I think the easiest way would be to add another email account to your Outlook 2016 and configure it to use

Then just drag emails from one send items folder to send items on other account

How to configure outlook to use office365 you can find here

Tom Cieslik:  That worked great.  To expand on this:
I had already set up a POP account amongst many.  That's where the SENT Items were located in Outlook 2016.
So, I set up a new IMAP account in Outlook 2016 per the instructions.
Then I dragged all the Sent Item messages for the one POP account into the Sent Items for the IMAP account.
(Did the same for the inbox for all the incoming messages to that account address).

The one thing that's unfortunate is that the Outlook 2016 Favorites got changed in some strange way.  Some folders remained while others just disappeared.  It's not catastrophic but will require setting up the Favorites again.

I just found that ALL of my message rules have been deleted.
I wish there were a backup of them.  I don't know if that's possible.

If you have rules in outlook -
1. Go to Rules and Alerts
2. Click Manage Alerts
3. Export Rules
