If you are using MS Outlook (any version), you will notice that there is no way to rename the mail profile from Control Panel (see Figures A and B).

I knew that most of these settings are stored in the registry, so I ran a search for every instance of Profile. I did find where the change was and confirmed my suspicion that this setting can be modified using the registry.

Note: As always, edit the registry at your own risk. Make sure you have a reliable backup of the registry; some erroneous edits could render your system unbootable.

The only way to rename your Mail Profile is through direct editing of the registry.

1.       Launch Regedit and browse to

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\ (Figure C).

2.       Now, edit the DefaultProfile key by right-clicking and selecting Modify.

3.       Rename the key to how you would like it to appear.

4.       Next, right-click the profile you just renamed. It will be located at HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\bbird@igius.com.

5.       Right-click the profile and click Rename and rename it to the same as above.

6.       Close the Registry editor and then re-open the Mail Applet in Control Panel to find that the Mail Profile has been successfully renamed, as shown in Figure D.
