Using Classic Outlook on Windows for personal email, calendar, and contact management
From Carl Katz:
This worked for me. Close all Office apps. Then open CMD with elevated permissions (as administrator) and use this command:
“C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe” /update user updatetoversion=16.0.17029.20108 Note you will need to stop getting updates until they fix it. Alternatively move to the semi annual enterprise channel
