Hi SauPom
Welcome to Microsoft Q&A forum
To better understand the situation, may I clarify a few more details:
1.When the assistant joins the meeting, are they signed in to Teams with their own account or with the manager’s account (shared credentials / “Add account”)?
2.How do they normally join the meeting?
-Clicking “Join” directly from the manager’s calendar in Outlook
-Clicking “Join” from their own Teams calendar/app
-Using the meeting link from an email
3.When the assistant is in the meeting, what role does Teams show next to their name? (People pane > their name > it will say Organizer / Co-organizer / Presenter / Attendee)
The initial response may not fully address your needs, but it will help me better understand your situation and give the advice. Thank you for your patience while we work through it
