Additional meeting and call-related features and issues within Microsoft Teams for Education
Hi Diane,
Does the recording indicator show red? If so, it indicates someone else in your meeting has started recording the meeting. And in a meeting, only one recording can be made. So you can also ask the presenters to help you record the meeting.
While if every presenter in this meeting cannot record the meeting, it could be related with Teams meeting policy in Teams admin center. In this scenario, please try to contact the Office 365 admins in your organization to check if the cloud recording is enabled.
Regards,
Marvin
