Symptoms

Assume that you perform an Advanced Find search on a mailbox by using Outlook in online mode in a Microsoft Exchange Server 2010 Service Pack 1 (SP1) environment. In this situation, it takes a longer time to return results compared to a Microsoft Exchange Server 2007 environment or a Microsoft Exchange Server 2010 RTM environment.

Cause

This issue occurs because Exchange Server 2010 SP1 builds a restriction tree for a search.

To resolve this issue, install the following update rollup:
