Missing "Join" button in Microsoft Teams calendar for meetings from external Users
StuartRK I have solved this problem by fixing the time on the windows machine, set it to be automatic over the internet. I hope this solves the problem.
David Mutschlechner I am playing with this right now, one of the people I support is a delegate for a VIP and the meetings she sends on behalf of him don't have the Join button but meetings she sends from herself do have the button. She only has "send on behalf" rights, not "send as" - it seems like the "send as" supports don't have this problem, their buttons show up for their meetings.
Edited: I take that back. We are still in a hybrid environment, we're in the process of moving mailboxes from on prem to in the cloud. It looks like the meeting we are missing the join button from was created before this user was moved to the cloud. The meeting is a series to last throughout the year. She re-created the series and the button appeared.
It happened to me a few times. Seems it's a bug from Microsoft, suddelnly I had no join buttons on ANY meeting (and I have many a day). Closeing and reopening didn't fix it.
Checking later, they reappeared. I had to open web teams and join from inside the meeting using a link.
Hope this is useful for someone. It's not you. It's a transient bug 🙂
