We have an Exchange 2010 & Outlook 2010 environment.
When a bulk item is sent to multiple users, each of the message has the same unique message-ID. I am researching a way to identify to validate that it's the exact same item.
My problem is, there's no header information in the sent item from the sender's mailbox. The MFCMAPI for the sent item doesn't contain the PR_Internet_Message_ID field.
Does anyone know how to identify and validate that it is the same? OR any documentation that I should see these differently?
Edit:
I used MFCMAPI to review a few more messages from my sent items. Oddly, I found the PR_Internet_Message_ID on one while another message that I've sent does not contain this field. Both were composed by me, and not a part of any email chain. This have me scratching my head even more
