Consider the following scenarios in a Microsoft Exchange Server 2013 or Microsoft Exchange Server 2010 environment:
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).
Scenario 1
- 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.
Scenario 2
- You send an email message in Outlook.
- You open the email message in the Sent Items folder, and then you resend the email message.
Scenario 3
- 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).
