If no one answers I'll ask internally (I'm in Microsoft but just an engineer and not in teams), I can tell you that in our org we don't have access to customer data, actual customer data is encrypted anyway and every access to a production machine is recorded, audited and has to be justified legally (and is very rare to the point I haven't _actually_ seen it done except to literally learn how to go through the process on a machine with no dat).

I'm also curious what the ToS says about teams, if it allows it I'd be pretty disgusted and I was very surprised Zoom does this..
