email setup in black berry with custom domain

I am using domains.live.com for email accounts for my custom domain. I am trying to set it up with my blackberry but i am unable to do so. 

I am getting stuck with the following:

On entering email server as m.outlook.com i am getting the following error : "Please verify your email account information. The information you provided is incorrect"

Please suggest on what needs to be done.

Thanks
