    I also face the same issue for my hotmail.com e-mail address (not only for my outlook.com e-mail address).

    I still can enter the account under account.live.com, but I am not able to open them in Outlook.

    I also tried incognito mode, new browser, but nothing helped. I removed my hotmail account from outlook and wanted to add it again, but this is also not working anymore.

    The issue started with the fact that outlook asked always and always again for a password of my email address which was properly set-up a long time ago.

    Même problème sur un de mes comptes (le plus important en plus). J'ai besoin de savoir quand cela sera réglé pour prévenir mes clients et commanditaires.
