How to revoke access for trusted devices on outlook.com after having changed the password

You should perform a virus scan on your computer. The chances of a hacker sending random emails on your account is very slim. More than likely, the link you clicked performed a drive-by download and loaded malware on your computer. If the malware sent the same link you clicked to all your contacts, you should tell them to immediately scan their computer for viruses if they clicked it.

I figured this out, but I wanted to post this here so others can learn. I could not find a good FAQ or help page to explain this.

I changed my password using the Hotmail.com web site last night. For good security, I selected a long password of 19 characters. Logging in from the web worked fine, but when I tried to update my password on my mobile devices I got invalid password error. I tried Exchange protocols and Pop3 protocols and the Microsoft Android Hotmail application. None worked with the new password.

I found a few articles today that described similar problems. These included

In these forums people mentioned that Pop3/Exchange access to Hotmail may require shorter passwords than web access. I changed my password to a 12 character string and then I was able to successfully log in from my mobile devices.

So, be careful of your password length on Hotmail if you use Pop3 or Exchange to access your email.
