Microsoft Teams Statistics 2026: Users, Revenue & Market Share

Microsoft Teams has 320 million monthly active users — the last figure Microsoft officially disclosed, and still roughly eight times the estimated daily user base of Slack. That number matters because Teams ships inside most Microsoft 365 commercial plans, so its growth tracks the 446 million paid seats of the world's largest productivity suite rather than any standalone sales effort. This page compiles 58 Microsoft Teams statistics covering user growth, revenue, market share against Slack, Zoom, and Google Meet, meeting behavior, Teams Phone and Rooms, and Copilot adoption — each attributed to Microsoft earnings disclosures, the Microsoft Work Trend Index, Business of Apps, Statista, or Gartner.

User Numbers & Growth Timeline

Teams launched worldwide on March 14, 2017 as Microsoft's answer to Slack. Seven years later it is the default communication layer for the Microsoft 365 installed base — the same base tracked in our Microsoft 365 statistics roundup. One caveat applies to everything below: Microsoft stopped publishing regular Teams user counts after October 2023, so the most recent official figure is now several years old.

1. Microsoft Teams has 320 million monthly active users, per Microsoft's earnings disclosures — the company's most recent officially stated figure, given in October 2023.
2. Microsoft has not published a regular Teams user count since. Business of Apps estimates usage has held above the 320 million mark and continued growing through 2025, but no newer number carries Microsoft's confirmation.
3. Teams daily active users grew 11x in under two years — from 13 million in July 2019 to 145 million in April 2021 (Microsoft).
4. In the first three weeks of pandemic lockdowns, daily users jumped from 44 million to 75 million — a 70% increase between March and April 2020 (Microsoft).
5. Microsoft switched its reporting metric from daily to monthly active users in 2021, first citing 250 million MAU in July 2021 — which makes pre- and post-2021 figures not directly comparable (Microsoft earnings).
6. Teams stood at 280 million monthly active users in January 2023, meaning it added roughly 40 million users in the nine months before the final official update (Microsoft FY23 earnings).
7. The addressable base keeps expanding: Microsoft 365 counts 446 million paid commercial seats, and Teams is bundled into most of those plans (Microsoft earnings).
8. Dividing the two official figures puts Teams penetration at roughly 72% of paid Microsoft 365 seats — a derived calculation, not a Microsoft disclosure.
9. The Teams mobile app has passed 100 million installs on Google Play (Google Play public listing).

Revenue & Pricing

Microsoft does not report Teams revenue as a separate line item, so the best available figures are analyst estimates plus Microsoft's own published price list. The bundling question also changed materially in 2024, when regulators forced Teams out of the default Microsoft 365 suite.

10. Business of Apps estimates Microsoft Teams generates roughly $8 billion in annual revenue. Microsoft itself does not disclose a Teams figure — the product sits inside the Productivity and Business Processes segment.
11. That parent segment reported $69.3 billion in revenue for fiscal 2023, driven largely by Microsoft 365 commercial subscriptions that include Teams (Microsoft FY23 annual report).
12. In April 2024 Microsoft unbundled Teams from Microsoft 365 worldwide, after doing so in the EEA in 2023 under antitrust pressure — new commercial suites are now sold without Teams, with standalone Teams Enterprise listed at $5.25 per user per month (Microsoft).
13. Teams Essentials costs $4 per user per month, the cheapest paid tier, aimed at small businesses that do not need the full suite (Microsoft pricing page).
14. Teams Premium lists at $10 per user per month and adds intelligent meeting recap, advanced webinars, and watermarking on top of a qualifying base license (Microsoft pricing page).
15. The free tier caps group meetings at 60 minutes and 100 participants (Microsoft). Organizations that outgrow it can test the full suite through a Microsoft 365 free trial before committing.
16. For existing subscribers Teams remains bundled in legacy Business Basic, Business Standard, and E3/E5 suites — current Microsoft 365 plans list which SKUs still carry it (Microsoft pricing page).

Market Share vs Slack, Zoom & Google Meet

Market share in collaboration software depends heavily on what gets counted — suite bundling flatters Teams, while standalone video conferencing counts flatter Zoom. The figures below are analyst estimates, and the vendors' own metrics are not directly comparable, so treat cross-vendor rankings as directional.

17. Microsoft Teams holds an estimated 32% of the team collaboration software market, the largest single share (Statista and 6sense estimates; methodologies differ and exact figures vary by tracker).
18. Slack is the closest challenger at an estimated 19% share (Statista / 6sense estimates).
19. Slack's user base is estimated at 38–42 million daily active users by Business of Apps. Slack's last self-reported figure was 12 million DAU in 2019, and Salesforce has not resumed regular disclosure since the 2021 acquisition — the same transparency gap Microsoft now has with Teams.
20. Zoom's famous 300 million figure counts daily meeting participants, not unique users — one person joining five meetings counts five times. Zoom disclosed the number in April 2020 and corrected early reporting that had called it daily users (Zoom).
21. Google Meet holds an estimated 12% of the collaboration market, distributed mainly through Google Workspace bundling (Statista / 6sense estimates).
22. Comparing the last official counts, Teams' 320 million MAU is roughly 8x Slack's estimated daily user base — though MAU and DAU are different metrics, which is exactly why vendors pick the flattering one.
23. In standalone video conferencing trackers the picture inverts: 6sense places Zoom above 50% of that segment, ahead of Teams — evidence that Teams wins where the suite is already paid for, while Zoom wins deliberate video purchases.
24. Teams also absorbed its own predecessor: Microsoft retired Skype for Business Online in July 2021, converting that installed base to Teams (Microsoft).

Meetings & Usage Behavior

Microsoft's Work Trend Index, built on anonymized telemetry from Microsoft 365, is the richest public dataset on how people actually behave inside Teams. Its headline finding: hybrid work permanently raised the volume of digital collaboration. Our remote work IT statistics cover the infrastructure side of the same shift.

25. The number of weekly Teams meetings has tripled since February 2020, per the Microsoft Work Trend Index — and the volume never returned to pre-pandemic baseline after offices reopened.
26. 68% of meetings are now hybrid-capable, with at least one remote participant or a remote-join option (Microsoft Work Trend Index).
27. Time spent in Teams meetings rose 252% between February 2020 and February 2022 for the average user (Microsoft Work Trend Index 2022).
28. Chats sent per person grew 32% over the same two-year period — meetings did not replace messaging, both grew (Microsoft Work Trend Index 2022).
29. After-hours work measured in Teams rose 28% since March 2020, and weekend work rose 14% (Microsoft Work Trend Index 2022).
30. The average Teams user's workday span stretched 13% longer — about 46 minutes — between March 2020 and early 2022 (Microsoft Work Trend Index 2022).
31. 42% of meeting attendees multitask by sending an email or chat during the meeting (Microsoft Work Trend Index 2022).
32. Microsoft telemetry also identified a third productivity peak around 10 p.m. among a subset of Teams users, alongside the traditional morning and early-afternoon peaks (Microsoft Work Trend Index 2022).
33. The Teams app store lists more than 2,000 third-party apps — from Adobe to Zendesk — that run inside the client (Microsoft).

Teams Phone & Teams Rooms

Teams' quiet second act is telephony. Replacing a PBX with Teams Phone turns a chat license into a phone system, and the switch usually happens during a broader tenant move — which is why our Microsoft 365 migration services engagements increasingly include a calling workload.

34. Teams Phone has roughly 20 million PSTN users — people whose Teams client connects to the public telephone network — per Microsoft's 2023 disclosures.
35. The broader calling number is larger: Microsoft said in 2022 that around 80 million people use Teams Phone monthly when VoIP-only calls are included (Microsoft).
36. Microsoft reported Teams Rooms revenue more than doubled year-over-year during fiscal 2022 as offices re-equipped for hybrid meetings (Microsoft earnings commentary).
37. Microsoft added a free Teams Rooms Basic tier in 2022, covering core join-and-share features on certified hardware to lower the barrier for smaller rooms (Microsoft).
38. The upgrade runway is long: industry estimates cited by Microsoft put under 10% of the world's meeting rooms as video-enabled (Frost & Sullivan, cited by Microsoft).
39. More than 90 carriers participate in Operator Connect, Microsoft's program for wiring existing operator phone contracts into Teams (Microsoft).
40. Microsoft's own Calling Plans — the fully Microsoft-supplied PSTN option — are available in more than 35 markets (Microsoft documentation).

Copilot in Teams

Copilot's most concrete payoff so far is not writing documents — it is dealing with meetings. Microsoft's own telemetry ranks meeting recap as the single most-used Copilot capability. We track the broader rollout in our Microsoft Copilot adoption statistics and the wider industry picture in our AI adoption statistics.

41. Meeting summarization is the most-used Copilot capability across Microsoft 365, ahead of drafting in Word or Outlook (Microsoft Work Trend Index).
42. In Microsoft's controlled study, Copilot users caught up on a missed meeting nearly 4x faster than users working from raw recordings and transcripts (Microsoft Work Trend Index special report, 2023).
43. 70% of early Copilot users said they were more productive, and 68% said it improved the quality of their work (Microsoft Work Trend Index 2024).
44. 77% of early users said they did not want to give Copilot up once they had worked with it (Microsoft Work Trend Index 2024).
45. Copilot in Teams requires the Microsoft 365 Copilot add-on at $30 per user per month on top of a qualifying suite license (Microsoft pricing page).
46. Teams Premium offers a narrower alternative: intelligent recap at $10 per user per month covers AI meeting notes without the full Copilot license (Microsoft pricing page).

Enterprise & Education Adoption

Teams adoption is broadest at the two ends of the org chart: large enterprises that standardize on Microsoft 365, and schools that get Teams free with education plans. The fastest-growing segment in between is frontline workers on mobile devices.

47. More than 1 million organizations use Microsoft Teams as their default messaging platform (Microsoft).
48. Enterprise penetration came early: Microsoft reported 91 of the Fortune 100 were using Teams by 2019, two years after launch (Microsoft).
49. Frontline worker usage of Teams grew 400% between March 2020 and November 2021, the fastest-growing user segment Microsoft has disclosed (Microsoft Work Trend Index).
50. The frontline opportunity is the largest untapped pool: Microsoft cites an estimated 2 billion frontline workers worldwide, most of whom never had a corporate collaboration license (Microsoft Work Trend Index frontline report).
51. In education, Teams is included at no cost in the Office 365 A1 plan for accredited schools, which made it a default remote-classroom tool during 2020 school closures (Microsoft).
52. Microsoft said in 2020 that more than 100 million students and educators use Microsoft Education products, the funnel that feeds Teams for Education (Microsoft).
53. The hybrid expectation underneath it all: 73% of workers want flexible remote work options to continue, which keeps a persistent-chat-plus-video tool in every stack (Microsoft Work Trend Index 2021).

Outlook for 2026 and Beyond

The forward picture rests on three levers: the still-growing Microsoft 365 seat base, Copilot as a paid attach on top of Teams, and telephony replacing aging PBX estates. The main uncertainty is disclosure — until Microsoft resumes publishing user counts, every trend line past October 2023 is an estimate.

54. Microsoft 365 commercial seats have grown 7–8% year-over-year in recent quarters (Microsoft earnings), and because Teams attaches to those seats, its user base grows with the suite even without standalone wins.
55. Microsoft said nearly 70% of the Fortune 500 use Microsoft 365 Copilot (Microsoft FY24 Q4 earnings) — and since meeting recap is Copilot's most-used feature, Teams is where much of that spend lands.
56. Microsoft retired consumer Skype in May 2025 and pointed its remaining users to the free Teams client, consolidating consumer and business calling on one platform (Microsoft, announced February 2025).
57. Gartner predicted that in-person meetings would fall from 60% of all enterprise meetings to 25% as hybrid work settled in — a forecast that frames why room systems and hybrid-capable meetings keep growing (Gartner, 2021).
58. Business of Apps expects Teams revenue to keep climbing from its estimated $8 billion base as Premium, Copilot, and Teams Phone attach rates rise — though, like the user numbers, that trajectory is an estimate until Microsoft says otherwise.
