Important information for Outlook Web Access users about Outlook Web Access customization

When you apply an update rollup package, the update process modifies the Outlook Web Access directory names. Therefore, after you apply an update rollup package, you must re-create Outlook Web Access customization details. These details may include company logos and custom forms.

We recommend that you make a backup copy of any customized Outlook Web Access files before you apply the update rollup. For more information about Outlook Web Access customization details, visit the following Microsoft Web site: For more information about how to create Outlook Web Access themes, visit the following Microsoft Web site: If you are a CAS Proxy Deployment Guidance customer, and if you have deployed CAS-CAS proxying, apply the update rollup to the Internet-facing Client Access servers before you apply the update rollup to the non-Internet-facing Client Access servers. For other Exchange Server 2007 configurations, the order in which you apply the update rollup to the servers is not important.

Additionally, you receive an error message that resembles the following if you use Microsoft Update to apply the update:

Cause

This issue occurs if a silent installation of the update rollup encounters a "File in use" scenario. In this scenario, a file that is updated by the update rollup is being used.

Workaround

To work around this issue, view the Application log events that are mentioned in the "Symptoms" section to determine which file is being used. Then, make sure that the file is not being used when you install the update rollup.

Additionally, recover the original state of the Exchange Server services. To do this, use one of the following methods:

•	If this is the first time that you experience this issue, open Exchange Management Shell, and then run the ServiceControl.ps1 AfterPatch command from the following location: \Program Files\Microsoft\Exchange Server\Bin.
•	If this is not the first time that you have experienced this issue, use the Services Microsoft Management Console (MMC) snap-in to manually configure the Startup type setting of the services and to start the services. Perform this procedure before you try to reinstall the update rollup.
