Migrated email from exchange 2007 to exchange 2010 . Everything seems fine except a user told me some of her items in her calendar from earlier in the year are missing. I turned the old server back on as I hadn't decommissioned it yet and she said they are now back. Another user also said older calendar events that were sent from someone else were missing ( all the ones he had put in were still there) Is there something I need to do to transfer older calendar items over? I did go to System public folders and under free/ busy I went to the replication tab and put the new server public folder in there. I have no idea how to tell if it was successful or not or if that would have even fixed it or not. Any ideas?
