Teams log in issues with non-MS eMAIL

Andor J Kiss 21 Reputation points


Two problems:

  1. I'm having issues signing into Microsoft Teams (Linux) using my name@Stuff .com address - is this because it's a google eMAIL, or is there another issue?
  2. How do I switch between two different project accounts? (two different eMAIL sign-ins)?


Here's the sign-in error: User account '########@Stuff .com' from identity provider '' does not exist in tenant '###########' and cannot access the application '5e3ce6c0-2b1f-4285-8d4b-75ee78787346'(Microsoft Teams Web Client) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

    According the sign-in error information, you need to add this xxx@Stuff .com as an external users in your tenant.
