I'm sending emails via a shared mailbox using the MS Exchange Web Services API.

Sending emails works but they are not saved in the sent items. As shown below doing it manually works, the items are saved in the Sent Items, but via my code doesn't save them:

using Microsoft.Exchange.WebServices.Data;

using System;



//Ref to Microsoft.Exchange.WebServices  v15

//Re to Microsoft.Exchange.WebServices.Auth  v15



namespace Emailing

{

    public class Email 

    {

        private string _sharedOutlookMailAccount = "aSharedEmailAccount@something.com";        

        private ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP2);



        public Email(string exchangeURL = "https://webmail.something.com/ews/exchange.asmx")

        {

            try

            {

                exchangeService.AutodiscoverUrl(_sharedOutlookMailAccount);

                //exchangeService.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, _sharedOutlookMailAccount);



                exchangeService.UseDefaultCredentials = true;

            }

            catch (System.Runtime.InteropServices.COMException ex)

            {

                //...

            }

            catch (Exception ex)

            {

                //...

            }

        }



        public bool SendEmailFromSharedMailBox(string emailTo, string emailCc, string emailBcc, string emailSubject, string emailBody, string emailFileAttachments, bool emailFromSharedMailbox = false, bool sendToDraftOnly = false)

        {

            EmailMessage message = default(EmailMessage);

            message = new EmailMessage(exchangeService);



            emailTo = emailTo.TrimEnd(';', ',');

            string emailArr = emailTo.Split(';', ',');

            if (emailTo.Length > 0) message.ToRecipients.AddRange(emailArr);



            emailCc = emailCc.TrimEnd( ';', ',' );

            emailArr = emailCc.Split(';', ',' );

            if (emailCc.Length > 0) message.CcRecipients.AddRange(emailArr);



            emailBcc = emailBcc.TrimEnd(';', ',');

            emailArr = emailBcc.Split(';', ',');

            if (emailBcc.Length > 0) message.BccRecipients.AddRange(emailArr);



            #if DEBUG

                emailSubject = "IGNORE - TESTING ONLY - " + emailSubject;

            #endif



            message.Subject = emailSubject;



            EmailAddress fromSender = new EmailAddress();

            fromSender.MailboxType = MailboxType.Mailbox;

            fromSender.Address = _sharedOutlookMailAccount;

            message.From = fromSender;



            if (emailFileAttachments != null)

            {

                foreach (string fileAttachment in emailFileAttachments)

                {

                    if (string.IsNullOrEmpty(fileAttachment) == false)

                        message.Attachments.AddFileAttachment(fileAttachment);

                }

            }



            message.Sensitivity = Sensitivity.Private;

            message.Body = new MessageBody();

            message.Body.BodyType = BodyType.HTML;

            message.Body.Text = emailBody; //+= "_sharedMailSignature";



            //Save the email message

            try

            {

                //THIS WORKS AND IS REQUIRED FOR THE Send() &/or SendAndSaveCopy() METHODS TO WORK

                message.Save(new FolderId(WellKnownFolderName.Drafts, _sharedOutlookMailAccount));

            }

            catch (Exception ex)

            {

                //...

                return false;

            }



            if (!sendToDraftOnly)

            {

                try

                {

                    //==================================================================

                    //THIS SENDS EMAILS BUT THEY ARE NOT SAVED IN THE SENT ITEMS!

                    //==================================================================

                    message.SendAndSaveCopy(new FolderId(WellKnownFolderName.Drafts, _sharedOutlookMailAccount));

                }

                catch (Exception ex)

                {

                    //...

                    return false;

                }

            }

        return true;

    }

}

Does anyone know how I can save the sent emails into the Sent Items folder?

I needed to use WellKnownFolderName.SentItems not Drafts.

  message.SendAndSaveCopy(new FolderId(WellKnownFolderName.SentItems, _sharedOutlookMailAccount));

Other causes/resolutions for this issue are described in this Microsoft Knowledge Base (KB) Article:

Yes, you can use the SendAndSaveCopy function to achieve your needs. Here is an official document about EWS API.
