MS-900 Practice Question: Describe Microsoft 365 pricing, licensing, and support
Which TWO support plans provide access to Microsoft 365 technical support via phone and email with a guaranteed response time?
⚠ Common exam trap
Candidates often confuse Microsoft Premier Support (a legacy plan) with Unified Support, or assume that Developer Support includes phone support for administrative issues, but the exam specifically tests that only Unified Support and Microsoft 365 Business Support offer phone and email with guaranteed response times.

Correct answer & explanation
✓
Microsoft Unified Support
Microsoft Unified Support (B) and Microsoft 365 Business Support (C) are the only plans that include phone and email technical support with guaranteed response times based on severity. Microsoft 365 Business Support is designed for organizations with fewer than 300 users, while Unified Support is an enterprise-grade plan that offers proactive services and faster SLAs. Both plans explicitly list phone and email as supported channels with defined response time commitments in their service descriptions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Developer Support
Why it's wrong here
Microsoft Developer Support is a specialized channel intended for developers troubleshooting code, SDKs, and usage of development tools like Visual Studio and Azure DevOps. It does not provide the level of phone or email support needed for Microsoft 365 tenant administration, licensing, or messaging issues. Because it is scoped to development scenarios, it cannot fulfill a general Microsoft 365 technical support need, making it an incorrect choice here.
- ✓
Microsoft Unified Support
Why this is correct
Microsoft Unified Support is the current enterprise-level support offering that consolidates all break-fix and proactive services into a single agreement. It provides 24/7 phone and email access to Microsoft engineers, defined response time SLAs, and account-level support management. This plan explicitly covers Microsoft 365 technical incidents, making it a valid answer for accessing M365 tech support.
- ✓
Microsoft 365 Business Support
Why this is correct
Microsoft 365 Business Support is the support plan bundled with Microsoft 365 Business subscriptions, designed for small and medium organizations. It gives administrators access to phone and email support with published response times, and it covers technical issues with core M365 services such as Exchange, SharePoint, and Teams. This plan is directly marketed as a way to get Microsoft 365 technical help, so it is correct.
- ✗
Microsoft Premier Support
Why it's wrong here
Microsoft Premier Support was a legacy enterprise support plan that historically provided phone/email support and account management. Microsoft has discontinued Premier Support and replaced it with Microsoft Unified Support, meaning Premier is no longer available to new or renewing customers. Since it is a retired offering rather than an active channel for Microsoft 365 technical support, it is incorrect for this question.
- ✗
Microsoft Community Support
Why it's wrong here
Microsoft Community Support refers to free online forums and user-to-user discussion groups hosted by Microsoft. These communities rely on volunteers and other users, so there is no guaranteed response time, no SLA, and no direct access to Microsoft engineers. It is not an official paid support plan and cannot deliver the structured technical support promised by the other plans, making it the wrong choice.
