TL;DR
AB-250 is Microsoft's Associate-level exam for the Dynamics 365 Contact Center AI Engineer Associate credential. It tests deploying and configuring Dynamics 365 Contact Center across six weighted domains — channels is the heaviest at 30-35% — passing at 700/1000. It is not the same exam as MB-230, and it now fills the Business Applications partner-skilling slot vacated by the retired MB-240.
Is AB-250 the Same as MB-230, or a Replacement for MB-240?
Neither, exactly — and the distinction matters for how you study. AB-250 shares real territory with MB-230 (Microsoft Dynamics 365 Customer Service Functional Consultant), since both credentials touch Dynamics 365 Contact Center. MB-230's own audience profile lists Contact Center as one of several components a Customer Service consultant coordinates on, alongside case management, knowledge, and Customer Voice. But MB-230's current skills-measured document (updated March 11, 2026) weights Manage cases in Customer Service at 51-55% of the exam — case management, SLAs, and knowledge management dominate. AB-250 never tests case management at all. Its heaviest domain, Implement channels, sits at 30-35% and goes deep into chat, digital, and voice channel configuration that MB-230 does not test to the same depth.
The MB-240 relationship is different in kind. MB-240 (Microsoft Dynamics 365 Field Service Functional Consultant Associate) tested field service scheduling, work orders, inventory integration, and IoT-connected service — content AB-250 does not touch at all. MB-240 appears on Microsoft's list of recently retired exams with a June 30, 2026 retirement date, and Microsoft's July 2026 Partner Center announcement names the Dynamics 365 Contact Center AI Engineer Associate credential (earned via AB-250) as its replacement inside the Business Applications Solutions Partner specialization track, effective end of July 2026. That is a partner-program substitution, not a content successor — if you held MB-240, none of that field-service knowledge transfers to AB-250.

What AB-250 Actually Tests
Passing AB-250 earns the Microsoft Certified: Dynamics 365 Contact Center AI Engineer Associatecredential. Microsoft's official audience profile describes the role as a contact center engineer or solutions professional who designs, implements, and supports AI-powered contact center solutions using Dynamics 365 Contact Center and service-oriented autonomous agents — translating business and service requirements into scalable, well-governed solutions that combine human representatives with AI-driven capabilities.
In practice, that means configuring workstreams and engagement channels, designing routing strategies, configuring representative profiles, enabling Copilot-assisted productivity tools, implementing self-service agents, and monitoring operational health — typically in collaboration with customer service leaders, IT teams, and compliance stakeholders.

AB-250 Exam Domains, Weighed Against MB-230
The domain names below come directly from Microsoft's skills-measured document. Where a domain has meaningful overlap with MB-230's territory, that is called out — most domains do not overlap at all.
Domain 1: Deploy Dynamics 365 Contact Center
15-20%- • Configure the Copilot Service workspace, connectors, embedded Contact Center mode, and Copilot for third-party CCaaS solutions
- • Enable agent simulation to evaluate journeys and the Health Agent to proactively investigate configuration issues
- • Roll out agents through the Agent hub, build application-lifecycle-managed (ALM) solutions, and manage an omnichannel environment end to end
- • Configure user settings and accounts, manage security roles including custom roles and personas, and manage capacity profiles
Domain 2: Implement channels
30-35%- • Configure chat, digital, and record-based channels; build a chat widget with pre-chat surveys and proactive chat; extend the experience with the live chat SDK and the native-mobile Messaging SDK
- • Provision and manage the voice channel: integrate a non-Microsoft IVR, manage phone numbers and inbound/outbound calling profiles, and configure call recording, transcription, and real-time translation
- • Configure channel features — context variables, automatic customer identification, sensitive data masking, and auto-closing conversations
- • Configure proactive outbound campaigns (workstreams, triggers, dialing methods) and workforce management (shift scheduling, forecasting, third-party WFM integration)
Domain 3: Configure agents and AI capabilities
10-15%- • Configure Copilot summaries, the Ask a Question feature, and knowledge sources for Copilot; extend Copilot with prompt plugins and tools; interpret the Copilot analytics report
- • Configure voice agents: IVR using generative AI or classic orchestration, the Real-time Speech agent, DTMF/NLU/speech-based IVR, and multilingual voice agents
- • Secure the voice channel and configure compliant call recording and SIP header transfers inside Copilot Studio
Domain 4: Configure work distribution
10-15%- • Create and manage queues; configure prioritization, overflow and fallback, work assignment methods, and operating hours
- • Configure basic and unified routing: workstreams, work classification rules, skills-based and AI-enabled skills-based routing, intent-based routing, and preferred representative routing
- • Diagnose unified routing behavior using conversation diagnostics
Domain 5: Configure the Dynamics 365 Contact Center representative experience
15-20%- • Create experience profiles and application tab templates; configure the agent inbox with custom views, session templates, and notification templates
- • Enable productivity tools: custom productivity panels, scripts and slugs, macros, and Teams collaboration
- • Configure knowledge management: internal and external knowledge search, tables for knowledge management, and the Customer Knowledge Management agent
Domain 6: Manage analytics for the Dynamics 365 Contact Center
10-15%- • Configure the supervisor experience: supervisor settings, the Quality Evaluation agent, and supervisor actions for conversations
- • Customize KPIs and reports using the embedded Power BI editor and extend them with Power BI Desktop
- • Configure conversation diagnostics and embed telemetry from Application Insights
Domain 2 (Implement channels) is the only domain where an MB-230 background gives partial credit — MB-230 candidates already know digital and record-based channels from Extend Customer Service, but AB-250 goes considerably deeper into voice channel provisioning, IVR integration, and proactive outbound campaigns that MB-230 never tests. Domains 3, 4, 5, and 6 have essentially no MB-230 overlap.
Study Plan: What to Prioritize Depending on Your Starting Point
A 24-hour baseline weighted to each domain's exam share — adjust the total to your pace, but keep the proportions:
| Domain | Suggested hours | Exam weight |
|---|---|---|
| Domain 1: Deploy Dynamics 365 Contact Center | 3 hrs | 15-20% |
| Domain 2: Implement channels | 8 hrs | 30-35% |
| Domain 3: Configure agents and AI capabilities | 3 hrs | 10-15% |
| Domain 4: Configure work distribution | 3 hrs | 10-15% |
| Domain 5: Configure the representative experience | 4 hrs | 15-20% |
| Domain 6: Manage analytics | 3 hrs | 10-15% |
If you hold MB-230 today:cut Domain 1 (deployment fundamentals) hours roughly in half — Copilot Service workspace and user/security-role concepts will feel familiar — and redirect that time into Domain 2's voice channel and proactive outbound content, which MB-230 does not cover.
If you held MB-240 (retired):treat this as a ground-up study plan. Field service scheduling knowledge does not transfer to any AB-250 domain — budget the full 24 hours or more, with extra time on Domain 3's voice-agent content, since it is the newest material for anyone coming from a non-Contact-Center background.
Common Pitfalls
Assuming MB-230 experience covers the exam
MB-230 candidates often underestimate Domain 2. Digital and record-based channel familiarity does not extend to voice channel provisioning, IVR integration, or proactive outbound campaign configuration — all tested in depth.
Treating the Health Agent and Quality Evaluation agent as interchangeable
The Health Agent proactively investigates deployment and configuration issues in Domain 1. The Quality Evaluation agent, tested in Domain 6, evaluates conversation quality for supervisors. Scenario questions test which one applies to a given symptom.
Skipping workforce management because it feels like an HR topic
Shift scheduling, demand forecasting, and third-party WFM integration sit inside Domain 2 at real exam weight — treating them as out of scope costs points on a domain that is already 30-35% of the exam.
Assuming beta-exam pricing and duration figures are locked in
Because Microsoft has not published a final price, duration, or question count on AB-250's own exam page as of this check, any figure you see today — including on this site — should be confirmed on the official page before you schedule.
Frequently Asked Questions
Is AB-250 the same exam as MB-230?
No. MB-230 weights case management at 51-55% and treats Contact Center as one of several components. AB-250 is scoped entirely to deploying and configuring Dynamics 365 Contact Center — channels, voice, routing, agents, and analytics.
Does AB-250 replace MB-240?
For Microsoft partner-skilling purposes, yes — the Dynamics 365 Contact Center AI Engineer Associate credential (earned via AB-250) replaces the retired MB-240 (Field Service Functional Consultant Associate) in the Business Applications specialization track as of end of July 2026. The exam content itself does not overlap.
What is the passing score for AB-250?
Microsoft's official AB-250 study guide states 700 out of 1000, checked 2026-09-07.
How much does the AB-250 exam cost and how long does it take?
Microsoft's own AB-250 exam page doesn't publish a price, duration, or question count as of this check. MSCertQuiz's certification page lists $165 USD and 120 minutes, consistent with Associate-exam policy — confirm on Microsoft's page before booking.
What are the prerequisites for AB-250?
None are enforced. Microsoft recommends CCaaS implementation experience and familiarity with Power Platform, Copilot Studio, Power BI, Teams, and Microsoft Foundry.
