Managing personal Outlook.com account settings, security, and privacy
THANK YOU SO MUCH, this helped me to reactivate account. Didn't logged out but could reset password and after that everything worked fine.
Dear all,
in my case, I managed to do a general sign out using the option in this link: https://account.live.com/proofs/Manage/additional
After that, it went lik a charm.
It makes me tink that someone managed to hack into my accont somehow, looking back at the activity on my account, there had been recent attempts from Russia, China and the US...one wonders...
Good luck,
Ch.
