We are looking to install Update Rollup 3 on our Exchange 2007 SP1 servers. The two mailbox servers are in a CCR cluster configuration. Is there anything special we need to do for these two boxes related to the install? I have looked for rollup 3 installation documentation for CCR servers, but have not found anything. Any thoughts / experienceswould be appreciated. Thanks.

Hi, Nothing special you need to take care Read Rollup installation troubleshooting session in below article for the know facts before installing.. http://msexchangeteam.com/archive/2008/07/08/449161.aspx Procedure is here Applying Exchange 2007 Update Rollups to Clustered Mailbox Servers http://technet.microsoft.com/en-us/library/bb885043(EXCHG.80).aspx How to Install Update Rollups in a CCR Environment http://technet.microsoft.com/en-us/library/bb885047(EXCHG.80).aspx

Thank you for the info. It was exactly what I was looking for.
