Interesting. In my case I had Outlook 2000 installed on a WIN98 machine. My folders were getting pretty big and I was about to export them all so that I could import them to Outlook 2003 on my WINXP machine.
I did something crazy. I ran the "detect and repair" under help in Outlook 2000 and I believe this is why my folders are empty when I import them into the WINXP machine. After running this utility folders are "recovered".
Here's a quote from Microsoft on the process: "recovered folders are usually empty, because this is a rebuilt .pst file. You should also see a folder called "Lost And Found" (without quotation marks). This folder contains folders and items that the Inbox Repair Tool recovered."
To make matter worse my WIN 98 machine decided to go 'blank' on me (turned out to be video drivers) and I reinstalled WIN98 thinking I had a good backup. I had files dating back to 1996. I backup my Outlook files on my "D" drive.
So I'm not quite sure what problem I have at the moment. The pst file that I'm trying to import does not look empty (0.5GB) but I'm not getting anything. I'm not giving up - too much at stake.
Thanks for your post.
