Hi,
To, MSFT.
I am quite unhappy with the limited documentation on EWS. There should be many useful examples showing the power of EWS and not
just how to call a function. Also when technology is new , there should be many Videos/Writeup on troubleshooting with EWS with Steps and snapshots.
Now I am getting the following Error message and i could not find any resource which can direct me to a solution.
Microsoft.Exchange.WebServices.Data.ServiceRequestException was unhandled

InnerException:
Following is my code.
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); service.TraceEnabled = true; service.Credentials = new WebCredentials("xx@xx.com", "xxxx123"); service.Url = new Uri("https://mail.xxxxxx.com/EWS/Exchange.asmx"); FolderView v = new FolderView(5); ServicePointManager.ServerCertificateValidationCallback = RemoteCertificateValidationCallback; service.FindFolders(WellKnownFolderName.Inbox, v); //Error on above line.
I tried changing the code line as below and I get another Error ....
service.Credentials = new NetworkCredential("xx@xx.com", "xx","xxxxxxxx");
"The remote server returned an error: (401) Unauthorized."
How do i resolve. and what is difference between NetworkCredential and WebCredentials ?
