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.

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.
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.
I am reading continuous emails from the exchange server and processing their attachments. I have seen various examples of the same but I still get error
You must load or assign this property before you can read its value
My code is as below
ItemView itemView = new ItemView(NoEmailProcess);
itemView.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Ascending);
FindItemsResults<Item> searchResults = service.FindItems(folder.Id, itemView);
foreach (var item in searchResults)
{
if (item is EmailMessage)
{
item.Load();
try
{
// Process my email
}
catch
{
// error
}
}
}
The thing to note is that I dont get this error every time. I get it 10% of times and never during debugging
I was wondering should I use 'Bind' before the 'Load'?
EmailMessage.Bind
Not sure what the problem could be. Could someone please help with areas I should investigate?
An exception with the message "You must load or assign this property before you can read its value" is thrown if you attempt to read a property which isn't present on Item.
The Items returned by service.FindItems contain only some properties. Though the property ItemSchema.HasAttachments is returned for an Item, the property ItemSchema.Attachments is missing. Thus you can only check if there are attachments present on an Item. But trying to read them at once will throw the shown exception.
Before you can read the property ItemSchema.Attachments you need to load it first, You can do it by ItemSchema.Bind or ItemSchema.Load. Both calls result in a GetItem request.
Since a GetItem request returns the property ItemSchema.Attachments too (see the linked MS doc above) you are safe to read it.
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");
Is it possible to determine the Exchange Server ItemID for a MailItem (the selected Item in the active explorer)? The solution I am working on has an Outlook AddIn component and another component that accesses mail items through EWS.
I have code similar to the below in my Outlook addin:
Outlook.Explorer ActiveExplorer = Globals.ThisAddIn.Application.ActiveExplorer();
object selectedItem = ActiveExplorer.Selection[1];
Outlook.MailItem selectedEmail = selectedItem as Outlook.MailItem;
In this way I can access certain properties of the email but it is important to the workings of the overall solution that the property values are exactly the same as those returned by EWS. For example, if the property returned a time, it would be important that the time matched down to the millisecond.
If I had the ItemID I could bind to and work with the Item (from within the addin) using something like the below.
Item myItem = Item.Bind(MyExchangeService, MyItemID);
On a whim I have tried binding to MailItem.EntryID but I got a malformed ID error (which didn't surprise me). I have been trying to determine if the Exchange ID was available through MailItem.PropertyAccessor.GetProperty but I am not really familiar with accessing properties in this way and haven't had any luck so far.
Thoughts?
I came across the following Stack Overflow post which didn't exactly answer my question but changed my focus to converting the EntryID into the EWS ID rather than finding the EWS ID.
Exchange ItemID differs from GlobalAppointmentID for Outlook AddIn
With this new angle I was able to find the following site which directly addressed my issue.
https://bernhardelbl.wordpress.com/2013/04/15/converting-entryid-to-ewsid-using-exchange-web-services-ews/
I have posted the code here in full in case the link gets broken.
string ConvertHexEntryIdToEwsId(ExchangeService esb, string sID, string strSMTPAdd)
{
AlternateId objAltID = new AlternateId();
objAltID.Format = IdFormat.HexEntryId;
objAltID.Mailbox = strSMTPAdd;
objAltID.UniqueId = sID;
AlternateIdBase objAltIDBase = esb.ConvertId(objAltID, IdFormat.EwsId);
AlternateId objAltIDResp = (AlternateId)objAltIDBase;
return objAltIDResp.UniqueId;
}
