I did a number of searches through the forums and google, but found no information on this.

The problem is:
I have an Android user who is attempting to use a third party mail app called "K-9 Mail"
The option for exchange in his app is listed as "Exchange (WebDAV)," after selecting this option, entering the users information, I am prompted to download the certificate, then the app returns "Cannot connect to server. (IOException)" After doing some research I found that this is most likely because I don't have WebDAV enabled.

The question is:
Does Data Sync have the capability of using the WebDAV protocol? If so, where do I activate it?
