One of my new responsibilities at work is the email system (Microsoft Exchange). I noticed emails received from some of the companies have a legal notice or what you call a disclaimer at the footer of the email in other words annotations.

I searched and found out that it can be done through scripting, updating registry keys, third-party applications, etc. If you don’t mind the hassle you can ask each and every user to configure the disclaimer statement with their email signature. It will work if you are a small group but for a large number of people, it isn’t worth it.

This link is from Microsoft support.

It turns out it is easier to configure it on whatever email filter box you have, the feature is already installed you only need to configure it and set a rule to include all outgoing emails, the only downside it will only be implemented on the emails going through the email filter.
