Sending, receiving, and organizing email in Outlook.com
I’m sorry you’re having trouble accessing your Outlook.com account. When it asks for a security key, do you see an option such as Other ways to sign in, Use your password, or I don’t have any of these?
Did you recently change your password, phone number, alternate email address, or other security information?
The questions about previous purchases and emails sound like Microsoft’s account recovery verification process, so it would also help to know whether you reached that form directly from a Microsoft sign-in page or from a link in an email.
Please do not post your password, verification codes, recovery codes, or full email address here.
