Several staff members receive the error message 'The expiration date and time
for this message have passed.' when trying to update an existing meeting in a
calendar. It can be a one-off meeting or a series of meetings.
PA's are mainly the affected group of users (I suppose they have a lot of
meetings to arrange) and, as most here will know, that means we get to hear
about it, and our current lack of a solution, quite a lot!
I can't see any mention of a reason for this on the microsoft sites so far
and am at a loss to explain why a meeting which hasn't even occured yet could
have expired and cause issues for the userbase.
Please can anyone help?
