Moving my pst-file to another location

That is actually easier than it looks; move the pst-file when Outlook is closed to its new location and then start Outlook. Outlook will now nag that it can’t find the pst-file and allows you to browse to the new location. Point Outlook to it and you’re done!

Locations of the pst-file

Of course you’ll need to know the current location of the pst-file fist. You can get an overview of your currently connected pst-files via;

• File-> Data File Management… (Outlook 2007 and previous)
• File-> Info-> Account Settings-> Accounts Settings…-> tab Data Files (Outlook 2010)
• The Mail applet in Control Panel.

Quickly open the folder location of your pst-file via the Data Files tab.

The defaults locations are;

• Outlook 2010 
  Pst-files are placed in a sub folder called "Outlook Files" in your "(My) Documents" folder.
• Windows Vista and Windows 7
  C:\Users\%username%\AppData\Local\Microsoft\Outlook
• Windows XP
  C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook

Note 1: Never overwrite any existing pst-files. This will corrupt your mail profile and then you’ll need to recreate it.
Note 2: Make sure you point it to the same pst-file and not another or you’ll corrupt your mail profile.
Note 3: Don’t make Outlook connect to pst-files on a network share. This is unsupported.
