"The properties of the message have been changed" prompt when forwarding/replying in Outlook

When users open a message in its own window that has a pdf attachment and replies or forwards the message; when they close the original window, outlook prompts "The properties of the message <email_subject> have been changed. Want to save your changes to this message?"

Steps to recreate this issue:

  • Message must have pdf or txt attachment
  • Open the original message in its own window
  • Reply-to or forward the message
  • Closing original message that was previously opened in its own window

Attempts to disable add-ins or running outlook in safe-mode do not resolve this issue.

    To assist you in this case, would like to confirm when this issue start to occurs?

    Besides this, do you have installed any antivirus software on your system? If so, request you to please kindly try to disabling the integration of the antivirus software in Outlook (or simply disable Antivirus software) and then check if it makes any difference.

    • Try going into Outlook > File tab > Options and select Mail.
    • In the Replies and forwards area, verify that when replying and forwarding a message is selected with Include original message text.
    • In the Save message area, verify that use “Unicode format” is checked. Also make sure that "when replying to a message that is not in the inbox, save the reply in the same folder" is unchecked.
    • Screenshot for your reference:
