About
The MS-721 certifies IT professionals as Microsoft 365 Collaboration Communications Systems Engineers — specialists in planning, deploying, configuring, managing, and troubleshooting Teams Phone, Teams meetings, Teams Rooms, and modern UC infrastructure within the Microsoft 365 ecosystem. Launched in 2023, MS-721 replaced the retired Skype for Business infrastructure exams and reflects Microsoft's shift toward cloud-first unified communications. Candidates should have hands-on experience with Teams Phone administration, Direct Routing, Operator Connect, or similar cloud-calling deployments. The exam was substantially updated in February 2026 to reflect new Teams Premium features, Teams Rooms Pro Management, and advanced telephony scenarios.

Modern workplace communications platform enabling voice, video, messaging, and meetings across enterprise organizations.
