Consider the following scenario:
  • You use an Internet Message Access Protocol version 4 (IMAP4) client application to connect to a Microsoft Exchange Server 2010 mailbox.
  • You perform a content search on the mailbox. This causes the client application to call the UID SEARCH TEXT {n} IMAP command to the Exchange Server 2010 server.
In this scenario, the IMAP4 service on the Exchange Server 2010 server does not send a response. Therefore, the IMAP client application is not responding and the content search fails.


This issue occurs because Exchange Server 2010 can only respond to the SEARCH TEXT {n} IMAP command. However, Exchange Server 2010 does not respond to the SEARCH TEXT {n} command if UID is included.


To resolve this issue, install the following update rollup:
2529939 Description of Update Rollup 3 for Exchange Server 2010 Service Pack 1


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