Title: Some users’ new meetings created in the Outlook desktop client may automatically include Microsoft Teams meetings

User impact: 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 versions 1.0.23125 and above.

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 we’re working to remediate this impact, affected users can create non-Microsoft 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.

Current status: We’ve resolved the deployment scheduling issue and the fix deployment is approximately 25 percent saturated. Some users will begin to see relief as the fix propagates throughout the environment. We anticipate the deployment to be complete and the issue will be remediated for all users by our next scheduled update.

Scope of impact: Users leveraging the Microsoft Teams meeting add-in for the Outlook desktop client build versions 1.0.23125 and above 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.
