I've reached the end of my patience. I am trying to transfer my e-mail folders from Outlook 2002(running XP) to a new laptop with Outlook 2007 (Vista). When I try to import, I am told the .pst folders are not .pst folders. I exported them with Outlook as a .pst and the extension remains .pst, I just cannot get them to import. This state of affairs applies to Inbox (and sub folders), Sent mail and all other folder. I was able to import my Contacts. I do not believe there is an issue with XP vs. Vista. I tried Dell and for a hefty price, they will attempt to assist. I thought I might try here first for any advice. TIA.
