Cannot add Exchange 2010 mailbox to EMAIL options jellybean 4.1.2

I cannot add Exchange 2010 mailbox to the EMAIL options in jellybean 4.1.2.

This works fine on every other iPhone device I have setup for where I work. I'm the IT Admin and chose to go with Android for my first smartphone and now I'm having problems doing the most basic things.

The usual error I'm getting is this:
"couldn't finish
the server responded with an error. check your username and password then try again"

I have done this countless times and know that the username/password are correct, however I have seen discrepancies on the web about how these should be typed in for Android phones.

Also, when I try to add the mailbox to EMAIL on the phone, if I do not select "Accept all SSL certificates" I get an error stating there is something wrong with the SSL certificate. When I do select "Accept all SSL certificates" the SSL error goes away and the above server error message displays instead.

What am I doing wrong? Does my phone need to be wiped or updated or what?
