When I sign in to use Teams, I use an account named "******@mydomain.com". I use the Microsoft Authenticator to authenticate my identity. The login usually succeeds. I am using the Linux version of Teams. I am not accessing Teams in a browser.
After logging in to Teams, my account is displayed using a different email address, "******@somedomain.com". I do not know from where this other account comes, but I definitely want to remove all reference to it. How do I get rid of that erroneous reference to that account???
I should mention, too, that when someone invites me to a Teams meeting using "******@mydomain.com", the URL I receive never leads me to enter the meeting. I can log in to Teams using that URL, but I never see the meeting to which I have been invited.
