Important information for customers who install the update rollup on computers that are not connected to the Internet

When you install the update rollup on a computer that is not connected to the Internet, you may experience long installation times. Additionally, you may receive the following message:
"Creating Native images for .Net assemblies."
This behavior is caused by network requests that connect to the http://crl.microsoft.com/pki/crl/products/CodeSigPCA.crl Web site. The network requests look up the certificate revocation list for each assembly that native image generation (NGen) compiles to native code. However, the Exchange Server is not connected to the Internet. Therefore, each request must wait to time-out before it moves on. To fix this problem, turn off the “Check for publisher’s certificate revocation” security option on the server that is being upgraded. To do this, follow these steps:
  1. In Internet Explorer, select Tools, select Internet Options, and then click the Advanced Tab.
  2. In the Security section, click to clear the Check for publisher's certificate revocation check box.
  3. Click OK to close the Internet Options dialog box.

We recommend that you clear this security option in Internet Explorer if the computer was in a tightly controlled environment. When setup is complete, recheck the “Check for publisher’s certificate revocation” check box.

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


When you apply an update rollup package, the update process overwrites the Microsoft Outlook Web App (OWA) files if it is necessary. If you change the Logon.aspx file or you change other OWA files, customizations are overwritten. Then, OWA is updated correctly. After you apply the update rollup package, you must re-create OWA customization in the Logon.aspx file. We recommend that you make a backup copy of customized OWA files before you apply the update rollup. For more information about OWA customization, visit the following Microsoft Web site:

If you are a Client Access server Proxy Deployment Guidance customer, and if you have deployed Client Access server to Client Access server (CAS-CAS) proxying, you must apply the update rollup to the Internet-facing Client Access servers.

Note Make sure that you 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 2010 configurations, the order in which you apply the update rollup to the servers is not important. For more information about CAS-CAS proxying, visit the following Microsoft Web site:
