EX2010 SP2 Rollup1 - DAG I noticed that our database is growing very large very quickly; the size on disk used is roughly 500GB yet the database reports 285GB? WhiteSpace (MB) : 93 MailboxCount : 2085 Server : MBXSERV2 LastFullBackup : 8/7/2012 12:01:07 AM DatabaseSize (GB) : 284 DatabaseName : MBXDB1 AverageMailboxSize (MB) : 118.660911270983 I looked at mailboxes and they seem normal, so I looked at deleted items and one user in particular; if you notice the 11.99 GB for today, yesterday that was at 10GB. This seems to be happening for all users just not to this extreme, our retention policy permanently deletes items in the deleted items bin after 90 days and after 2 years it does the same for sent items, this wouldnt cause this problem would it? Last backup was ran this AM I cant find anything in the event log. The below user doesnt use active sync and only uses OWA. Other users have items filling up in this location as well, I am stumped at this point. NOTE: This cmd does not remove these emails: Search-mailbox -identity <alias> -SearchDumpsterOnly -DeleteContent RunspaceId : xxxxxxxxxxxxxxxxxxxxxxxxx Date : 5/23/2012 11:54:22 PM Name : Recoverable Items FolderPath : /Recoverable Items FolderId : xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx FolderType : RecoverableItemsRoot ItemsInFolder : 52967 DeletedItemsInFolder : 0 FolderSize : 11.99 GB (12,873,571,057 bytes) ItemsInFolderAndSubfolders : 52980 DeletedItemsInFolderAndSubfolders : 0 FolderAndSubfolderSize : 11.99 GB (12,873,572,977 bytes) Jason

The root folder holds some calendar versioning data. If you disable it for just that mailbox as a test, do things look better for that user? set-mailbox <alias> -CalendarVersionStoreDisabled:$true Note some improvements in SP2 RU2 and SP2 RU3: Holy COW! Changes to Recoverable Items versioning in Exchange 2010 SP2 RU3

Hi Jason, Any updates?Frank Wang TechNet Community Support

Hi Jason, Any updates? Frank Wang TechNet Community Support "I have tried the command, however user was already at 20GB, is there anyway to reclaim this space/clear out this folder?" Never-mind I didn't wait long enough, checked this AM and user is at: Should I enable this again?
