explanation for non-techies**

Imagine you are sending out invitations to a big party, and you want to make sure everyone knows the dress code. Instead of telling each person individually, you send a message to a group chat that includes all your friends. However, some friends might not see the message right away, or they might not understand how important the dress code is.

In the world of email and data protection, Microsoft has introduced a feature in their Purview compliance portal that works a bit like ensuring everyone in your group chat gets the dress code message clearly. When you send an email to a distribution group, which is like a group chat for emails, this feature makes sure that every single person in that group is checked against certain rules. These rules are there to prevent sensitive information from being shared accidentally, much like making sure everyone knows to wear the right outfit to your party.

The feature is called Data Loss Prevention (DLP), and it works by expanding the distribution group. This means it looks at each individual recipient within the group to see if any rules apply to them. If someone is about to send an email with sensitive content, a policy tip will pop up, like a gentle reminder, letting them know they might be about to share something they shouldn't. It's like a friend tapping you on the shoulder to remind you about the dress code before you leave the house.

This way, organizations can be more confident that everyone is aware of the rules, and it helps prevent accidental sharing of sensitive information. Just like ensuring everyone at your party is dressed appropriately, this feature helps keep emails safe and compliant with company policies.
