Dear Marc Leclerc1
Thank you for posting in Microsoft Community.
Based on your description, I know you face some problems on outlook
but you've provided so little information that I can't tell if the problem you're experiencing is one within the other. Please let me ask a few questions to better troubleshoot your problem.
Are you a personal or business user? If a business user, what is your domain name?
Can you provide a screenshot of the error you're reporting?
Please answer these questions so I can better pinpoint your problem and help you!
From my experience, I see that you turned on to 2-step verification, you can try it based on my image below , enter the new code
If you have any questions, please contact us and we will get back to you as soon as possible!
Thank you for your understanding and cooperation.
Best Regards ,
