Exchange 2007 Roll-up 5 Released

Exchange 2007 RU5 was released yesterday approximately 6 weeks after RU4 was released. The current release corrects numerous bugs with the complete list found at The roll-up does not require a reboot but may take a considerable amount of time to install so be prepared. In testing I have not encountered any issues installing the roll-up and unlike RU4 all services did start as expected. Expect to see the RU released via Microsoft Update the first half of December. Until then, you can download the update directly from Microsoft Download at

Eliminating the Outlook 2007 Security Warning w/o Using a UCC Certificate

This tip was sent to me from a good friend and business associate, John Lockett.

This procedure gets rid of the security warning in Outlook 2007, in cases where you apply a standard SSL certificate to the default web site, and the FQDN is different from the AD FQDN of the exchange server. First run the following commands in the Exchange Management Shell on

your Exchange 2007 CAS so that we would have a backup listing of the current settings:


Get-Clientaccessserver | fl > backupCAS.txt

Get-WebServicesVirtualDirectory | fl > backupWeb.txt


Now change the settings to remove the warning.


Set-Clientaccessserver -AutoDiscoverServiceInternalUri https://public FQDN, as appears in the certificate>/Autodiscover/Autodiscover.xml

set-WebServicesVirtualDirectory "\EWS (Default Web Site)" -InternalUrl https://public FQDN, as appears in the certificate>/EWS/Exchange.asmx


Wait a few minutes for implementation to complete.
