Thank you for your response Ingo.
I had tried userPrincipleName in the mail field, and while I could return the correct names, there was no option to add the username.
However, using sAMAccountName and appending the domain in the mail suffix field does return the correct format for adding contacts.
Looking back I probably should have tried that, but perhaps I was too close to the problem. Thanks for the help.
Now I just need to provision those settings to the users.
