I want to add a new data-store to our current 2010 exchange server.
This is to migrate some users who we don't need to backup from the main DB.
We also want to offline defrag the main DB and getting old users off it should make it faster.
The current size of the mail store is 255GB.
Are there any issues I should be aware of?
When I migrate a mailbox to the new DB does it automatically defrag?
When I migrate a mailbox to the new DB does that space get freed up in the old DB?
