Hello, Can I enquire what type of maintenance do you action or should action on your mailbox databases.  Our databases are 200GB in size and our users love email where sometimes disk space can go quite quickly.  We use to schedule 6 - 9 monthly offline defrag, integrity & consistency checks of the databases but due to their size it is getting harder now to action this.  We also use Enterprise Vault for email archiving.  We get to the point where we have 15GB of disk space remaining so we run an offline defrag or have to extend the drives.   We ran a defrag pass across 2 stores at the weekend and got 20GB from each store back - we have also changed the archiving policy from 12 months to 3 months so a lot of space will be due back from this but do we have to run an offline pass or are there 3rd party apps that can do this online?  Our mailbox server is an Exchange 2007 Single copy cluster. Can I ask what do you do in these situations?  Are there any decent 3rd party tools you use to action this?  Do you just throw disk at it? I would appreciate your comments on this. Many Thanks.

Thanks. We'll let you know when a new response is added.

Mailbox management policies are your best firend. If you are archiving then why do you need to allow users to keep all their mail in their mailbox? They have access to their archived mail don’t they? I would suggest you implement and enforce a retention policy. Ours is 15 months. Anything older than that is automatically deleted. Since users can access their archived email that is where they go to find older mail, saving us space on our Exchange servers. We have just a 30 day retention on the deleted items folder. If you move it to your deleted items, then why would you need it after 30 days? Users are lazy and don’t take a moment to empty that folder otherwise. I found one user with nearly ALL her mail sitting in deleted items, and sorted into folders even! No more!

The best thing you can do to backup your entire database is to use incremental backup using a third party back up software. You really need another hard disk drive which has a large storage space for your future files to backup.
