Exchange 2007 Temporary Clean Up

Hello,

Our company just took over a new account.  The disk that their exchange 2007 store is on has only 4GB left.  I have convinced them to move to a hosted email solution, however, i would like to give us some cushion so nothing bad happens.  

What I did (which I thought would clean up some space) was had two users with 20GB mailboxes archive half their mailbox.  I set the deletion settings to 1 day and ran a backup.  I checked the size of their mailboxes and they are under 10GB each yet  I am not seeing this reduction in actual disk.

Googling this topic would consume my day.  I just need to know any way to give me some cushion until we migrate them.  There is no other disk with more than 40 GB of free space on the network.

To get space back from the MDB, you need to do an offline defrag.  This is the only way you can recover space back to the disk after a large deletion from the database.

Dismount the database and from a dos prompt run

C:\program files\microsoft\exchange server\bin\Eseutil /d [c:\program files\exchange server\mailbox\<storage_group_name>\<database_name>.edb] (Replace what's in the [ ] with your path to the database.)

Additionally, check your application event log - filter for even 1221 and check to see how much free space could be gained from an offline defrag.  Make sure you're looking at the events that discuss your mailbox database, not your public folder database.

Finally, when you do an offline defrag, you need approximately 110% of the disk space available as a complete copy of the database is performed.  If you don't have the space, you'll need to find space.  You can use additional switches with ESEUTIL to tell it where to use space.  This sounds like a problem for you.

Last idea - download treesize free and run it on your drive.  See if there's some large log files or something taking up space you can clean up.  This has saved me so many times!

Oh - and for those additional switches and such - http://technet.microsoft.com/en-us/library/aa998863(v=exchg.80).aspx
  /t is the option you're going to look for.

You would need to use a logic drive, so keep that in mind.
