explanation for non-techies**

Imagine you're organizing a big event and you've sent out invitations to various groups of people, like family, friends, and colleagues. Each group might have different preferences or restrictions about what they can bring or do at the event. To make sure everyone gets the right information, you need to expand each group and address the needs of each individual.

In the world of email and data protection, a similar concept is applied through a feature in Microsoft Purview's compliance portal called Data Loss Prevention (DLP). When you send an email to a distribution group, it's like sending an invitation to a group of people. However, each person in that group might have different rules about what kind of information they can receive.

The feature of enabling policy tips for recipients when emailed as part of a distribution group is like having a system that automatically checks each person's preferences and restrictions before they receive the invitation. This process is known as Distribution Group (DG) expansion. It ensures that every recipient in the group is evaluated according to the DLP rules set by the organization.

This is important because it helps prevent sensitive information from being shared with people who shouldn't have access to it. Just like you wouldn't want to send a vegetarian menu to someone who eats meat, you don't want to send sensitive data to someone who isn't authorized to see it. By expanding the distribution group and applying the DLP rules, organizations can increase the confidence that users will receive relevant warnings while drafting emails with sensitive content. This helps protect the organization's data and ensures compliance with data protection policies.
