I need to do an offline defrag on my Exchange 2003 system and I need to find out approximately how long the process would take. I’ve got 2 storage groups, one with 4 mail stores and the other with 1. The first is taking up about 400gb total. I have cleaned out about half that amount in old mailboxes and a mailbox that was being journaled to. The second storage group contains about 6gb.
Any way to figure out how long this might take? I’m trying to make sure I allocate enough time for this to complete.
