We are running Exchange 2010. We have changed our external DNS from x.com to y.com
How do I change the iPhone Activesync authentication to recoginize name@y.com as new credentials? Only recoginizes original DNS x.com
We own both external DNS's. I have set y.com as the default sending domain. I think this is DNS autodiscover issue? Do i create a new zone for y.com? Any ideas what i need to do?
