An Outlook user asks: "Without starting Outlook 2007, I moved the IMAP pst from C to D. I hoped Outlook would ask me where the file is. However it creates a new one in the same location. How do I make Outlook use the new location?"
That method is used to move *.pst files used by POP3 accounts, it won't work with the IMAP protocol. (Actually, it's not recommended that you use that method for any PST - you should move the PST then point the profile to the new location before opening Outlook.)
While we don't recommend moving the IMAP *.pst unless your drive space is tight, you can move the IMAP *.pst using the following steps.
This method works with
either Outlook 2003 or 2007.

Move the IMAP personal folder (*.pst)
First, close Outlook then make sure Outlook is not listed in Task Manager, Processes tab a few minutes after you close it.
This method will work with SharePoint and Internet Calendars, as well as HTTP accounts. You can’t (easily) move Outlook Connector message stores for Hotmail/MSN/Live accounts. In my experience, This method is mostly reliable but does occasionally get 'lost' and a new pst is made in the default location.
See To move a Personal Folders .pst file for instructions for moving POP3 pst files and Hotmail Connector files.
