Microsoft Teams desktop app- Error 503 + web and mobile not working
Anyone else experience Teams being down on all three > desktop/web/mobile? We are in the UK.
Tanya Denton Yes, UK as well, but it only seems to be on fresh sign-ins. If the user is already in Teams and signed in, they seem to be OK.
Scott Wichall That makes sense as the update we have just received says:
Root cause: An authentication certificate has expired causing users who have logged out and those that are still logged in to have issue using the service.
Tanya Denton That explains it then. What it doesn't resolve is that I have spent the last 30 mins trying to get a fresh build laptop userprofile setup, and failing to get Teams logged in LOL.
