Hi
Recently we introduced Exchange 2013 servers to our existing Exchange 2007 organization. The servers are just configured with default self-signed certificate and URLs are pointing to server FQDNs. Everything is at default as far as configuration is concerned in Exchange 2013.
After just introducing the Exchange 2013 CAS servers was checking the ActiveSync functionality using a new mailbox created on Exchange 2013. We have not yet published our Exchange 2013 servers to Internet (before even doing that, want to ensure ActiveSync is working). We're connecting using our Private network and trying to make a connection to CAS FQDN. Checked a iOS7 (iPad) and a Windows Phone device, both of them configure successfully (with the certificate warning, which is obvious) but when it comes to synchronizing the contents they fail saying "Cannot Get Mail. Connection to Server Failed"
Checked the IIS Logs on CAS server and found that the device makes a successful connection - as is indicated by successful configuration but thereafter nothing happnes on the device and no error logged in Event Viewer as well. Could it be that the mailbox server is denying the connection....how to check. How to go ahead with the troubleshooting.
Everything else expect ActiveSync is working perfectly. Tries accessing the ActiveSync VD using the linkHTTPS://Server_FQDN/Microsoft-Server-ActiveSync, this pops-up a window asking for credentials – which is normal behavior indicating ActiveSync virtual directory is good.
Thanks
