Very recently some Users are receiving the message:
The properties of the message "Attached Image" have been changed
They receive this intermittently and only when forwarding an email sent to them with an attachment. Performing the same function on the same email may not always result in the message appearing. When it does appear the email forwards without issue but when closing the original email (the one forwarded) this message appears. No action was taken on the attachment - none. A simple received email is opened and then forwarded.
