Built two new virtual 2012 R2 servers, then promoted them both to domain controllers. My 2003 SP2 Domain Controllers are still up an running normally on my network. All went perfect last night, then this AM we noticed we were not getting email pushed down to our iPhones. Some users are getting a cannot connect to server message and some users such as myself are just not getting the new emails.
We have a 2003 domain, 2 - 2003 domain controllers (DNS, AD), 1 - 2003 Exchange server, 1 - 2003 OWA Exchange server (running in a DMZ). We use our OWA website to connect the iPhones to the email. I can log into OWA via IE just fine, it is just no email on the iPhones.
I have been searching this site for answers and am not finding the info I need, so decided to ask here. All our email is functioning properly, just active sync is not. Any suggestions? Thanks.
