While you activated O365 service according to activating guidelines, the system created a new email address for you and showed it on the screen. The email address is usually as a rule:

firstname.lastname(at)student.oulu.fi

But if there exists an other user with the same name, your address could contain letters from your second name or numbers. So your email address could be in form:

firstname.x.lastname(at)student.oulu.fi
 

• Inform all partners in cooperation including library and email lists about your new email address.
• Update your email address in information services you are using. For example WebOodi, read QuickGuide to update personal data in WebOodi.
• Emails sent to this address will come into O365 service.

The username of O365 service is a valid email address too:

account(at)student.oulu.fi

Also these old forms of email addresses can still be used:

account(at)paju.oulu.fi

account(at)mail.student.oulu.fi
 

• Messages sent to these addresses will be automaticly forwarded into O365 service.
• You can read messages sent to these addresses in O365 service.
