
Root cause : Some recent changes intended to optimize the Microsoft Teams meeting add-in for the Outlook desktop client interacted negatively with the code path leveraged in specific older Outlook desktop versions, subsequently resulting in impact.
Next steps : Microsoft are investigating how the recent changes intended to optimize the Microsoft Teams meeting add-in for the Outlook desktop client interacted negatively with the code path leveraged in specific older Outlook desktop versions, subsequently resulting in impact to prevent this problem from happening again.
