Symptoms

Consider the following scenario:
  • You place a mailbox in a Microsoft Exchange Server 2010 environment on litigation hold.
  • You apply a retention policy to the mailbox.
  • You press Shift+Delete to permanently delete items or delete items in the Deleted Items folder in Microsoft Outlook. This action moves the deleted items to the "Recoverable Items\Deletions" folder.

    Note
     You can view the "Recoverable Items\Deletions" folder by using the Microsoft Exchange Server MAPI (MFCMAPI) tool or by using the Recover Deleted Items tool in Outlook.
  • You enforce the retention policy manually or the retention policy is enforced automatically when the retention age limit is reached.
In this scenario, the items remain in the "Recoverable Items\Deletions" folder and are still returned in a discovery search.

Note The expected behavior is that items are moved from the "Recoverable Items\Deletions" folder to the "Recoverable Items\Purges" folder and are no longer visible to the user. When the retention age limit is reached, the Managed Folder Assistant removes the items from the mailbox database.

Cause

This issue occurs because the Managed Folder Assistant does not check whether the items in the "Deletions" folder are expired if litigation hold is enabled. Therefore, expired items are not removed.

Resolution

To resolve this issue, install the following update rollup:
2785908  (http://support.microsoft.com/kb/2785908/ ) Description of Update Rollup 5 version 2 for Exchange Server 2010 Service Pack 2

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
