Hello,
We currently have about 5 iPhone connected to our Exchange 2010 Server and recently we are all recieving the error message, cannot to connect to server
A little more background on recent events with the server:
Our IP address was recently changed by our service provider that caused a lot of issues and we were unable to recieve any external emails - This is now functioning properly after updating our dyndns account
We are unable to access our remote access web portal for sbs 2011 from external internet connections
We can recieve mail just fine if connected to wifi at the office this send recieve issue is only happening on 3G connections and other wifi networks
Thanks and if I can provide anymore information I will try my best
