We have 8.1 SP9... when we try to send any email (response o forward), the email is sent to the final recipient mailbox but the system say "ERROR: Invalid ID Request", and the mail is not attached to the original Request and is not present inside the histori with the total mailing tracing .

In addition, we can be approve, but the system respons the same (Invalid ID request), and when the user receive de email and try to click it, the system cannot find the approved request.

Best regards.
