It would seem that I forgot to logout of my Hotmail account (on Outlook.com aka Login.live.com) on a comptuer at school.
Someone used this conenction to send unwanted e-mail.
Even though I changed the password, this other session still appears valid since the person can still send e-mail.
Can I remotely shut this session down (something similar to disconnect from everywhere) ?
You cannot invalidate the sessions remotely. However changing password helps. I am not sure how long would that take to get into effect.
