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
