We have upgraded servers to 8.5.1. Also upgraded clients to same. For a select few people, when we upgrade their mailfile to the new 8.5. Template their calendar no longer shows the subject line for the events in the calendar. Instead it only shows a number, which is the appointment type.
Refreshing design again does not fix.
Replacing design again does not fix.
Even tried deleting the Calendar view and then replacing design again, but no luck.
Only solution we have found is to make a new replica of the mailfile and then replace the old mailfile with the new replica.
QUESTIONS: Why does this happen? What else can we do to correct it besides the new replica hack?
