Additional meeting and call-related features and issues within Microsoft Teams for business
I have had 4 or 5 sessions with Microsoft techs. At the end of it, we manage to schedule a meeting that works. It takes about 45 minutes to work through it with them; so that is not a solution for a daily basis. I think I have developed a half-measure that seems to work (hopefully will continue to work). When I have a meeting on my default account (which is the account for which I am an administrator), I sign out of everything Microsoft and then I log onto the default account through my web browser. The desktop app seems to trip up. But if I have signed out of everything and then go to Teams online and only to the account with the meeting, things seem to go as planned. Not a great solution; but at least I can host and join meetings.
