Identified
Microsoft is reporting various issues with Microsoft Teams. Internal testing shows the problems are extremely noticeable on New Teams, but is affecting classic Teams too.
From Microsoft:
Title: Some users may experience multiple issues with their Microsoft Teams
User impact: Users may experience multiple issues with their Microsoft Teams.
More info: Affected scenarios include, but aren't limited to: - Users performing a cold boot may not able to log into teams and will see an "oops" page - Users logging in or unlocking their devices after some time may see missing messages - Users may fail to load messages in channels and chats - Users are unable to view or download their media (images, videos, audio, call recordings, code snippets) - Some messages may experience delays being sent - Call Recordings might take longer to appear in user's OneDrive for Business and SharePoint Online - Users may be unable to load previous Copilot history, or new history is not written - Bots may be unable to download attachments - Sending and receiving read receipt notifications may be delayed
Current status: We’ve identified that a portion of the Microsoft Teams service is experiencing a networking issue. We’re performing a failover to an alternate infrastructure to remediate impact and estimate this should take approximately an hour to complete.
