ON24 vs Microsoft Teams: which webinar software is right for you?

The short answer: ON24 is deeper on marketing-grade branding and engagement data, while Microsoft Teams is stronger on reliability and reach inside an organization.

Core purpose. ON24 is built to run webinars as marketing programs, so its features go deeper on the audience-facing and data sides. Microsoft Teams is built for communication first, with event features that are strong on reliability and reach inside an organization.

Engagement and branding. ON24 offers Q&A, polls, and reactions, plus branded event consoles, interactive widgets, and personalization that tailors the experience per viewer. Microsoft Teams offers Q&A, polls, and reactions, and added meeting themes, email customization, and town-hall streaming chat to its Enterprise tier as of April 1, 2026.

Content reuse. ON24 keeps webinars discoverable on demand through its content hub.

Reporting. ON24 provides engagement scoring, behavioral signals, and AI analytics built for demand generation and meant to feed CRM and sales workflows. Microsoft Teams provides attendance reports, real-time event insights for organizers, and org-wide event reporting through the admin center.

Why it matters: The Teams update narrows the branding gap for internal events, but ON24 still leads on external, marketing-facing customization. Teams reporting is oriented toward operations and IT rather than pipeline attribution, while ON24 turns engagement into structured lead data.

The short answer: ON24 is built around marketing and sales tooling, while Microsoft Teams integrates most deeply within the Microsoft ecosystem.

Native CRM. ON24 connects to major CRM systems so engagement data can drive scoring, routing, and follow-up. Microsoft Teams works natively with Dynamics 365 for customer data, and other CRMs connect to Microsoft Teams through available connectors.

Marketing automation. ON24 connects to major marketing automation systems, a focus that is central to how ON24 is used. Microsoft Teams connects other tools through connectors rather than a built-in marketing data pipeline.

Productivity apps. Microsoft Teams works natively with Outlook for scheduling, PowerPoint Live for presenting, and the broader Microsoft 365 apps.

API and marketplace. Microsoft Teams has a large third-party app store that extends it beyond Microsoft tools.

Why it matters: If your CRM is Dynamics, Teams connects natively, but ON24 is the one designed to move webinar engagement data into marketing and sales systems.

The short answer: ON24 sells custom annual quotes through enterprise sales, while Microsoft Teams is priced per user and bundled with Microsoft 365.

Pricing model. ON24 has no published list pricing; its plans are custom annual quotes, bought through an enterprise sales conversation rather than a self-serve checkout. Microsoft Teams is priced per user and bundled with Microsoft 365 plans on an annual basis, so most organizations already have it.

Plans and tiers. ON24 quotes vary by tier, with no public tier pricing. Microsoft Teams has included advanced webinar, town-hall, and eCDN features that required Teams Premium with Teams Enterprise licenses since April 1, 2026.

Add-ons. ON24 add-ons feed into the custom quote. Microsoft Teams Premium still adds advanced meeting protection, branding, and intelligence, and the Microsoft Teams Attendee Capacity Pack is needed to scale past included attendee limits.

What drives cost. ON24 cost depends on tier, event volume, and add-ons, so the right figure depends on your program size. Microsoft Teams cost depends on the number of users on your Microsoft 365 license, plus any add-ons you need.

Which is cheaper for you: If you already pay for Microsoft 365 and mostly run internal events, Teams usually adds little or no extra cost; ON24 is a separate enterprise budget line.

Pricing changes, so confirm current figures with each vendor.
