Hello.

I am trying to build a robust logic around autodsicvoer. It can fail for 3 reasons:

1) the credentials are wrong

2) the exchange server is not set up to support it

3) network error.

Is there a way to differentiate between the 3 cases using the c# api?

Looking at the code, it only throws a ServiceRemoteException when things go wrong...

Thanks, 

 Erez

No, there really isn't. The managed API encapsulates all of the Autodiscover attempts to different servers and only returns to the caller a general exception. You can enable tracing and get the information in a log file, but it sounds like you want your app to react to the different scenarios at runtime, which the general exception doesn't provide enough information to do.

Is there a way to authenticate the username/password without a URL ?

That way, if the autodiscover fails, I can prompt the user to figure out the url ,instead of re-asking "check username and password" which would be inappropriate.
