thanks. this was the exact answer i was looking for! great!
ya, his pst file is 3.8GB (!!) i copied his pst file from his laptop to another one that i have access to. i made his mailbox in Ex2k3 as default mail delivery location for the time being.
he has created too many subfolders as well as folders at the same level as Inbox. i put all items in one folder, Inbox, on the copied pst file. now, i'll have to copy it back to his laptop.
too many users pst files are larger than 1.4gb here. this is delaying the deployment of pst file size limit set in GPO...
