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.
So I'm here because I have a similar issue (i.e. External users don't see 'Join' button when in Teams).
I've just started using a workaround where I (the meeting creator) copy the 'Click here to join meeting' bit from the Meeting details section and I paste it into the 'Posts' tab in the relevant Team/channel.
External users can then click on that link to 'start' the call.
I believe that MS have left the 'Join' button out for guests because they don't want guests to 'start' a meeting. Guests do see the 'Join' button once a call has been started (i.e. by someone else).
Not sure if that helps, but it's what I'm going with for now.
