Situation is this:
If I boot my computer and log into the domain, I am able to access
email (via Outlook 2003 on WinXP with no problems. I close outlook.
(BTW: The PST file is located on a shared drive on a Windows 2000
fileserver on the lan.)
After some time passed (say 1 hour) without using outlook, I re-open
Outlook, I get the message that "The path specified for <path to
shared drive on file server>.pst is not valid". I then have to log
out then back onto the computer, and it works fine.
