Meanwhile, last time I had a video call in Teams, when I went into the call settings to change my microphone, my computer slowed to a crawl and became inoperable until the person who called me ended it. We eventually settled on a phone call. When I try to share a file over a certain arbitrary size limit, Teams refuses to do so, indicating some undesired and complicated permissions interaction with Teams and SharePoint.
