For inter-office emails, it probably is not necessary, but it would be harmless if included. You could probably create some sort of template to be used in your email clients with the disclaimer already included, rather than part of the senders "signature". + 0 Votes Reponse To Answer wizard57m-cnet Moderator 1 year ago For simplicity, just use the same disclaimer. That way, if (WHEN) someone sends something outside the company, your disclaimer will still be intact.
