The information in this article applies to:

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

In some instances, you may want to change the Exchange Server organization, site, or server name to reflect changes in the Exchange Server structure, rather than removing and reinstalling the Outlook Web Access (OWA) component.


MORE INFORMATION

The Enterprise, Server, and Site registry values need to be modified on the OWA server to reflect the changes in the organization, site, or Exchange Server computer that the OWA server connects to.

To modify these registry values on the OWA server, you must edit the registry.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

  1. Start Registry Editor (Regedt32.exe).


  2. Change the following registry values, as applicable:


    • To change the organization:


      1. Locate the Enterprise value under the following key in the registry:


        2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\Parameters

        2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\Parameters
      2. On the Edit menu, click REG_SZ, type the site name, and then click OK.
