How can I change the location of my mail file in Outlook 98?

A. A. Your messages are stored in a .pst file, and by default this is kept in your personal profile space (%systemroot%/Profiles/<user name>/Application Data/Microsoft/Outlook). This is fine unless you use roaming files which mean you mail file is stored on a central server taking up space.

Fortunately moving you mail file is easy.

  1. Stop Outlook if it is running
  2. Move to you profile area and move your .pst file to another location (e.g. c:\savillj\outlook). Make sure the .pst file is no longer under your profile
  3. Start Outlook. It will give an error "The file <filename> could not be found". Click OK
  4. You can now browse to where you moved the file to. Select the .pst file and click Open.
  5. Outlook will then start as normal.

What this actually does is update one registry key, HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Microsoft Outlook Internet Settings\14780fd532f9d11181cc00600851c569\001e6700 and its value is the name and location of the .pst file.
