Read Receipt MS Outlook

Question

I am trying to receive confirmations if a user read or deleted an email.  Also, I would like to capture if the email was delivered.  I have the delivery receipt working, but the read receipt is not working.  The email accounts are used on a MS Exchange Server 2010.  I am submitting my code.  Thanking you in advanced for any help.

   PrivateSub Button1_Click(ByVal senderAs System.Object,ByVal e As System.EventArgs)Handles Button1.Click

       Try

           Dim displaymessageAs Boolean

           Dim objOutlookAs Outlook.Application

           Dim objOutlookMsgAs Outlook.MailItem

           Dim objOutlookRecipAs Outlook.Recipient

           ' Create the Outlook session.

           objOutlook = CreateObject("Outlook.Application")

           ' Create the message.

           objOutlookMsg = objOutlook.CreateItem(Outlook.OlItemType.olMailItem)

         With objOutlookMsg

               ' Add the To recipient(s) to the message.

               objOutlookRecip = .Recipients.Add("[e-mail]")

               .ReadReceiptRequested = True

               'set delivery receipt

               .OriginatorDeliveryReportRequested = True

               ' Set the Subject, Body, and Importance of the message.

               .Subject = "This is a test"

               .Body = "This is a test." & vbCrLf & vbCrLf

               objOutlookRecip.Resolve()

              .Save()

               .Send()

           End With

           objOutlook = Nothing

       Catch exAs Exception

           MsgBox(ex.ToString)

       End Try

   End Sub

EndClass

Answer 1

Is recipient's mailbox actually configured to send read receipts?

Can you check in "Options | Mail | Tracking | For any message received that includes a read receipt request"?

Hi,

as I remember, read receipts could be filtered out by:
A: Firewall
B: Exchangeserver

Are the Emails transmittet inside the Organization, or via Internet (SMTP)
When SMTP, can you check the Email-Header on a Recipient side if the Info is in there?

From: "Test User" [e-mail]
To: "Other User" <[e-mail]>
Read-Receipt-To: "Test User" <[e-mail]>
Disposition-Notification-To: "Test User" <[e-mail]>
Subject: Read Receipt Header Test

Answer 4

It was the firewall.  It is working now.  However, to answer you questions, it is inside the organization.  Yes, the email - header is in there.  My other question is how do you determine if the email was deleted?

Hi Quanny,

when it's only for Emails inside the Organization, then you could create an Eventsink on the Exchangeserver as far as I know. 
For external Emails I think there is no such Option.

If all Users have an AddIn, I think it's possible to catch the Item-Delete using Dmitris Redemption Library?
Not sure - Dmitri - is it possible?

Hope this helps,

Answer 6

It all depends on where and how the message is deleted. What is the exact scenario?
