Techie131,
Nope, in Outlook you're stuck with using the modified date. Actually uses the more recent of either the modified or sent date, but that is an irrelevant fact since ANYTHING you do (barring opening it, that is) to the e-mail changes its modified date. I had several users ask why some items which were sent 6 months ago were not being archived within the 6 month time frame. I did a lot of Google-ing to find this info and there was nothing to the contrary of that statement.
Sorry, mate.
As to your issue, you'd need to check the folder setting for each subfolder in the PST. So long as it's set to archive to the default location (or any location for that matter), it should be able to do so. BTW, the default on folder creation is NOT to archive, so make a check on those folders.
Luck to ya!
