Hi all,
we've recently migrated half our environemnt to Exchange 2010 and our storage has taken quite a hit with the new changes, i.e. SIS removed. We seem to be having issues with the databases not reclaiming white space after Enterprise Vault archiving also but
that's a seperate issue altogether. My main question is regarding these three settings from the following command
Get-MailboxDatabase -Identity "Mailbox Database" | fl Recoverable*,DeletedItem*
RecoverableItemsQuota : 30 GB (32,212,254,720 bytes)
RecoverableItemsWarningQuota : 20 GB (21,474,836,480 bytes)
DeletedItemRetention : 20.00:00:00
As you can see, everything is default, except we've raised DeletedItemRetention from 14 to 20 days. In Exchange 2007 we have this at 30, but we decided to reduce by 10 to see if our problem of disk running out slows down.
My question is, given we've got 7 databases on this one Exchange 2010 SP3 server and looking at the RecoverableItemsQuota which is 30GB for each database, does this mean that overtime we're looking at a total of 210GB of recoverable items on top of the actual database size for the mailboxes etc OR will having the DeletedItemRetention make sure that the entire quota is cleaned up because of the 20 days limit?
I have another example of my question. One user we had to restore 10GB worth of emails from Enterprise Vault. So they're mailbox grew to 10GB we exported to PST then deleted the 10GB worth of email, which is currently sitting in their TotalDeletedItemSize. Would this clear out after 20 days, or will it remain whilst the RecoverableItemsQuota is still below teh 30GB limit?
Quite confusing, need to determine ASAP why the DB growth is so high and why we're not getting white space back from after archiving.
We're running Exchange 2010 SP3 with Enterprise Vault 10.0.3, we archive emails after 12 days, we do leave the stubs in the mailbox.
Thanks in advance.
