Curated capability groupings first, then every remaining service plan Microsoft provisions with this SKU — together they're the complete list, nothing is hidden.

| Defender for Cloud Apps Office 365 Cloud App Security (Microsoft 365 apps only) A lighter-weight cloud app discovery and control capability bundled into Office 365 E5 — a subset of the standalone Microsoft Defender for Cloud Apps. A cloud access security broker (CASB): discovers shadow IT, and applies session/access policies across sanctioned SaaS apps. The Office 365-scoped tier only covers Microsoft 365 activity; the full product extends that policy control to third-party cloud apps. |
| Other service plans |
| Exchange Foundation The baseline Exchange Online mailbox service included in most Microsoft 365 plans — hosted email, calendar, and contacts. |
