Summary:
I am having trouble connecting to an exchange 2007 mailbox that is running FBA with my C# code using webdav.
Details:
This code below has to work against an exchange 2007 server, connect, and read email from a mailbox.
I've tried EWS but it made no sense and I couldn't get it working.
Below is my code. I am using the outlook url to get the cookies I need to login via webdav to the exchange url.
Error:
440 login timeout on the request.
Area where my code breaks:
Response = (HttpWebResponse)Request.GetResponse();
Code:
namespace logintomailbox
{
class Program
{
#region auth dont exapnd
