Outlook.MailItem custom properties issue - c#

i have the following situation for my Add-In (Office >= 2010):
I want to add some custom properties to an Outlook.MailItem (property must be mail associated) while the mailtext is written.
If this mail is sent i want to grap the send event and get the previously set properties again, doing something and removing the properties and continue sending.
Problem if i use PropertyAccessor:
I use it as follows to save the property while writing the mail:
string propTag = "http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/test_property"
mailItem.PropertyAccessor.SetProperty(propTag, value);
And to read the property again on sending the mail:
string propTag = "http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/test_property"
string readProperty = mailItem.PropertyAccessor.GetProperty(propTag);
works if cached mode is enabled on exchange
works NOT if cached mode isn't enabled... i can't find the previously setted properties anymore (Exception with unknown property is thrown)
OutlookSpy (http://www.dimastr.com/outspy/home.htm) can find the property on sending so does anyone knows how to read the properties in a different way?
I would thank you very much for every help.

You need to call Save if you want your changes to be persisted.

C# Attach to open outlook email, edit and send

I am trying get some C# to attach to an open reply-email (triggered manually by user), on the already running instance of Outlook (opened manually by user). The code should identify the open reply email, edit the subject line and body of the email and send the email.
The problem is that I get as far as identifying the running instance of Outlook and assigning it to an object using one of the Marshal methodsoutApp = Marshal.GetActiveObject("Outlook.Application") as Application, but then I cannot cast it to a MailItem type in order to manipulate its elements e.g. the subject line, body, etc...something like MailItem mailItem = (MailItem)outApp.CreateItem((OlItemType.olMailItem)); throws an invalid cast exception at runtime.
Apologies if I am wrong, but could not find a single example close to this exact sequence of events, one of the closer ones is this post c# outlook open existing instance and reply to email
but then it goes a whole different way. There are tons of posts on how to use the Microsoft.Office.Interop.Outlook to OPEN and then use an instance of Outlook, but hardly anything (that I could find) on how to use an open instance. Any help is appreciated, thank you.
EDIT 08102019:
The code is used from an RPA platform, so there is no risk of it being picked up as malware. The "user" is just a virtual user on an account with purpose-made permissions and a controlled environment...sorry, nothing dark here :-). Anyway, here is the code I am using at the moment which creates a new instance and saves it to drafts in Outlook. It is not what I set out to do, as I explained above, this is just a temporary fix:
OutlookApp outlookApp = new OutlookApp();
MailItem mailItem = (MailItem)outlookApp.CreateItem(OlItemType.olMailItem);
mailItem.To = "test#test.com";
mailItem.Subject = "Test Email Generation";
mailItem.HTMLBody = "<html><body>This is the body of the email.</strong>.<br/> This is another line in the body of the email.</body></html>";
mailItem.Display(false);
System.Threading.Thread.Sleep(3000);
mailItem.Close(OlInspectorClose.olSave);
Marshal.ReleaseComObject(outlookApp);
To get the opened mail item in the inspector window you need:
Use the ActiveInspector method to get an instance of the Inspector class.
The Inspector.CurrentItem property returns an Object representing the current item being displayed in the inspector.
Set any properties like Subject, Body, Recipients and etc.
To get the inline response in the Explorer window you need to use the Explorer.ActiveInlineResponse property which returns an item object representing the active inline response item in the explorer reading pane.

c# VSTO Outlook email body from opened window

I've a problem with my VSTO application for Outlook. I want to process the email body from a selected e-mail.
For selected e-mails out of the "default" list this code works fine:
Object selItem = Globals.ThisAddIn.Application.ActiveExplorer().Selection[1];
Outlook.MailItem mailItem = (Outlook.MailItem)selItem;
return mailItem.Body;
But if a user opens an email from the list with a double click, the email is displayed in a new window. If the addin is executed in this window (over the ribbon), the email from the list is still used (which is now in the background).
Is there a way to find out if the plugin was started in a separate window and then get the email body from it?

Coincidentally, I just dealt with something similar to this. My situation isn't identical, but since I could easily piece together what it seems like you're looking for see below. I haven't tested this, and obviously you'll have to handle passing the correct reference to your Outlook Application, but since i had this immediately available I figured it would pass it along with the hope that you'll find it helpful.
private static void ribbonButton_Click(object sender, RibbonControlEventArgs e)
{
Outlook.Application application = new Outlook.Application();
Outlook.Inspector inspector = application.ActiveInspector();
if (application.ActiveExplorer().Selection[1] is Outlook.MailItem explorerMailItem)
{
// Write code to handle message if sourced from explorer (i.e., Reading Pane)
}
else if (inspector.CurrentItem is Outlook.MailItem inspectorMailItem)
{
// Write code to hanlde message if sourced from inspector
// (i.e., openened (double-clicked) message
}
}
When you double click on email item you open an inspector window and you can access it by using Application.ActiveInspector() method. The Inspector object has CurrentItem property which represents the opened item.
Also, you should avoid using multiple dots in expressions and properly release COM objects.

Read Undelivered email body in C# windows form

I am developing one tool to keep track of emails and would like to trace the emails undelivered to sender.
I dont want to use any third party tool or any external reference
What I have tried?
-To read report Item but Body is in Chinese like language
-Googled on some solutions but nothing is working i.e. solution is related to
//PR_TRANSPORT_MESSAGE_HEADERS
link to get property name "http://schemas.microsoft.com/mapi/proptag/0x0C1A001F"
outlook PropertyAccessor class
PropName link is not working anymore.
Could anyone here please help me I would like to get from which sender the email delivery is failed.
Thank you in advance.
The PR_TRANSPORT_MESSAGE_HEADERS property contains the same Diagnostic information shown in the body. You just need to read it using the PropertyAccessor class and parse the string with From and To entries.
Outlook.PropertyAccessor oPA = reportItem.PropertyAccessor;
string transportHeaders = (string)oPA.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x007D001E");

How to get the SMTP Adress of the sender outlook / Exchange

I am trying to get the SMTP Adress of the sender in an outlook plugin.
This worked as expected when I follow the examples from MSDN
like this one here:
private void GetSMTPAddressForRecipients(Outlook.MailItem mail)
{
const string PR_SMTP_ADDRESS =
"http://schemas.microsoft.com/mapi/proptag/0x39FE001E";
Outlook.Recipients recips = mail.Recipients;
foreach (Outlook.Recipient recip in recips)
{
Outlook.PropertyAccessor pa = recip.PropertyAccessor;
string smtpAddress =
pa.GetProperty(PR_SMTP_ADDRESS).ToString();
Debug.WriteLine(recip.Name + " SMTP=" + smtpAddress);
}
}
But since some time (some weeks) the reference schema at
http://schemas.microsoft.com/mapi/proptag/0x39FE001E
can not be resolved anymore.
Errormessage:
System.Runtime.InteropServices.COMException: http://schemas.microsoft.com/mapi/proptag/0x39FE001E Property unknown or ca not be found.
If I try the URL in a browser I get:
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
All examples I can find (for office 2013 and above) are pointing to ressources at http://schemas.microsoft.com/mapi/proptag/SOMETHING
I also could not find any info in forums or oon MSDN that this moved or changed ..
Is anyone else running into this ?
Is ther a known solution or workaroud.
http://schemas.microsoft.com/mapi/proptag/0x39FE001E is not a link, it the actual DASL property name that the PropertyAccessor object expects. The format is different for the fixed and named MAPI properties (e.g. http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/85100003).
You can look at the MAPI properties and their DASL names in OutlookSpy (I am its author - click IMessage button).
Also keep in mind that you should not expect any particular MAPI property to be present - they are not guaranteed to be present and you must expect and handle errors returned by the PropertyAccessor object.
In your particular case, you can are not checking the SMTP address of a sender, you are working wit the message recipients. For the recipients, check if the PR_SMTP_ADDRESS property is there. If not, open the adders entry (Recipient.AddressEntry) and check for that property from the AddressEntry. You can also check for the presence of the PR_EMS_AB_PROXY_ADDRESSES multivalued property (an array is returned). You can so try AddressEntry.GetExchangeUser().PrimarySmtpAddress (be prepared to handle errors and nulls).
Once again, take a look at the message with OutlookSpy to see which property is present.

Determine if MailItem is open in Compose or Read mode

Is there some way that I can determine if a MailItem is being opened in a ReadMail view (not sure about the terminology here) or in a Compose view. That is, am I opening a mail that has been sent to me, or am I opening a mail to send to someone.
I've checked the MailItem and the Inspector objects but can't find anything of relevance. Unfortunately I don't know how to access specific Properties (I've seen some GetProperty() method somewhere) so I don't know if I could access it via that..
I was hoping that there would be something I could do like:
// where OutlookApp is my Outlok Application
Outlook.Inspector inspector = OutlookApp.ActiveInspector();
Outlook.MailItem item = inspector.CurrentItem as Outlook.MailItem;
if (item.IsOpenInComposeView)
{
// ...
}
_MailItem.Sent will be true when the message is in Read mode, and false when the message is in Compose mode.
