Exchange rule issue with "Prepend the subject of the message with"

Dear all,

I am encountering an issue that I have been unable to resolve despite researching extensively online.

Contextually, I need to forward all incoming emails from a distribution list to a shared mailbox. To identify these forwarded emails in the shared mailbox, I attempted to add a text to the subject line (namely, "The DL should no longer be used by my colleagues in a few months").

Here's what I've done so far:

  • Condition: "Recipient", "Address matches any of these patterns" (I've also tried "The sender address includes")
  • Actions:
    • "Add the recipient:" "to the Cc Box" => my shared mailbox
    • "Prepend the subject of the message with"

The forwarding is working as expected, but the subject line is not being prepended with the chosen text.

Have I missed something?

Thank you all in advance for your help.

Best regards, Guillaume

  • Guillaume365 Have you tried to swap the two actions: first prepend the text, than CC the mail?

      Deleted Thanks for you prompted reply. Yes I also tested to invert the 2 actions, and I get the same behavior.

        Guillaume365 What about the original recipient: does he get a modified subject line?

    1) Try to add X-header instead of prepending the Subject
    2) To identify these forwarded emails in the shared mailbox you can create a Power Automate flow.
