I have someone for whom I've done custom scripting work write to me over the last several days saying the scripts that had been fine for well over a year now suddenly stopped working. The version where they stopped working: Microsoft Outlook Subscription Version 16.0.12527.20242
Rolling back to Microsoft Outlook Subscription Version 16.0.12527.20194 brought 'em back to life.
I have actual, locally installed, Office 2016 which includes Outlook. Office 365, while sharing a lot of DNA with Office 2016 and 2019, is still a different animal that could have different bugs introduced.
When I go into the File Tab, Office Account Tab, and look under About Outlook it says that it's on Version 2002 (Build 12527.20242 Click-to-Run). My Office is Office Professional Plus 2016.

Tolerance is the positive and cordial effort to understand another's beliefs, practices, and habits without necessarily sharing or accepting them.
