Answer 1

Приведенный ниже код работает для отправки или сохранения черновика электронной почты.

static void CheckEmail()
{
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);
service.Credentials = new WebCredentials(senderEmailId, password);
 service.AutodiscoverUrl(senderEmailId, RedirectionUrlValidationCallback);

 EmailMessage emailMessage = new EmailMessage(service);
 emailMessage.Subject = "Test office 365 project draft ";
 emailMessage.Body = new MessageBody("Testing Exchange Web Service API");

 emailMessage.ToRecipients.Add(emailTo);

//send email
emailMessage.Send();

//save to draft
emailMessage.Save(WellKnownFolderName.Drafts);
}

   private static bool RedirectionUrlValidationCallback(string redirectionUrl)
    {
        // The default for the validation callback is to reject the URL.
        bool result = false;

        Uri redirectionUri = new Uri(redirectionUrl);

        // Validate the contents of the redirection URL. In this simple validation
        // callback, the redirection URL is considered valid if it is using HTTPS
        // to encrypt the authentication credentials. 
        if (redirectionUri.Scheme == "https")
        {
            result = true;
        }
        return result;
    }
