Recoverable Items Audits, CalendarVersionStoreDisabled, Versions, Deletions and other problems

When we have problems with TotalDeletedItemsSize (too large) we should check all items in Recoverable Items folder and subfolders.

To do this we should use following command:

Get-MailboxFolderStatistics -Identity JSmith -FolderScope RecoverableItems | Format-Table Name,FolderPath,ItemsInFolder,FolderAndSubfolderSize


As a result we will get list of all Recoverable Items subfolders and information how much space they use.



How to remove all items from Deletions we wrote in article:

 Exchange 2010 Database size growing problem



In general, type the following command and Recoverable Items folder size should be significantly reduced:

Search-Mailbox -Identity JSmith -SearchDumpsterOnly -DeleteContent

Export mailbox to pst larger than mailbox size


When we export mailbox from Exchange Server to .pst file, we can see that size of this .pst file is larger than mailbox size in Exchange Management Console (EMC).

We can export mailbox using New-MailboxExportRequest like below:

New-MailboxExportRequest -Mailbox "JSmith"  -Name JSmith -FilePath \\server\share\JSmith.pst


When we check .pst file size we will see that it’s larger than mailbox size.


Size difference between mailbox size and .pst export file size is caused by Recoverable Items.
When you export mailbox to .pst, all items in mailbox including Recoverable Items will be exported to .pst file. But when you check mailbox size in EMC, you check size of mailbox without Recoverable Items, so this is size difference.
In Recoverable Items you can find all items deleted by user which can be restored and calendar versioning it’s dumpster.


If  you want to check mailbox size with deleted items yet not purged (Recoverable Items) you have to use powershell and Get-MailboxStatistics CMDlet like below:

Get-MailboxStatistics JSmith | Format-List StorageLimitStatus,TotalItemSize,TotalDeletedItemSize,ItemCount,DeletedItemCount


As a result you will get mailbox size, and also Recoverable Items size, when you add them you will get total mailbox size after export to .pst file.
