By default, when you create a new Teams meeting, you are the only person who can act as a presenter. If you are creating a meeting on behalf of another user, you need to set them as the presenter so they can start and control the meeting:
- Create your meeting in the Teams application (or via the Web) in the Calendar and send it to any attendees (including the other presenter)
- Once visible in your calendar, open the meeting and click the "Meeting Options" button at the top
- This will open a web browser, and here you can select "Who can Present". The safest option is to select "Specific People" and then "Choose Presenters". You can only select from people invited to this meeting.
- Change any other options necessary and select "Save".
