I have a HTC Touch Pro from Sprint. About one week ago, my exchange server started acting up. While my phone is plugged into my computer via USB cable, or connected to a WiFi network, it syncs just fine with my exchange server. However when trying to sync over the air (Sprint Data Network) it fails with the Error Code of 0x80072EE2. It does not matter whether I plug the phone into the computer first, or not. In general, over the air does not work.
Occasionally it will work over the air for a few hours, but then it will go back to the same old error above.
I have followed Microsoft's support regarding this error in changing the DnsCacheEnable to 0, with no resolution. Any other help would be great. Thanks.

Check the proxy settings on the device. Mine had picked up the proxy server that was set on my laptop for the corporate network and was trying to use it when syncing over Verizon's broadband connection. Once I reconfigured the appropriate connection on the 700w not to use a proxy server, this error was resolved.
