Pick Microsoft Teams if your company already runs on Microsoft 365 and you want chat, files, mail and meetings tied together for each team. Pick Zoom if meetings are the main job, you spend a lot of time with outside people on other tools, or you want its webinars, phone or contact centre products. Nothing here proves which one has better call quality.
Open your laptop and look at where your work lives. If your documents sit in SharePoint, your email runs through Outlook and your staff sign in with a Microsoft account, you're not really choosing a video tool. You're choosing whether to use the one that's already wired into everything else, or to bring in a separate platform alongside it. That's the honest frame for this comparison, and it matters more than any single meeting feature.
One sells meetings first, the other is a layer on top of Microsoft 365
Teams is less a meetings app than a way of organising work inside Microsoft 365. It's built on Microsoft 365 groups and Microsoft Graph, so when someone creates a team, a SharePoint site, an Exchange shared mailbox, a calendar and a OneNote notebook get created with it. Chat, meetings and calls sit on top of that structure. If you've ever wondered why a new team suddenly has its own files tab and inbox, that's why.
The other vendor has gone in the opposite direction. It started as a meetings company and has grown outwards into a whole work platform, with chat, phone, mail and calendar, whiteboard, rooms and webinars sitting next to meetings. So the two now look more alike than their names suggest. One grew out from meetings, the other grew out from documents and email, and they've met somewhere in the middle.
That's why a straight feature race doesn't help much. Both do video calls. The real question is which centre of gravity suits how your business already works.
Where they differ, line by line
| Area | Zoom | Microsoft Teams |
|---|---|---|
| Starting point | A standalone work platform where meetings is one product among chat, phone, whiteboard, rooms and more | A hub built on Microsoft 365 groups and Microsoft Graph, with each team tied to a SharePoint site and shared mailbox |
| Admin model | Lists apps and integrations with Microsoft, Google, Salesforce, ServiceNow, Oracle and Atlassian | Managed through the Teams admin center, with identities in Microsoft Entra ID |
| AI assistant | ZoomMate, My Notes and AI Services, plus an on-prem AI option | Copilot in Teams, Interpreter for multilingual meetings and Facilitator in meetings |
| Beyond meetings | Contact centre, workforce and quality management, webinars and events, Bonsai and BrightHire | Apps added from within Teams, Planner and Power BI ties, guest and external access |
| Developers | Video SDK, Meeting SDK, apps, Co-Browse, MCP and Realtime Media Streams | A development platform for building on the hub and adding third-party apps |
| Audiences | Pages split by small business, enterprise, IT, customer experience, education, healthcare and more | Documentation written for admins, plus a separate end-user help hub |
| Getting started | Free plan stated | Not stated |
The AI helpers inside the call
Both now put an assistant in the meeting. On the standalone platform it's ZoomMate and My Notes, with a wider set of AI Services, and the vendor describes the whole thing as an AI-first work platform. One detail stands out for cautious buyers: it lists an on-prem AI option, which may matter if your industry is wary of sending meeting content to the cloud.
The Microsoft side offers Copilot in Teams, plus Interpreter for multilingual meetings and Facilitator inside meetings. If you hold calls across languages, Interpreter is the one to read up on. Beyond those names, there isn't much more to say here, so treat this as a list of what exists rather than a judgement on which assistant writes better notes.
Who runs it, and who it's written for
This is where your IT setup should do the deciding. Teams is managed through the Teams admin center, and people sign in with identities held in Microsoft Entra ID. If you already have someone looking after Microsoft 365, they'll be at home straight away. Its documentation is aimed squarely at those admins, with a separate help hub for everyday users.
The standalone platform pitches itself more widely. Its pages split out small businesses, enterprises, IT teams, customer experience, education and healthcare, and it lists integrations with Microsoft, Google, Salesforce, ServiceNow, Oracle and Atlassian. That breadth suits a company that doesn't live inside one vendor's world, or one that meets clients who all use different tools.
The wider product range, and what developers get
If you only need meetings and chat, skip this section. If you run a sales floor, a support desk or regular events, it's worth a read. The meetings-first vendor now sells contact centre, workforce management and quality management, webinars and events, plus Bonsai and BrightHire. For developers there's a Video SDK, a Meeting SDK, in-meeting apps, Co-Browse, MCP support and Realtime Media Streams, which is a long list if you want to build video into your own product.
The Microsoft hub's extras look different. You add apps from within Teams, it ties into Planner and Power BI, and it has guest and external user access for people outside your organisation. There's also a development platform for building on the hub and adding third-party apps. It's less about selling you a phone system or a webinar product and more about pulling Microsoft 365 work into one window. If webinars are the main reason you're here, our guide to the best webinar software for running online events goes deeper on that one job.
Four questions to answer before you decide
- Do most of your files and emails already live in Microsoft 365? If yes, the hub will feel like part of the furniture.
- Do you spend more time on calls with clients and partners than with colleagues? A standalone meetings platform that plugs into lots of other tools may suit you better.
- Do you need webinars, a business phone line or a contact centre from the same vendor? Only one of these two sells all of those.
- Who'll manage it? An existing Microsoft 365 admin points one way, while a team with no fixed IT setup has more freedom.
If your answers are mixed, that's normal. Plenty of businesses run both, with one for internal work and the other for client calls.
If neither one suits
These four do overlapping jobs in different ways. For a longer list, see our roundup of video conferencing software worth comparing, or browse the alternatives to Microsoft Teams if you're mainly trying to move away from the Microsoft hub.
Google Meet
Best for: Video meetings inside Google Workspace, sitting alongside Gmail, Drive, Docs and Gemini.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Slack
Best for: Channel-based workplace chat with meetings, video chat, canvas and lists, plus Slack Connect for external partners.
Whereby
Best for: Simple browser video calling for individuals, teams and platforms; the vendor says it's European owned and privacy-first.
RingCentral
Best for: Business phone, messaging and meetings in one app, with links to LLMs such as ChatGPT and Claude per its site.

My advice for most businesses
If your company already runs on Microsoft 365, start with Teams. You'll get chat, files, mail and meetings tied together, managed by whoever looks after your Microsoft accounts, and there's little reason to add a second system just for calls. If meetings are the heart of what you do, you work with lots of outside people on other tools, or you want webinars, a phone system or a contact centre from one vendor, the meetings-first platform is the stronger fit. Call quality can't be settled from what either vendor publishes, so run a few real meetings on each before you move everyone over.

Frequently asked questions
Does Zoom have a free plan?
Yes, its site states a free plan. Check what's included before you rely on it for client meetings.
Is Microsoft Teams only for companies using Microsoft 365?
It's built on Microsoft 365 groups, and each team creates a SharePoint site, shared mailbox, calendar and OneNote notebook, so it makes most sense for businesses already on Microsoft 365.
Which one has better AI meeting notes?
Both include an assistant: ZoomMate and My Notes on one side, Copilot, Interpreter and Facilitator on the other. Nothing published settles which writes better notes, so try each with your own meetings.
Can I invite people from outside my company?
Teams supports guest and external user access. The meetings-first platform lists integrations with Microsoft, Google, Salesforce and others, which helps when your clients use different tools.
Which is better for webinars and phone calls?
The meetings-first vendor sells webinars and events, a phone product and a contact centre. The Microsoft hub leans on apps, Planner and Power BI rather than those products.
