i have exchange 2013 fully working , autodiscover is working fine as well.
my problem is with mobile devices asking for username , domain , password .... when trying to configure the email accounts.
i have added the \ and domain under basic aut setting in iis .
this is working only when the email address name is the same as the user name login name in AD
let say that my email is firstname.lastname@example.org the settings are getting completed.
if my email is email@example.com i need to provide the missing setting , domain , password , username...
thanks in advance.
