Video Share is disabled by the Administrator
Allan thank you Allan for posting this and for doing the legwork to figure out the exact set of circumstances that break video sharing for guests. I used your notes, and reproduced the situation exactly as you wrote it out. I confirmed that if a Guest uses web client to join meeting, and they connect to the meeting BEFORE the Organizer does, Video Sharing will show as disabled by the Administrator. If the Guest joins AFTER the Organizer starts the meeting, then Video Sharing works great. We will advise our users to simply end the meeting and then immediately rejoin (Microsoft gives you a rejoin button after you end the call).
I reported this 'bug' to Microsoft 365 as well.
We've been experiencing this too, so in a way it's good to see others have.
Given that we don't appear to get this issue with licensed Teams users, and that the deciding factor seems to be that guests enter the meeting after the organiser (or are admitted via the lobby), I think it may be by design. Whether accidental or deliberate, it means that a licensed user can't set up full-function Teams meetings on behalf of unlicensed guests unless they attend the meeting. That's something Microsoft definitely wouldn't want people to be able to do.
