Emergency action required for this one. Our exchange 2010 sp3 box is running out of space. I had users cleanse their mailboxes and have removed all old users mailboxes. At that time I checked the database and it was physically 600gb in size with 7gb white space and this left approx 50gb hard disc space free. I ran a PS command to purge the dumpster for a few individual mailboxes. Now the db is 600gb with 40gb white space but only 20gb hdd capacity left! Server is maxed out on 146gb drives. It is due to be replaced next year but may need to be brought forward.
I do have access to a Hp DAS but it's populated with 500gb sata drives. I had thought of hooking this to the exchange server ,creating a new mail db on there and doing a mailbox move. Any valid reasons why this would be bad or indeed any other suggestions to keep this box going?
