Hi @Coates-Eveleigh, Martha
I’m sorry to hear about this experience. I can understand how frustrating it must have been when you were unable to start a meeting due to an account mix-up.
To help avoid this type of issue in the future, you may want to sign out of Teams completely and then sign back in using only your work account before joining or starting work-related meetings. When both a personal Microsoft account and a work account are signed in, it can sometimes be difficult to determine which account is being used for scheduling or managing a meeting.
You could also verify which account is shown in the Teams profile menu before creating or starting a meeting to ensure it matches the account that owns the meeting invitation.
I hope this helps prevent similar issues going forward.
