How to clean up duplicate references to the same .pst file in the Outlook 2000 that is installed with Internet Mail only mode

When you use Outlook 2000 in Internet Mail Only (IMO) mode on a Microsoft Windows NT or Microsoft Windows 2000-based computer, you may notice more than one Outlook Today folder appear in the Folder List view.

This behavior can occur if more than one reference to the same Outlook.pst file in the registry.

To resolve this problem, there are two possible solutions:

• Change the Mail Delivery Point to a different Personal Folder.
• Delete the appropriate Registry Key that references the duplicate information.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To Change the Mail Delivery Point to a Different Personal Folder

1. On the File menu, point to New, and then click Personal Folders File (.pst).
2. Type the name of the new personal folder (.pst) file, verify and change the file location if necessary, and then click Create.
   
   NOTE: Do not use the name Mailbox.pst.
3. Verify and change the information if necessary, and then click OK.
4. If the Folder List does not appear, click Folder List on the View menu.
5. Right-click the new personal folder (.pst) file, and then click Properties for Personal Folders
6. Click to select the Deliver POP mail to this personal folders file checkbox, and then click OK.
7. On the File menu, click Exit.
8. Restart Outlook.
9. In the Folder List, right-click the personal folder (.pst) file that is not associated with Outlook Today, click Properties, click Advanced, and then verify that the path of this file is different than the one you created in step two.
10. Click OK, and then click OK.
11. In the Folder List, right-click the personal folder (.pst) file that is not associated with Outlook Today, and then click Close Personal Folders Name.
    
    NOTE: This closes the connection between Outlook and the folder, but it does not delete the connection.

To Delete the Appropriate Registry Key

Each reference to the Outlook.pst file or other .pst files is stored in a unique identifier ID folder stored in the following registry key:

• For Windows 2000:
  HKEY_CURRENT_USER\Software\Microsoft\Windows NT\Current Version\Windows Messaging Subsystem\Profiles\profilename\
  NOTE: You must step through the folders present in this registry folder, and look for an "001e6700" entry, which identifies the path of the .pst file. If you see that more than one entry exists for this profile, delete the duplicate.
• For Windows NT 4.0:
  
  Using Regedt32 for Windows NT, open the registry, and open the following path:
  HKEY_CURRENT_USER\Software\Microsoft\Windows NT\Current Version\Windows Messaging Subsystem\Profiles\username\Microsoft Outlook Internet Settings
  Open the folder to see the folders for the affected user, and to determine the unique identifier ID folder name that contains information for Outlook and links to files for the affected user.
  
  After you identify the additional unique folder, use RegEdit or Regedt32 to back up the specific unique folder, and then delete that folder. The next time you start Outlook, you will see one less Outlook Today folder in the Folder List view for that user. Repeat this procedure as needed, if multiple views of that folder exist.
