we have Exchange Server 2010 at disaster recovery site which is running out of space, some of the staff who were high on the list in terms of mailbox storage has been contacted, and their mailboxe size has been reduced.
Mailbox clear out doesnt reflects the size on the Exchange Server, so we had to purge the accounts.
But it still didnt represent the free space on the physical drive, so I am planning to do an offline defragmentation?
So can you please assist me in carrying out the steps to do an offline defragmentation, and if anything goes wrong how can roll back to where i was?
Also offline defragmentation, how long it will take? and what it affect the primary site?
