Sending, receiving, and organizing email in Outlook.com
@Huw Griffiths said
Over the last few months I have repeatedly received the same automated message when attempting to login: 'You've tried to sign in too many times with an incorrect account or password'
Many, many, many other users are facing the same problem. No official word from Microsoft on the cause or when it might be fixed.
A few suggestions:
1 -- Add another sign-in method. As suggest by Kim Otterson, add one or more other ways to sign-in besides a password. At least an alternate email address and perhaps a passkey.
2 -- The problem could also be caused by someone trying to repeatedly access your account and failing. i.e. They know your email and are trying different passwords to see if one works.
You can setup a Login Only Alias and disable Sign-In for your current email address. Then, if all the Bad Guys have is your email alias, they get "This username has been turned-off for sign in" at the very first step of the logon process and can not continue.
