If you were directed to this page, it's because you tried to send an email message from your Outlook.com account after being notified that your account was temporarily blocked.
Why was my account blocked?
Outlook.com helps protect your account by looking for unusual sign-in activity and warning you via email or text message. For example, if you always sign in to Outlook.com from Safari on one computer, and you try to sign in from Internet Explorer on another computer in another country at the same time, you may receive a message warning you of unusual sign-in activity.
If your account was blocked, we apologize for the inconvenience, but this temporary blockage is an important tool to help protect against junk email and online fraud.
What should you do if you receive a warning message?
The first step you need to take to unblock your account is to change your password. Choose a strong password that contains letters, numbers, and symbols.
Once you've changed your password, you can try to unblock your account online. You'll need to request a code that will be sent to your phone via text message. If you don't have a phone that can receive text messages, or you're in a country or region that doesn't support text message validation, you'll need to contact support. To see if your region supports text message validation, see Validate my account.Unblock your account online
If you're currently signed in to your blocked account, sign out.
Go to https://account.microsoft.com, sign in to your blocked account, and follow the instructions on the page.
If you can't unblock your account online, you can contact support via an online form. In order to use this form, you must be signed in to your account. Once you fill out the support form, a Microsoft customer service representative will contact you via email within 24-hours, either with instructions on how to unblock your account or to request additional information. You'll continue to receive update emails until your account is unblocked.
