Scenario
You are using Exclaimer, and you notice that when a signed or encrypted message is processed, no signature is appended.
Reason
As the body of the email is contained within an encrypted file, it is not possible for Exclaimer to add a signature after it has been sent.
Resolution
The recommended method for adding signatures to encrypted emails is to apply the signature using the Exclaimer Outlook Add-in and See before you send signature rules prior to sending the email.
If you are unable to use the See before you send signature rules, then please ensure that the email is routed to Exclaimer before applying encryption to the email. For more information, please see How to apply a signature to emails before encrypting them.
