Consider the following scenario:
Log Name: Application
Two objtMessageView objects are used when an IMAP4 client issues a SELECT command or a STATUS command for a folder. However, the Exchange server does not release one of the objtMessageView objects for the previous folder when the IMAP4 client issues another SELECT command or another STATUS command for a different folder. When the mailbox has more than 250 folders, the IMAP4 client exhausts the maximum number of the objtMessageView objects on the Exchange server, and this issue occurs.
To resolve this issue, install the update rollup that is described in the following article in the Microsoft Knowledge Base:
(http://support.microsoft.com/kb/2685289/ )Description of Update Rollup 3 for Exchange Server 2010 Service Pack 2
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
