Microsoft Identifies Issue Preventing Teams Users from Joining Meetings Following Browser Update

Microsoft has identified a recent update to the Microsoft Edge browser as the source of a bug preventing certain users from joining meetings in Microsoft Teams.

According to internal analysis, a regression in the Edge release is responsible for the failure. The regression resulted in issues with authentication and authorization, leading to meeting join failures.

The issue, tracked under TM1288497, affects users who attempt to join scheduled meetings or meetings via links. In the meantime, users experiencing the issue have been advised to restart their Microsoft Teams clients to access meetings.

Workaround and Resolution Status

Restarting Microsoft Teams clients can provide temporary access to meetings, but does not address the underlying problem.
Microsoft is actively investigating the root cause of the issue and working to develop a fix.
The issue is currently classified as an advisory, indicating that it affects a relatively small number of users.
Microsoft is taking the matter seriously and is continuing to analyze diagnostic data and monitor recent service changes to resolve the issue.

Related Issues and Updates

Microsoft has previously addressed similar issues related to the Microsoft Edge update, including a bug that broke right-click paste functionality in chats within the Microsoft Teams desktop client.

A fix for this issue is expected to roll out through the next scheduled platform update, while Microsoft continues to address other ongoing issues, such as Universal Print sharing problems caused by a Microsoft Graph API code change.

In addition, a recent service update that was blocking customers from launching the Microsoft Teams desktop client has been rolled back.
