Implement sensitivity labels, encryption, auto-labeling, and protection policies that work consistently across Microsoft 365, Copilot, Teams, SharePoint, and Exchange.
The biggest mistake in Information Protection is a taxonomy of twenty labels nobody remembers. Limit yourself to a handful of levels everyone can explain, such as Public, Internal, Confidential, and Highly Confidential. A label set that fits on a sticky note gets used; a label set that needs a training gets ignored.
Do not count on users to label every document by hand. Use auto-labeling based on content (credit card numbers, customer data, contract terms) so sensitive information gets the right protection even without human action. Test the policy in simulation mode first, because an overly aggressive rule labels half the organization Confidential and breaks workflows.
A label with no attached protection is little more than a sticker. Decide per level which encryption and usage rights apply: who may open, copy, print, or forward. That way the protection travels with the file, even outside the organization.
Labels must mean the same thing in Microsoft 365, Teams, SharePoint, and Exchange. A Confidential document that suddenly becomes freely shareable through Teams undermines the whole model. Configure the policy centrally and check that every workload respects it.
Microsoft 365 Copilot honors sensitivity labels and usage rights, but only when they are applied correctly. Explicitly test that Copilot does not summarize Highly Confidential content for users without rights. Information Protection and Copilot governance are two sides of the same coin.
