Copy of an item is created in the Version subfolder in an Exchange Server 2010 environment

Applies to: Exchange Server 2010 Service Pack 3Exchange Server 2010 EnterpriseExchange Server 2010 Standard

Symptoms


Consider the following scenario:
  • You enable single item recovery for a mailbox, or place a mailbox on litigation hold in a Microsoft Exchange Server 2010 environment.
  • You log on to the mailbox by using Microsoft Outlook.
  • You change certain properties of a message item and then change the properties back. Then, you save the item or leave the item open for several minutes so that the item will be saved automatically.
In this scenario, a copy of the message item is added to the Versions subfolder of the Recoverable Items folder.

Note The expected behavior is that no new item is added to the Version subfolder because the item is not changed.

Cause


This issue occurs because the Exchange server considers the properties of the item to be changed. Therefore, the Exchange server creates an unnecessary version of the item in the Recoverable Items folder.

Resolution


To resolve this issue, install the following update rollup:
