I am a sophomore student working in the ID Office and Residence Life. So I don't exactly work in IT or anything but I'll try to help.
When I set up my MSOE email it was a combination of my first and last name. For example, if "Fred Jobes" had an MSOE email it would probably be "email@example.com". For you, "firstname.lastname@example.org" is most likely your email. When you first log onto your email, you have to use a default password that IT sets up for you. Your default password is your ID number with your birthday (mmddyy). At least that was what it was when I started school here.
If what I suggested doesn't work I would contact our IT department at (414)277- 7288. They would probably be more helpful than me.
