Welcome to our Community Forums! Thank you for your first post. I'm sorry to hear that you're experiencing some issues with your mailbox at the moment!
I can see that @Graham_A shared a link with you to follow the instructions on what to do in this situation. Can you tell us if this helped at all? Are you able to reset your password to something new by following the Forgotten Password option and change your password to something completely new and never used before? Once you've done this, please wait at least 10 minutes for this to update on our system and then see if you have access to your mailbox again.
