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.
- Stop Outlook if it is running
- 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
- Start Outlook. It will give an error "The file <filename> could not be found". Click OK
- You can now browse to where you moved the file to. Select the .pst file and click Open.
- 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.
