Trying to find unique id of folder in EWS C# API

I am trying to find the unique id of a folder in Outlook.
For some reason I keep getting an error with the AutoDiscoverUrl method, but I have no idea why. I have tried all the possible solutions on StackOverflow.
I am trying to run it in a commandline program using C#, and have commented/documented the code. I have used others' example on how to do this, but it doesn't work.
static void Main(string[] args)
{
// Set server binding
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.UseDefaultCredentials = true;
// Set Credentials
service.Credentials = new WebCredentials("xxxx", "xxxxx", "xxxx");
service.UseDefaultCredentials = true;
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
// Set the URL
service.AutodiscoverUrl("xxxx", Callback);
// Error Tracing
service.TraceEnabled = true;
// Redirect callback
// Set View
FolderView view = new FolderView(100);
view.PropertySet = new PropertySet(BasePropertySet.IdOnly);
view.PropertySet.Add(FolderSchema.DisplayName);
view.Traversal = FolderTraversal.Deep;
FindFoldersResults findFolderResults = service.FindFolders(WellKnownFolderName.Root, view);
// Find specific folder
foreach (Folder f in findFolderResults)
{
// Show FolderId of the folder "test"
if (f.DisplayName == "test")
{
Console.WriteLine(f.Id);
}
}
}
private static bool Callback(string redirectionUrl)
{
bool result = false;
var redirectionUri = new Uri(redirectionUrl);
if (redirectionUri.Scheme == "https")
{
result = true;
}
return result;
}

You could find the unique id of the folder using the below code:
ExchangeService Service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
Service.UseDefaultCredentials = false;
Service.Credentials = new WebCredentials("yourUserID", "yourPassword");
Mailbox ProdSupportMailbox = new Mailbox("ProdSupport#company.com");
Service.AutodiscoverUrl("ProdSupport#company.com");
FolderView view = new FolderView(100);
view.PropertySet = new PropertySet(BasePropertySet.IdOnly);
view.PropertySet.Add(FolderSchema.DisplayName);
view.Traversal = FolderTraversal.Deep;
FindFoldersResults findFolderResults = server.FindFolders(WellKnownFolderName.Root, view);
// find specific folder
foreach(Folder f in findFolderResults)
{
// show folderId of the folder "Test"
if (f.DisplayName == "Test")
{
Console.WriteLine(f.Id);
}
}

Sending email from the specified Outlook Account

I am using Outlook2013 which has a number of mailboxes from both exchange and pop servers.(Rob#mydomain.com[default exchange], rob#somethingdifferent.com[POP], support#mydomain.com[exchange])
I am trying to use Outlook automation to send an email using the support#mydomain.com account.
The problem I am having is the below code creates a mail item in the support outbox but the from field is rob#mydomain.com not support#mydomain.com. This stops it from being sent.
I would like to change the from address to support#mydomain.com. I thought that by setting the Sendusingaccount property did this.
Any help is greatly appreciated.

Yes, you can use the SendUsingAccount property to set up the correct account you need to send items from.
public static Outlook.Account GetAccountForEmailAddress(Outlook.Application application, string smtpAddress)
{
// Loop over the Accounts collection of the current Outlook session.
Outlook.Accounts accounts = application.Session.Accounts;
foreach (Outlook.Account account in accounts)
{
// When the e-mail address matches, return the account.
if (account.SmtpAddress == smtpAddress)
{
return account;
}
}
throw new System.Exception(string.Format("No Account with SmtpAddress: {0} exists!", smtpAddress));
}

Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
// 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.

// Set the subject.
oMsg.Subject = _subject;

oMsg.HTMLBody = _message;
oMsg.To = _recipient;

oMsg.BCC = _bcc;
#region Send via another account
// Retrieve the account that has the specific SMTP address.
Outlook.Account account = GetAccountForEmailAddress(oApp , "support#mydomain.com");
// Use this account to send the e-mail.

EWS - Get a custom header

Hello I am using the following code to get the custom header from EWS.
But unfortunately it's not returning the header. I looked into the outlook for the headers using Mapi tool, where I can see the headers.
Any suggestions please.
service = ExchangeServiceHelpers.GetBinding();
// Bind the Inbox folder to the service object
var inbox = Folder.Bind(service, WellKnownFolderName.Inbox);
var searchFilter = ExchangeServiceHelpers.PopulateSearchFilters();
var view = new ItemView(int.MaxValue); // Search operation should return maximum number of elements.
// Defines a property set that contains the schematized Internet message headers.
var headerProperty = new ExtendedPropertyDefinition(
DefaultExtendedPropertySet.InternetHeaders,
"x-worksitefolderemailid",
MapiPropertyType.String);
var columns = new PropertySet(BasePropertySet.IdOnly, EmailMessageSchema.InternetMessageId, headerProperty);
view.PropertySet = columns;
// Fire the query for the unread items
var findResults = inbox.FindItems(searchFilter, view);
// Loop through the search results.
foreach (EmailMessage message in findResults)
{
try
{
message.Load(
new PropertySet(new PropertyDefinitionBase[] { ItemSchema.MimeContent, ItemSchema.Subject}));
string mailAddress = GetFolderId(message, headerProperty); // Get internet header
if (string.IsNullOrEmpty(mailAddress))
{
Logger.Info(
string.Format("Email '{0}' doesn't have folder id address. Marking as Read Item.",
message.Subject));
ExchangeServiceHelpers.MarkMessageAsRead(service, message.Id); // Marking the email item as Read prevents the item to be returned in further search results.
continue;
}
}
catch (Exception e)
{
Logger.Error(e);
}
}
private static string GetFolderId(EmailMessage message, ExtendedPropertyDefinition headerProperty)
{
try
{
if (message.ExtendedProperties == null || message.ExtendedProperties.Count == 0)
{
Logger.Info(
string.Format("Email '{0}' doesn't have any extended properties. Marking as Read Item.",
message.Subject));
return string.Empty;
}
//message.InternetMessageHeaders
foreach (ExtendedProperty property in message.ExtendedProperties)
{
if (property.PropertyDefinition == headerProperty)
{
return property.Value.ToString();
}
}
}
catch (Exception ex)
{
Logger.Error(ex);
}
return string.Empty;
}

Naresh,
The inbox.FindItems() call won't return the internet headers. You'll need to update message.Load() to use a property set that includes headerProperty.
With regards,

Execute mail reader program without visual studio

With reference to my previous question, I already wrote my program and it is working awesome when I am using VS2008 for run it.
I have two more questions:
1. I want to check with you guys when I run my program all the mail are appearing in VS output as xml file, but I never used to print them in output. is it usual for all or I need to add something to remove it. I feel it takes long time from my PC to show mails in output.
2. my second question is that when I want to use only exe file stand alone(run program via exe file not with VS ) I am receiving below error and program is hanging & close.
"MailReader has encountered a problem and needs to close. We are
sorry for the inconvenience."
As I mentioned above this program is working fine in VS.
I copy part of my code that read mails and split them for your reference.

For issue #1 - you are viewing the XML output likely because you have EWS tracing enabled. You need to set ExchangeService.TraceEnabled to false or comment it out entirely. (You also have many duplicate lines of code you need to cleanup.)
service.TraceEnabled = false;
For issue #2 - you need to determine the actual .NET exception. Without this - we cannot help you further. It could be crashing for countless reasons. Please provide a stack trace.
