Hi all, Well I found an example: here[^], but I keep receiving an exception, more specifically: On this line of code: WebDavResponse = (System.Net.HttpWebResponse)WebDavRequest.GetResponse(); Exception: WebException Description: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. Any ideas how I can fix this? Many thanks again. Kind regards,

When requesting to https, you need to add a certificate with the request. Add that to ClientCertificates collection of request object. To query exchange server and get all mails from inbox, you could do something like

string serverUrl = "https://yourdomain.com/exchange/userid/inbox/"
const string xml = "<?xml version='1.0'?>" +
"<g:searchrequest xmlns:g='DAV:'>" +
"<g:sql>{0}</g:sql>" +
"</g:searchrequest>";

string query = "SELECT * FROM SCOPE('SHALLOW TRAVERSAL OF \"" + serverUrl + "\"') " + "WHERE \"DAV:isfolder\" = false";
string requestString = string.Format(xml, query);

WebHeaderCollection headers = new WebHeaderCollection();
headers.Set("Pragma", "no-cache");
headers.Set("Translate", "f");
headers.Set("Depth", "0");

WebDavRequest.Method should be SEARCH. Set the WebHeaderCollection to WebDavRequest.Headers property. I have written a useful WEBDAV wrapper for one of our application. I can share as an article later :)

Hmmm ... this sounds like the difficult part ...

Hi Navaneeth, Now I keep receiving the following error message, could it be that the WebDav is disabled on the exchange server? The remote server returned an error: (440) Login Timeout. Thanks again. Kind regards,

Not sure. I haven't experienced this so far. All I can suggest is to try adding more timeout value.
