"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.
