I have been reading the posts trying to resolve issue with iPhone. We have 4 employees with them 2 phones work fine with Exchange and Outlook. The other 2 setup fine but then cannot receive emails. Folders are all there just won't connect to server. Why??? I found some other question/answers on here. Ran one of the tests but don't know what to do now.
Testing Exchange ActiveSync
Exchange ActiveSync test Failed
Attempting to resolve the host name mail.lease-sped.org in DNS.
Host successfully resolved
IP(s) returned: 188.8.131.52
Testing TCP Port 443 on host mail.lease-sped.org to ensure it is listening and open.
The specified port is either blocked, not listening, or not producing the expected response.
Tell me more about this issue and how to resolve it
A network error occurred while communicating with remote host
Message: No connection could be made because the target machine actively refused it 184.108.40.206:443
at System.Net.Sockets.TcpClient.Connect(String hostname, Int32 port)
Do I need to open this port and if so how? Why does it work fine for half the phones (identical and updated software wise). Any help greatly appreciated.
