Consider the following scenarios in a Microsoft Exchange Server 2013 or Microsoft Exchange Server 2010 environment:
You create an email message and save the email message as an Outlook Template (.oft) file in Microsoft Outlook.
You open the .oft file, you generate an email message, and then you send the email message.
You open the .oft file, you generate another email message, and then you send the email message.
You send an email message in Outlook.
You open the email message in the Sent Items folder, and then you resend the email message.
You create an email message and save the email message in the Drafts folder.
You copy and paste the email message into a folder in Outlook.
You send both email messages.
In these scenarios, the two email messages in the Sent Items folder of the mailbox have the same PR_INTERNET_MESSAGE_ID property in the Microsoft Exchange Server MPAI Editor (MFCMAPI). Additionally, the second email message that you send is not delivered to recipients, and you do not receive a non-delivery report (NDR).
This issue occurs because the Exchange store handles the PR_INTERNET_MESSAGE_ID property incorrectly for the two email messages.
