Changing UID in hidden message to prevent re-downloading

Hi there!

I wasted maybe 5hours today, trying to get a solution to my problem. Looking through the postings, I figured this might be the best area to post:

I moved a PST folder from my old laptop to my new laptop, and when I created the POP3 mail account, Outlook wanted to download all the 14k+ messages on my account. Not an option, unfortunately

I researched a bit, and found some guys with the same problem - but no real solution. A hint was provided by an MVP in another forum:

"The message list is stored in a file on the hard drive in Outlook 2000 and
its linked to the acct in outlook on that machine so you can't copy it to
another computer. Newer versions store this file as a hidden message in the pst, but again, its tied to the acct via a GUID so you can't use it on other computers. If the second machine does something to delete this hidden message then the first machine may re-download the messages."

OK, so far so good - I tried to figure out how to find that hidden message, and change the UID to reflect the most current email I have in the PST file, but I had no success locating this message with OutlookSpy or MAPIViewer.

Is there any solution for my problem?

Cheers,

Bernhard
