Hello, I am sorry to hear the trouble. I guess you had too many unsuccessful attempts for logging in your email account at Outlook. Is it true?
Sorry! You message just appeared on my side!
As I got your full email address, do you mind I test it and try recovering it from my side now?
You mean you have no issue to access your email Outlook mailbox, the issue is you can't use this address to log in for your Office 365 subscription. Is it correct?
What's the exact error message? A screenshot please?
Did you try this
"It looks like your account has been blocked" error when a user tries to sign in to Office 365
