For IT leaders

What IT leaders need to know before assigning this course

Organizations that rely on Microsoft Teams for voice, meetings, and room-based collaboration need consistent configuration standards—not ad hoc settings that create call-quality issues, emergency-calling risk, or support escalations. This intermediate MS-721 course is a fit for IT Directors assigning training to collaboration engineers, Teams administrators, or senior Microsoft 365 IT Practitioners who support Teams Phone, PSTN connectivity, meeting policies, Teams Rooms, and certified devices.

The time investment is substantial: the listed curriculum alone exceeds 36 hours, with additional skills included. Training Managers should plan this as a multi-week enablement path, especially for teams balancing production support with project work. Change-management value comes from giving the team a shared operating model for policies, dial plans, call queues, emergency calling, Direct Routing, QoS, and device updates.

CBT Nuggets Playlists can organize role-based rollout plans, while Team Reporting helps IT leaders track completion across the team.

Frequently Asked Questions

Is learning Microsoft Teams administration worth it?

Absolutely. Microsoft Teams is the de facto backbone of enterprise communication, and AI-driven features are evolving to make chat, meetings, calling, and collaboration easier and more responsive. This Microsoft Teams training goes far beyond the basics of Teams: you’ll get hands-on practice with designing and managing full-scale communication systems, giving you skills directly applicable to real hybrid workplaces and Teams premium features.

How much does the MS-721 exam cost?

The MS-721 exam costs $165 and you’ll have 100 minutes to complete it. You only get one shot at the MS-721 exam, which is why you’ll want to choose high-quality study materials that include hands-on demos and guided practice. With this MS-721 course, you can practice administering Teams and implementing Teams premium features, and be ready to pass on your first attempt.

Does knowing how to configure Teams premium features pay well?

Yes. Teams and Microsoft 365 are used (by some estimates) by four out of every five Fortune 500 companies. When those organizations invest in Teams Premium, they need experts who can maximize its value. Learn to optimize collaboration, and manage devices effectively to earn top-tier communications salaries.

Is the MS-721 exam hard?

The MS-721 exam can be challenging, but it’s manageable with the right preparation. Not only does the certification exam cover real-world planning, configuration, and troubleshooting in Teams, but it also tests vocabulary and familiarity with Teams premium features. This Microsoft Teams training has walkthroughs, demos, and realistic scenarios that will ensure you understand both the theory and the real-world skills the exam measures.

Is this collaboration systems engineer course considered entry level?

Although this course could probably be understood by someone with little experience in the field, the Collaboration Communications Systems Engineer Associate certification definitely isn't considered an entry-level credential. This course builds on experience with Microsoft Teams and enterprise communications systems, and assumes familiarity with Microsoft 365 services. Individuals with no experience configuring, managing and troubleshooting Teams Phone may find the material of this course challenging.
