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 be able to avoid impact by utilizing the Microsoft Teams classic 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: Our updated deployment timelines continue to estimate that our solution will have completed by Thursday, April 25, 2024. We’re expecting to confirm that impact has been remediated by our next scheduled update.
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.
