Connect to Exchange email with windows authentication

Question

Its possible to connect to Exchange email box with windows authentication ? I cant have password in the program because of security compliance. If yes, how? Thank you.

working solution

• download: EWS Management API 2.1 http://www.microsoft.com/en-us/download/details.aspx?id=42022
• add assembly to reference: C:\Program Files (x86)\Microsoft\Exchange\Web Services\2.1\Microsoft.Exchange.WebServices.dll
• switch project to .NET framework 3.5 (im not really sure if this is a must)

code

using Microsoft.Exchange.WebServices.Data;
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.UseDefaultCredentials = true;
service.AutodiscoverUrl("username@domain.tld");

Answer 1

If you use ExchangeServiceBinding class from Exchange Web Services you have UseDefaultCredentials property. Setting this to true will make the authentication use the current user.
