Office 365 users in teams meeting show as guest
During a team video meeting (a class), I saw that most of our students (who all log in with their office 365 accounts) show up as "guests". This happened to me last week (but fixed itself), and today happened to another teacher (although I can see everyone with their username or display name, she only sees 'guest'). Even after she logged out and back in again, when joining the video meeting she only sees the list of attendees and chat with almost everyone as 'guest' (a few students show with their username or display name). Does anyone know what is happening?
