Steven F, original poster here: my Outlook just fixed @ 1:20 Pm pst, I tried it and it opened right up. Hope the same for all of you, maybe 1 at a time! Thanks all.......

Same issue here - I've tried Office repair 3x - rebooted. This occurred after recent Windows update last night.

See solution here - worked for me - rolled back to previous version - that was easy - only took 3 hrs to fix 🙂

This works. I've rolled back two machines and Outlook functionality is restored.
