Using classic Outlook for Windows in business environments
I have the SAME PROBLEM, and it DID start when "Co-Pilot" went live.
I have 12 email accounts loaded into Outlook. I'm locked out of at least one of my accounts, the second that tried to load yesterday after I was out of the country and away from my desktop PC for 4 months, but I can't get past the blank screen that should let me reset the email's password (AGAIN). I have no idea how many of my emails are unusable.
Computers. The great time savers.
