When trying to archive my Personal Folders to an Archive I get the above error message.
I checked this microsoft message: http://support.microsoft.com/kb/888089
but that is not the problem. Both my Personal Folders and the Archive are of type "Personal Folders", and not of type (97-2000).
Couple of things which I am wondering may be the problem:
(a) When installing Outlook 2003 a few years back I did copy a lot of items from older Outlook folders into the new Personal Folder. So even though the Personal Folder is in 2003 format, it may have items that were originally in 97-2000 format.
(B) My PST file for the Personal Folder is 6.2GB, that's why I'm trying to archive it now (I don't have autoarchive set).
