If yes, there is an ongoing issue with Microsoft server that affected the connection or authentication between Outlook and other services. Microsoft has already aware with this situation and actively monitoring and currently working to resolve this issue as quickly as possible.
If not, would you mind please tell me what the exact error message is or is there any error code when you sign in? You can also take a screenshot and attach in the comment below so I can take a better look
Looking forwards to your response.
