Believe it or not, I FINALLY figured this out.

I was still on my manager's computer with both our .pst files; his as the
original Outlook.pst, and mine as Outlook-2.pst (I renamed my copy before I
uploaded it).

1. While in Outlook, and in my manager's Personal Folder, I created a new
folder and called it Contacts-1.

2. I scrolled down to the duplicate, which held all of my Personal Folder
items, and right clicked on my Contacts.

3. I was given the choice to "copy the selected folder to the folder" I
scrolled up to his Personal Folder and copied my contacts to the new folder,
Contacts-1. At this point, I am pretty sure that the contacts will be saved
in his .PST file.

4. I scrolled back down, right clicked on the duplicate/my Personal Folders
and chose "Close Personal Folders." It promptly disappeared, along with all
duplicates of the Contacts and Calendar, my inbox and all my folders.

5. I clicked on Contacts-1, chose select all, and then I dragged all 657
contacts into his regular Contacts folder. Finally, I right clicked on
Contacts-1 and chose "Delete."

6. I checked under Tools, Account Settings and Data Files just to make sure
the only .pst file there was his. Sure enough, Outlook-2.pst file was no
longer there.

HURRAH!!!

Whew, what an odyssey. You have to wonder why they bothered to make the
lackluster Import-Export utility instead of just telling everyone how to do
this?

Gordon, you are a scholar and a gentleman. I cannot thank you enough for
your patience and kind replies. It is almost 6:30am here and I am still at
work! Time to go home and sleep until NOON.

In his Outlook, close your pst file. Then in Windows explorer, delete it.
On your machine, create a new pst file and copy the contacts into it. Close
Outlook and copy that new pst file to your boss's machine. then repeat the
process.
