XADM: Changing the Exchange Organization Name

Changing the Microsoft Exchange Organization name can be complicated. If you change the Microsoft Exchange Organization name, you must reinstall Microsoft Exchange Server on all servers in all sites.

This article explains how to change the name of a Microsoft Exchange Organization.

To change the name of a Microsoft Exchange Organization:

1. Copy all user mail to Personal Folders (PST file).
2. Copy all Public Folders to Personal Folders (PST file).
3. Using the Microsoft Exchange Server Administrator program, export all mailboxes, custom recipients, and distribution lists to a .csv file.
4. Modify the .csv file created in Step 3, replacing all instances of the old Organization name with the new name.
5. Remove and reinstall Microsoft Exchange with the required Organization and Site names.
6. Using the Microsoft Exchange Server Administrator program, import all the data from the .csv file created in steps 3 and 4.
7. Move the mailbox and Public Folder information from the PST file(s) created in steps 1 and 2 to the server-based store.

Follow these steps on each server in each site of the Microsoft Exchange Organization. Reinstall all connectors. If the Key Management server was installed, you must reinstall it. All mailboxes must be security enabled again.

If system administrators do not want to manually create new profiles for the users, they can use the Modify Profile Resource Kit utility to automate this process. To download the Modify Profile utility and related documentation, please visit the following Microsoft Web site:
