How can I change the organization name of my Exchange server? I'm running Exchange Server 5.5 Service Pack 2 (SP2).
The tool you're looking for is the Move Server Wizard (MSW), which you can obtain from the Exchange Server CD-ROM or from Microsoft's download site. MSW lets you take a server in one organization and move it to another organization. In your case, you can just tell the MSW to move your server to the organization that you want. Be sure to read the release notes completely, though, because using the MSW properly can be tricky. Before proceeding, I also recommend that you read Tony Redmond, "Move Server Wizard War Stories," August 1999.
