Hey together,

 

me and some of my colleagues are using MS Teams with a guest access of one our partners. Since the beginning of this week we can neither log-in via Web nor via App. The app always shows the error code "caa30193". When I try logging in via Web, I receive Error 403 (Forbidden). 
Partner already tried removing us from the chat and adding us again, but we still cannot log-in. 

Can anybody tell me where the source for this error message lies and how to fix it?

Best regards,

Malik
