Outlook 2016 acting 'crazy'

I have a situation where - I'll be typing along in a message in Outlook and the program will pause and make an appointment from the last 1-5 letters I've typed. The program the proceeds and I can continue typing the message - although it may happen again during completion.

I have uninstalled and reinstalled Outlook 2016
I have deleted all profiles and created new ones.
The issue continues.
OS = Win10 (10.0.16299.98)

Any thoughts or ideas on how to resolve this issue would be Greatly appreciated! TIA!!

 

Hahaha, I wish it were that easy!
I type pretty well, actually, and CTRL-ALT-A is not an easy combo for one hand. And it doesn't really launch the make an appointment screen; the calendar reminder screen pops up showing the few typed letters set at an appointment time already, sometimes at that exact moment, sometimes for a future time. Very strange indeed!
