Hello Ron TF
I am very sorry to hear about the situation you are experiencing. I understand how frustrating it must be to be unable to access your email.
Based on the information you provided, this issue may be caused by a temporary error on Microsoft servers affecting the connection or authentication between Outlook and Hotmail. Microsoft is already aware of the situation, is actively monitoring it, and is working to resolve the issue as quickly as possible.
Many other users are reporting the same problem:

Since the root cause lies on the server side, we recommend waiting approximately 24 to 48 hours before attempting to log back into your Hotmail account.

We appreciate your patience and understanding.
