with your RPC Proxy setting on the client do you have BASIC authentication configured for the Exchange over HTTP settings.

So long as you have a SSL certificate BASIC authentication should be acceptable.

so in the account settings on the client goto Advanced then to Connection and the RPC Proxy settings are there.

There is another authentication method that is not on the proxy settings page, Leave it set for NTLM
Could you the Exchange Test Connectivity website to verify the autodiscover features?

Pity neither poster above actually read your question.

To make ActiveSync work internally and externally you need to do two things.

1. Setup a Split DNS system so that the external name resolves internally.
This is quite easy and I have documented how here:

2. Change the ActiveSync internal URL to match the external URL.

You should run IISRESET from an elevevated command prompt after doing so.

Once you have done that, test again.

The error you have posted is very generic and doesn't really help with troubleshooting. Ensure that the account you are testing with is a test account that is not an Administrator.

Has it ever worked?
