MailItem.ReceivedByEntryID Property (Outlook)
Published: July 16, 2012
Returns a String representing the EntryID for the true recipient as set by the transport provider delivering the mail message. Read-only.
This property corresponds to the MAPI property PidTagReceivedByEntryId.
If you are getting this property in a Microsoft Visual Basic or Microsoft Visual Basic for Applications (VBA) solution, owing to some type issues, instead of directly referencing ReceivedByEntryID, you should get the property through the PropertyAccessor object returned by the MailItem.PropertyAccessor property, specifying the PidTagReceivedByEntryId property and its MAPI proptag namespace. The following code sample in VBA shows the workaround.
Public Sub GetReceiverEntryID() Dim objInbox As Outlook.Folder Dim objMail As Outlook.MailItem Dim oPA As Outlook.PropertyAccessor Dim strEntryID As String Const PidTagReceivedByEntryId As String = "http://schemas.microsoft.com/mapi/proptag/0x003F0102" Set objInbox = Application.Session.GetDefaultFolder(olFolderInbox) Set objMail = objInbox.Items(1) Set oPA = objMail.PropertyAccessor strEntryID = oPA.BinaryToString(oPA.GetProperty(PidTagReceivedByEntryId)) Debug.Print strEntryID Set objInbox = Nothing Set objMail = Nothing End Sub
