Ось старий код, який я мав навколо, щоб зробити WebDAV. Я думаю, що це було написано проти Exchange 2003, але я більше не пам’ятаю. Не соромтеся позичати його, якщо це корисно ...

private CredentialCache creds = new CredentialCache();
public MailUtil()

// set up webdav connection to exchange
this.creds = new CredentialCache();
this.creds.Add(new Uri("http://mail.domain.com/Exchange/me@domain.com/Inbox/"), "Basic", new NetworkCredential("myUserName", "myPassword", "WINDOWSDOMAIN"));
}
/// <summary>
/// Gets all unread emails in a user's Inbox
/// </summary>
/// <returns>A list of unread mail messages</returns>
