This is all AFAIK. Maybe I'm wrong. But even where I'm right, Microsoft is likely to change it so its probably only correct for a small time window.
The meeting will be automatically shared regardless. The person recording doesn't control how its shared.
You can't delete anything from the teams chat including the shared link to the recording.
To removed the sharing you have to remove each person one by one. We often have meetings with 50~200. Its not viable.
I don't know if don't share doesn't work or is just laggy.
Either way people can still access it until I break the link manually. I rename the recording and move it. Then the link doesn't work, but I can't remove it.
I can kick off a recording, and leave the meeting, the recording will continue until the meeting ends or everyone leaves, or it hits the storage/time limit.
This often happens because I'm in area of bad reception and I kick off a recording from my mobile, then continue my journey, or my internet drops out.
Which is handy, but its a different to how the rest of the Teams meetings/chat work, in those if I leave I can't see what happens when I'm not there.
Its also not how the SharePoint site under the MS team work. I can set specific permissions there that do not mirror the MS Teams Meeting/Chat permissions.
If its an interview, it will be shared automatically amongst everyone in the meeting. No way to control that.
What we do, is leave the meeting and start a new one that the interviewee hasn't been invited to.
We aren't daft enough to record either meeting, so it can't be requested under FOI.
Every interviewee gets a seperate meeting every review/scoring of the interview is a seperate meeting also.
I want to set where recordings are saved to and where I can set the permissions. I don't want to be nannied by Microsoft assuming what they think I want is actually what I want.
