I tend to prefer to IMPORT the old Outlook 2003 data (saved/exported to a
PST file) into new Outlook account/mailbox that has been setup for Exchange
only. Why? Because it (1) creates a backup of your Outlook 2003 data
(just in case!), (2) allows you on IMPORT into Exchange mail folder to
determine what folders are imported, where and (3) you can determine what to
do in case of DUPLICATE entries, and finally (4) allows some control over
what data is imported into new mailbox (filters, etc).
Although COPY-PASTE does work, it can be slower using GUI interface. I
have also seen errors in terms of codepage translation between Outlook and
Exchange hosted data... and copying calendar entries is sometimes not so
"easy" usign the GUI. I always feel too that the resulting Exchange
mailbox is possibly more "defragged" as the data is imported sequentially...
not sure if GUI does the same.
Just my comments from my experience...
