Microsoft plans to surface recommendations to use communications compliance policies as part of its DLP workflow. That sounds acceptable, but it’s the second example of how Microsoft pushes high-priced premium features to Office 365 tenants through DLP. Apart from the undesirability of pushing features to customers through software, communications compliance is not something that you implement on a whim, so why does Microsoft think this is a good idea?
Microsoft 365 organizations which use Teams but don’t have a Teams DLP policy will see a Compliance Center widget recommending the creation of a DLP policy. Sounds good, and the policy covers the most common sensitive data types that people worry about. The downside is that Teams demands Office 365 E5 licenses for DLP policies. You might not know that, but you will if you accept the recommendation.
