Retrieve Alias From SharedMailbox

I would like to retrieve the alias email that would have been emailed to a Shared Mailbox but Exchange overrides the "To recipient" with the Primary email address of the shared mailbox
Example - "aa#alias.co.uk" Alias is emailed on the shared mailbox. I would like to retrieve the "aa#alias.co.uk" email
PrimaryEmail - aa#primarydomain.co.uk
Alias Email - aa#alias.co.uk
I have tried accessing the headers of the email but, no luck
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Exchange.WebServices.Data;
namespace readSharedMailbox
{
class Program
{
static void Main(string[] args)
{
ExchangeService _service;
try
{
Console.WriteLine("Registering Exchange connection");
_service = new ExchangeService
{
Credentials = new WebCredentials("*******", "********")
};
}
catch
{
Console.WriteLine("new ExchangeService failed. Press enter to exit:");
return;
}
// Office365 webservice URL
_service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
try
{
Console.WriteLine("Reading mail");
FindItemsResults<Item> result = _service.FindItems(WellKnownFolderName.Inbox, new ItemView(1));
foreach (Item item in result)
{
EmailMessage message = EmailMessage.Bind(_service, item.Id);
Console.WriteLine("Reading items");
Console.WriteLine(message.ToRecipients[0].Address.ToString());
/* Reading the Header
foreach (var property in message.InternetMessageHeaders)
{
Console.WriteLine(property.Name);
Console.WriteLine(property.Value);
}
*/
}
Console.WriteLine("Exiting");
Console.ReadLine();
}
catch (Exception e)
{
Console.WriteLine("An error has occured. \n:" + e.Message);
}
}
}
}

Exchange always resolves the sender and recipients to their GAL objects - you no longer have one-off SMTP entries, but GAL objects. Retrieving the PR_TRANSPORT_MESSAGE_HEADERS property (DASL name http://schemas.microsoft.com/mapi/proptag/0x007D001F) and manually parsing the To/CC headers is the only way to see the original SMTP address that the message was sent to. But even then, I have seen cases when the MIME headers were mangled by Exchange and no longer contained SMTP addresses, just the display names.

C# Saving Exchange .EML file from within Windows Service

I'm currently writing a Windows Service to log in to a specific Exchange account, get any new emails, parse them, and save the email in the appropriate folder.
Everything is working perfectly, except saving the email.
Relevant code blocks (try / catch blocks and irrelevant stuff removed to keep it short):-
Set up the Service
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials(emailAddress, password);
service.AutodiscoverUrl(emailAddress, RedirectionUrlValidationCallback);
CheckForNewEmails(service);
Getting and checking new emails
private static void CheckForNewEmails(ExchangeService service)
{
int offset = 0;
int pageSize = 50;
bool more = true;
ItemView view = new ItemView(pageSize, offset, OffsetBasePoint.Beginning);
view.PropertySet = PropertySet.IdOnly;
FindItemsResults<Item> findResults;
List<EmailMessage> emails = new List<EmailMessage>();
while (more)
{
findResults = service.FindItems(WellKnownFolderName.Inbox, view);
foreach (var item in findResults.Items)
{
emails.Add((EmailMessage)item);
}
more = findResults.MoreAvailable;
if (more)
{
view.Offset += pageSize;
}
}
if (emails.Count > 0)
{
PropertySet properties = (BasePropertySet.FirstClassProperties);
service.LoadPropertiesForItems(emails, properties);
var mailItems = new List<DatabaseService.MailItem>();
var dbService = new DatabaseService();
var defaultUser = dbService.GetDefaultUser(defaultUserID);
foreach (var email in emails)
{
var mailItem = new DatabaseService.MailItem();
mailItem.mail = email;
mailItem.MessageID = email.InternetMessageId;
mailItem.Sender = email.Sender.Address;
dbService.FindLinks(service, ref mailItem, defaultUser);
mailItems.Add(mailItem);
LogMessage += (string.Format("Message ID : {1}{0}Sent : {2}{0}From : {3}{0}Subject : {4}{0}Hash : {5}{0}{6}{0}{0}", Environment.NewLine,
mailItem.MessageID ,
email.DateTimeSent.ToString("dd/MM/yyyy hh:mm:ss"),
email.Sender,
email.Subject,
mailItem.Hash,
mailItem.LinkString
));
}
}
}
Finding who it should be linked to
public void FindLinks(ExchangeService service, ref MailItem mailItem, User defaultUser)
{
string address = mailItem.Sender;
// get file hash
var tempPath = Path.GetTempPath();
var fileName = GetFilenameFromSubject(mailItem);
var fullName = Path.Combine(tempPath, fileName);
SaveAsEML(service, mailItem, fullName);
var sha = new SHA256Managed();
mailItem.Hash = Convert.ToBase64String(sha.ComputeHash(File.OpenRead(fullName)));
File.Delete(fullName);
using (var db = DatabaseHelpers.GetEntityModel())
{
// Do all the linking stuff
}
}
And finally, the problem area: Saving the file to disk (in this case to a temporary folder so I can get the file hash, to check it's not a duplicate (e.g. CC'd etc))
Looking through StackOverflow and various other sources, there seem to be two ways to do this:-
1) Using the MailItem.Load method
private string SaveAsEML(ExchangeService service, MailItem mailItem, string savePath)
{
using (FileStream fileStream = File.Open(savePath, FileMode.Create, FileAccess.Write))
{
mailItem.mail.Load(new PropertySet(ItemSchema.MimeContent));
fileStream.Write(mailItem.mail.MimeContent.Content, 0, mailItem.mail.MimeContent.Content.Length);
}
}
Using the above code, the file is created and has the correct content.
However, attempting to access any of the email properties AFTER this point results in a Null Exception crash (big crash too, no Try/Catch or UnhandledException trap will pick it up, just kills the Service)
In the above code, this line crashes the entire service:-
LogMessage += (string.Format("Message ID : {1}{0}Sent : {2}{0}From : {3}{0}Subject : {4}{0}Hash : {5}{0}{6}{0}{0}", Environment.NewLine,
mailItem.MessageID ,
email.DateTimeSent.ToString("dd/MM/yyyy hh:mm:ss"),
email.Sender,
email.Subject,
mailItem.Hash,
mailItem.LinkString
));
Specifically, referencing email.DateTimeSent
I added in some diagnostic code directly before this line:-
if (email == null) { Log it's null; } else { Log NOT null;}
if (email.DateTimeSent == null) { Log it's null; } else { Log NOT null; }
The first line logs NOT null, so email still exists.
However, the second line instantly crashes with a null exception error, without logging anything.
If I comment out the line SaveAsEML(service, mailItem, fullName); from FindLinks then everything works perfectly (except of course the file isn't saved).
2) Binding a Property Set
private string SaveAsEML(ExchangeService service, MailItem mailItem, string savePath)
{
using (FileStream fileStream = File.Open(savePath, FileMode.Create, FileAccess.Write))
{
PropertySet props = new PropertySet(EmailMessageSchema.MimeContent);
var email = EmailMessage.Bind(service, mailItem.mail.Id, props);
fileStream.Write(mailItem.mail.MimeContent.Content, 0, mailItem.mail.MimeContent.Content.Length);
}
}
Doing it this way, nothing crashes, it goes through every email just fine, and can reference email.DateTimeSent and all the other properties.
Unfortunately, it creates zero-length files, no content.
Been banging my head against the wall for hours now over this (took me an hour of adding diagnostics everywhere just to track down the crash happening when referencing properties), and it's undoubtedly something trivial I've overlooked, so if some kind soul could point out my stupidity I'd be most grateful!
Edit:
I was able to work around the above problem easily enough by simply saving the value of the properties before using them:-
foreach (var email in emails)
{
var dateTimeSent = email.DateTimeSent;
var sender = email.Sender;
var subject = email.Subject;
var mailItem = new DatabaseService.MailItem();
mailItem.mail = email;
mailItem.MessageID = email.InternetMessageId;
mailItem.Sender = email.Sender.Address;
dbService.FindLinks(service, ref mailItem, defaultUser);
mailItems.Add(mailItem);
LogMessage += (string.Format("Message ID : {1}{0}Sent : {2}{0}From : {3}{0}Subject : {4}{0}Hash : {5}{0}{6}{0}{0}", Environment.NewLine,
mailItem.MessageID,
dateTimeSent.ToString("dd/MM/yyyy hh:mm:ss"),
sender,
subject,
mailItem.Hash ?? "No Hash",
mailItem.LinkString ?? "No Linkstring"
));
}
This allowed me to use the MailItem.Load method which saved the file, and thus do what I was after in this specific case.
However there are other things this Service will need to do, and I really don't want to have to save a copy of every single property I'll need to access.

The reason this would fail
private string SaveAsEML(ExchangeService service, MailItem mailItem, string savePath)
{
using (FileStream fileStream = File.Open(savePath, FileMode.Create, FileAccess.Write))
{
PropertySet props = new PropertySet(EmailMessageSchema.MimeContent);
var email = EmailMessage.Bind(service, mailItem.mail.Id, props);
fileStream.Write(mailItem.mail.MimeContent.Content, 0, mailItem.mail.MimeContent.Content.Length);
}
}
Is that you have used Bind to Load the message with the MimeContent in the email variable and then you haven't used that. mailItem.mail won't be linked at all to email variable created as part of this operation (even though they are the same object on the server). Locally these are just two separate variables. EWS is client/server so you make a request and the Managed API will return a local object that represents the result of the operation. But that object is disconnected hence when you do the bind above it just generates another client object to represent the result of that operation. eg so the above should have been
private string SaveAsEML(ExchangeService service, MailItem mailItem, string savePath)
{
using (FileStream fileStream = File.Open(savePath, FileMode.Create, FileAccess.Write))
{
PropertySet props = new PropertySet(EmailMessageSchema.MimeContent);
var email = EmailMessage.Bind(service, mailItem.mail.Id, props);
fileStream.Write(email.MimeContent.Content, 0, email .MimeContent.Content.Length);
}
}

C# - First step with Amazon MWS

I'm an Amazon FBA seller and I would like to begin to upload data regarding my sales in a more automated process using Amazon MWS. I just made an amazon MWS account and received my different IDs (Access Key Id, secret Access Key, ...).
I have the impression that most MWS developers use C#. I have a lot of Excel VBA experience but not in C#. Therefore, I'm not sure of the steps I have to follow.
On the webpage below, you can find a C# code that I would like to run:
http://www.samswiches.com/2011/02/how-to-use-amazon-mws-to-download-unshipped-order-reports/
Could you confirm the steps below are correct? :
1) Download Visual Studio => Do I need to download any extra package from Amazon?
2) In Visual Studio: File => New Project => C# console application
3) Erase all code and replace it by a copy-paste of the code found on above website => Do I need to put the code Inside something like "Sub - end Sub" in VBA?
4) Change "YourSecretKey", "YourSecretAccessKey", "YourSecretAccessKey", "YourMerchantID", "YourMarketplaceID" by my IDs.
5) Hit the run button
If it works, what will be the output like: An array inside Visual studio? A text file? A csv file? Where will it be stored?
I realize this is a very newbie question. However, I think that once I have a first code running correctly, my VBA experience will allow me to start efficiently from there.
Thanks in advance,
Diego.

After looking the code from http://www.samswiches.com/2011/02/how-to-use-amazon-mws-to-download-unshipped-order-reports/
I tried and changed something, and it works. Here is my solution:
Download the C# MWS Reports API Client Library: https://developer.amazonservices.com/doc/bde/reports/v20090101/cSharp.html
Use Visual Studio to create a project to get reports using MWS Reports API Client Library
Here is the code.
using System;
using System.Xml.Serialization;
using System.Collections.Generic;
using MarketplaceWebService;
using MarketplaceWebService.Mock;
using MarketplaceWebService.Model;
using System.IO;
using System.Threading;
public void testReport()
{
String accessKeyId = "Your Access Key ID";
String secretAccessKey = "Your Secret Access Key";
const string merchantId = "Merchant ID";
const string marketplaceId = "Marketplace ID";
MarketplaceWebServiceConfig config = new MarketplaceWebServiceConfig();
config.ServiceURL = "https://mws.amazonservices.com";
const string applicationName = "ApplicationName";
const string applicationVersion = "0.01";
MarketplaceWebServiceClient service =
new MarketplaceWebServiceClient(
accessKeyId,
secretAccessKey,
applicationName,
applicationVersion,
config);
RequestReportRequest reportRequestRequest = new RequestReportRequest();
reportRequestRequest.Merchant = merchantId;
// you can change ReportType here:
//http://docs.developer.amazonservices.com/en_IN/reports/Reports_ReportType.html
reportRequestRequest.ReportType = “_GET_FLAT_FILE_ACTIONABLE_ORDER_DATA_";
RequestReportResponse requestResponse = service.RequestReport(reportRequestRequest);
IdList lstRequestID = new IdList();
lstRequestID.Id.Add
(requestResponse.RequestReportResult.ReportRequestInfo.ReportRequestId);
GetReportRequestListRequest reportRequestListRequest = new
GetReportRequestListRequest();
reportRequestListRequest.Merchant = merchantId;
reportRequestListRequest.ReportRequestIdList = lstRequestID;
List<ReportRequestInfo> myListzz = new List<ReportRequestInfo>();
GetReportRequestListResponse reportRequestListResponse = new
GetReportRequestListResponse();
reportRequestListResponse =
service.GetReportRequestList(reportRequestListRequest);
GetReportRequestListResult reportRequestListResult = new
GetReportRequestListResult();
reportRequestListResult =
reportRequestListResponse.GetReportRequestListResult;
myListzz = reportRequestListResult.ReportRequestInfo;
if (myListzz.Count > 0)
{
while (myListzz[0].ReportProcessingStatus.ToString() != "_DONE_")
{
Console.WriteLine("Waiting for Report");
Thread.Sleep(61000);
reportRequestListResponse =
service.GetReportRequestList(reportRequestListRequest);
reportRequestListResult =
reportRequestListResponse.GetReportRequestListResult;
myListzz = reportRequestListResult.ReportRequestInfo;
}
if (myListzz[0].GeneratedReportId !=null)
{
GetReportRequest reportRequest = new GetReportRequest();
reportRequest.Merchant = merchantId;
String source = "C:\\myreport.txt";
reportRequest.ReportId = myListzz[0].GeneratedReportId;
reportRequest.Report = File.Open(source, FileMode.Create,
FileAccess.ReadWrite);
service.GetReport(reportRequest);
}
}
}

You are missing step 1b) Download the C# MWS Reports API Client Library. You may need other libraries to access other parts of the MWS API, but from a quick glance at that code above library is the main one.
Note that it refers to a lblStatus, which seems to be a label on a form, but nowhere in that post does it say anything else about that form. So step 2) probably is not a "console" style application, but a form based one, which also means, you shouldn't erase all code in step 3, but paste the code into whatever is the equivalent of a main() function (I've only ever used C and C++, but not C#, so I have no clue)

Interop Outlook - Sending Appointment from another mailbox

I have two mailboxes setup in Outlook.
I'll refer to them as "email1#mail.com" and "email2#mail.com".
I would like to use Interop to create and send an appointment to a specific email address calender, not just to the default outlook account.
using System;
using System.Diagnostics;
using System.Reflection;
using Outlook = Microsoft.Office.Interop.Outlook;
namespace Program
{
class Program
{
public static void Main(string[] args)
{
// Create the Outlook application.
Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Outlook.Account account = oApp.Session.Accounts["email2#mail.com"];
// Get the NameSpace and Logon information.
Microsoft.Office.Interop.Outlook.NameSpace oNS = oApp.GetNamespace("mapi");
// Log on by using a dialog box to choose the profile.
oNS.Logon(Missing.Value, Missing.Value, true, true);
// Create a new mail item.
Microsoft.Office.Interop.Outlook.MailItem oMsg =(Microsoft.Office.Interop.Outlook.MailItem) oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
// Set the subject.
oMsg.Subject = "test";
// Set HTMLBody.
oMsg.HTMLBody = "test";
oMsg.To = "test#gmail.com";
//oMsg.CC = _cc;
//oMsg.BCC = _bcc;
oMsg.Save();
oMsg.SendUsingAccount = account;
// Add a recipient.
//Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)oMsg.Recipients;
// TODO: Change the recipient in the next line if necessary.
//Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add(_recipient);
//oRecip.Resolve();
// Send.
(oMsg as Microsoft.Office.Interop.Outlook._MailItem).Send();
// Log off.
oNS.Logoff();
// Clean up.
//oRecip = null;
//oRecips = null;
oMsg = null;
oNS = null;
oApp = null;
}
}
}
This code works flawlessly in sending an email automatically to "test#gmail.com" from my email "email2#mail.com".
However, I would like to automatically create an appointment/meeting for a specific email address.
This is my current attempt:
using System;
using System.Diagnostics;
using System.Reflection;
using Outlook = Microsoft.Office.Interop.Outlook;
namespace SendEventToOutlook
{
class Program
{
public static void Main(string[] args)
{
try
{
// Create the Outlook application.
Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Outlook.Account account = oApp.Session.Accounts["email2#mail.com"];
// Get the nameSpace and logon information.
Microsoft.Office.Interop.Outlook.NameSpace oNS = oApp.GetNamespace("mapi");
// Log on by using a dialog box to choose the profile.
oNS.Logon(Missing.Value, Missing.Value, true, true);
// Create a new Appointment item.
Microsoft.Office.Interop.Outlook.AppointmentItem appt =
(Microsoft.Office.Interop.Outlook.AppointmentItem)
oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem);
appt.Start = DateTime.Now;
appt.End = DateTime.Now.AddDays(7);
appt.Location = "Test";
appt.Body = "Test";
appt.AllDayEvent = false;
appt.Subject = "Test";
appt.Save();
appt.SendUsingAccount = account;
// Log off.
oNS.Logoff();
appt = null;
oNS = null;
oApp = null;
}
catch (Exception ex)
{
Debug.WriteLine("The following error occurred: " + ex.Message);
}
}
}
}
This code does create an appointment successfully, but it keeps creating an appointment for "email1#mail.com" instead of "email2#mail.com", which shouldn't happen as I've specified the sending account to be "email2#mail.com" from the lines:
Outlook.Account account = oApp.Session.Accounts["email2#mail.com"];
and then
appt.SendUsingAccount = account;
This is how my two email addresses are set up in Outlook: http://i.imgur.com/0eopV8A.png
Both the email addresses have different user names and are from different domains/mail servers, as shown in that screenshot.
Would anyone be able to see the problem I'm making or if there's a different solution?
Thank you.

It is not clear whether you have got two accounts set up in the single Mail profile or separate profiles.
The SendUsingAccount property of the AppointmentItem class allows to set an Account object that represents the account under which the AppointmentItem is to be sent. So, The SendUsingAccount property can be used to specify the account that should be used to send the AppointmentItem when the Send method is called. It is not what you are looking for I suppose.
Anyway, you can use the GetDefaultFolder method of the Store class which returns a Folder object that represents the default folder in the store and that is of the type specified by the FolderType argument. This method is similar to the GetDefaultFolder method of the NameSpace object. The difference is that this method gets the default folder on the delivery store that is associated with the account, whereas NameSpace.GetDefaultFolder returns the default folder on the default store for the current profile.
Thus, you can get the Calendar folder for the required account and add a new appointment there.

EWS managed API Pull notification to watch the new email is not working

I am creating a application which will work as a window service in the back ground. This application will parse the new emails in the inbox and save the attachments. I tried streaming notification but as the connection disconnects after 30 mints I thought to use pull notifications. Below is the code which I debug but I don't see any output on console. As soon as I run the application it closes the console window so don't know if it is working. I want watch the new email as soon as it enters in the inbox so need some guidance how to achieve that.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Exchange.WebServices.Data;
using System.Configuration;
using System.Timers;
namespace PullNotification
{
class Program
{
static void Main(string[] args)
{
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
WebCredentials wbcred = new WebCredentials(ConfigurationSettings.AppSettings["user"], ConfigurationSettings.AppSettings["PWD"]);
PullSubscription SubscriptionInbox;
service.Credentials = wbcred;
service.AutodiscoverUrl(ConfigurationSettings.AppSettings["user-id"], RedirectionUrlValidationCallback);
SubscriptionInbox = service.SubscribeToPullNotifications(new FolderId[] { WellKnownFolderName.Inbox }, 5/* subcription will end if the server is not polled within 5 mints*/, null/*to start a new subcription*/, EventType.NewMail, EventType.Modified);
//Timer myTimer = new Timer();
//myTimer.Elapsed += new ElapsedEventHandler(GetPullNotifications);
//myTimer.Interval = 10000;
//myTimer.Start();
GetEventsResults events = SubscriptionInbox.GetEvents();
EmailMessage message;
foreach (ItemEvent itemEvent in events.ItemEvents)
{
switch (itemEvent.EventType)
{
case EventType.NewMail:
try
{
Item item = Item.Bind(service, itemEvent.ItemId);
if (item.Subject == "A123")
{
Console.WriteLine("check the code");
}
}
catch (Exception e)
{
Console.WriteLine("error=" + e.Message);
}
break;
case EventType.Deleted:
Item item1 = Item.Bind(service, itemEvent.ItemId);
Console.WriteLine("Mail with subject" + item1.Subject + "--is deleted");
break;
}
}
//Loop
}
internal static bool RedirectionUrlValidationCallback(string redirectionUrl)
{
//The default for the validation callback is to reject the URL
bool result=false;
Uri redirectionUri=new Uri(redirectionUrl);
if(redirectionUri.Scheme=="https")
{
result=true;
}
return result;
}
}
}

Pull notifications require that you issue a pull request (via GetEvents) when you want updates the difference between the notification methods is described in https://msdn.microsoft.com/en-us/library/office/dn458791%28v=exchg.150%29.aspx .Your code has no loop and only issue one GetItem request which is why it behaves the way you describe which is normal.
I want watch the new email as soon as it enters in the inbox so need some guidance how to achieve that.
If you want the Server to notify you when an email has arrived then you need to either look at Push or Streaming notifications Pull notifications requires that you poll the server for updates.
I tried streaming notification but as the connection disconnects after 30 mints
That's normal you just need code to reconnect and manage the subscription see http://blogs.msdn.com/b/emeamsgdev/archive/2013/04/16/ews-streaming-notification-sample.aspx for a good sample.
