How can I remove multiple Personal Folders in the Folder List and Mail Navigation?
Check Tools > Services (or File > Data File Management) and remove the extra Personal Folders reference if there is one listed. Otherwise, you should be able to just create a new profile (Start > Settings > Control Panel > Mail > Show Profiles > Add, to get rid of the issue. Still no dice, you can try this… Select Start > Run enter Regedit and select OK. Check HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WindowsMessaging Subsystem\Profiles\profilename\Software\Microsoft\WindowsNT if Windows NT or 2000). The subkeys are hexidecimal numbers. Find the one(s) that reference the .PST file and select it. Export that key (from the Registry menu) to a .REG file for backup purposes, then delete it. If you seem to have multiple keys pointing to the same PST, try opening Outlook after you delete the first one. If you find you deleted a “good” PST entry, import the key from the .REG file to which you exported it, then try the next one.
