Important information for customers installing the update on computers that are not connected to the Internet
The following issues occurs if your computer is not connected to the Internet and cannot access the following Microsoft Web site:
You may experience long installation times with a corresponding message that shows
This is caused by network requests to connect to “http://crl.microsoft.com/pki/crl/products/CodeSigPCA.crl” Web site and look up the certificate revocation list for each assembly that Native image Generation(NGen) compiles to native code. Because the Exchange Server is not connected to the Internet, each request must wait to time-out before it moves on.
To resolve this problem, follow these steps to turn off “Check for publisher’s certificate revocation” on the server that you are upgrading.
When setup is complete, recheck the “Check for publisher’s certificate revocation” check box.
Important information for Outlook Web App users about Outlook Web App customization
When you apply an update rollup package, the update process overwrites the Microsoft Outlook Web App (OWA) files if it is necessary. If you have changed the Logon.aspx file or other OWA files, the customizations are overwritten to make sure that OWA is updated correctly. After you apply the update rollup package, you must re-create OWA customization in Logon.aspx.
We recommend that you always make a backup copy of any customized OWA files before you apply the update rollup. For more information about OWA customization, visit the following Microsoft Web site:
