MS-900 Describe Microsoft 365 apps and services Practice Question
Which THREE Microsoft 365 services are included in Microsoft 365 E3 that are NOT in Microsoft 365 Business Basic?
⚠ Common exam trap
Watch out — candidates often assume all 'Business' plans lack advanced security features, but the question specifically asks for services included in E3 that are NOT in Business Basic, and Exchange Online and Teams are common to both, while desktop Office apps and Intune are also exclusive to E3.

Correct answer & explanation
✓
Microsoft Purview Information Protection
Microsoft Purview Information Protection (formerly Azure Information Protection) is included in Microsoft 365 E3 but not in Microsoft 365 Business Basic. Business Basic only includes Exchange Online, Teams, and web/mobile versions of Office apps, with no data classification or rights management capabilities. E3 adds full Purview features like sensitivity labels and encryption for compliance and data loss prevention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Exchange Online
Why it's wrong here
Exchange Online is a foundational messaging service that is present in every Microsoft 365 plan, including Business Basic and E3. Because it provides the same mailbox, calendar, and basic compliance capabilities in both offerings, it cannot be considered an E3-only service. The question asks for services that differentiate E3 from a lower-tier plan, so Exchange Online is incorrect.
- ✓
Microsoft Purview Information Protection
Why this is correct
Microsoft Purview Information Protection (formerly Azure Information Protection) delivers persistent data classification and protection through sensitivity labels and encryption. These capabilities are embedded in the E3 security and compliance suite, whereas Business Basic only includes minimal eDiscovery and retention features without full information protection. Since this is a premium compliance feature absent from Business Basic, it is a valid selection.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams is the core collaboration hub for chat, meetings, and shared files, and it is included in all Microsoft 365 plans, including the entry-level Business Basic. The functionality available in Business Basic is sufficient for most team collaboration scenarios, so Teams does not represent an upgrade benefit exclusive to E3. Therefore, selecting Teams as a distinguishing E3 service is incorrect.
- ✓
Desktop versions of Office apps
Why this is correct
Business Basic deliberately limits Office to browser-based and mobile versions of Word, Excel, and PowerPoint to keep the subscription lower cost. E3, on the other hand, grants installed desktop applications for both PC and Mac, which work offline and with advanced features. This Office client access is a key differentiator between the two plans, making it a correct answer.
- ✓
Microsoft Intune
Why this is correct
Microsoft Intune provides cloud-based unified endpoint management, including mobile device management (MDM) and mobile application management (MAM) policies for Windows, iOS, and Android. Intune is part of the Enterprise Mobility + Security (EMS) suite bundled with E3, but Business Basic does not include any EMS components. Its presence in E3 and absence in Business Basic make it a third correct choice.
