Important information for customers who install the update rollup on computers that are not connected to the InternetWhen you install the update rollup on a computer that is not connected to the Internet, you may experience long installation times.

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:
