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: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
  1. Start Registry Editor (Regedt32.exe).

    • To change the organization:

    • To change the server:
