Hi RobertWPB

1.) Do the same as above again
2.) Clear Credential Manager: https://support.microsoft.com/en-gb/help/4026814/windows-accessing-credential-manager
3.) Read this post and follow the steps by Chris Webb: https://techcommunity.microsoft.com/t5/microsoft-teams/can-t-log-into-teams/m-p/304817

Let me know how you get on!

Best, Chris

Thanks again Chris, issue still persist after deleting windows credentials.
I have repeated previous steps followed by your second suggestion and same issue is still ongoing.

  Hmm ok
  
  How about logging into the desktop client on another machine - does that work?
