Of the top I apologize if this thread is redundant, but I couldn't find any answers in all related threads.
Setup:
Exchange 2007 + 2010 in co-existence mode (all servers are up to date on SPs)
60 users were on Ex2010 and due to bad design were migrated back to 2007
Most user mailbox sizes increased due to the move back but not by a large factor.
Problem:
User's mailbox in EMC shows as 168MB out of 180MB allowed
Outlook 2010 data file size shows as 681KB.
I did all the usual tests - compared OWA to Outlook, cached mode on/off, etc but the sizes are still different.
Ideas?
