I'm trying to set up a team that can be accessed by external users as well. Guest users is switched on and some external users are able to join the team but others are being returned with the error "unknown_email_address@invalid.teams.ms". Is there something I've missed?

    When a user is disabled in Azure AD or blocked, the user will continue to appear in Microsoft 365 applications. The account needs to be deleted in order for it to disappear from applications.

    There is also a known issue that causes disabled users in Team's due to caching. If the user still shows, you can clear the Team's cache for the affected users (%appdata%\Microsoft\Teams), and it should disappear.
