Use the ResolveName("SMTP:") API to retrieve all the contacts from Global Address List, the limitation of such is it only returns the top 100 from the query operation.

Your Managed EWS code works similar to 

        var nameResolutionCollection = service.ResolveName("SMTP:");
        foreach(var item in nameResolutionCollection)
        {
            // your code in here
        }
