Using Classic Outlook on Windows for personal email, calendar, and contact management
I have the same problem as of this morning 8/19/2020 outlook will not open. It is not running on the task manager.
Mine would not open for two weeks, I had to go in through internet to check emails, but i am totally lost without contacts in outlook. Outlook opened for me one day just out of the blue when i turned on my laptop. I leave it open now all the time, so far its been fine for a week. Try doing what Hal proposed since it worked for Angela and let me know. I figure any day it could close and not open again until they have put in a permanent fix.
