Title: Some users’ Microsoft Teams clients may freeze when attempting to access the Teams menu in the sidebar
User impact: Users’ Microsoft Teams clients may freeze when attempting to access the Teams menu in the sidebar.
More info: Users receive an unexpected error message stating “You don’t have access to this channel. Contact the owner … to get access.” despite having proper permissions. Please note that if users don’t receive this error message, it’s not related to this event and needs to be investigated independently.
This can affect users on both the web and desktop clients running the new Microsoft Teams. While we’re focused on remediation, users may able to avoid impact by utilizing the classic Microsoft Teams experience.
Impacted users may be able to resolve the frozen client issue by proceeding with the following steps:
1. Sign out of Microsoft Teams.
2. Completely close out of the Microsoft Teams client by right-clicking on the system tray and hitting “Quit Teams”, or by closing the browser window.
3. Reopen the Teams client and sign back in.
Current status: We’ve initiated the deployment of our fix and anticipate some users may start seeing relief by our next scheduled update as the fix saturates throughout the affected environment. We expect that deployment will complete by Thursday, April 25, 2024, remediating the issue for all users. We’ll continue to monitor the fix deployment to confirm this timeline remains viable.
Scope of impact: Some users attempting to access the Teams menu through the sidebar in the new Microsoft Teams web and desktop clients may be impacted.
Start time: Tuesday, March 26, 2024, at 5:09 AM UTC
Root cause: A recent service update introduced an issue where users’ default channel information isn’t being called as expected in the new Microsoft Teams, resulting in impact.
