Key Microsoft Teams statistics 2026

  • Microsoft Teams has more than 320 million monthly active users, according to Microsoft's latest official figure (late 2023). Industry estimates now put the total above 350 million (UC Today, Dec 2025).


  • Microsoft 365, which includes Teams in most business plans, passed 450 million commercial paid seats in January 2026, up 6% year on year (Microsoft FY26 Q2 earnings).


  • Teams Phone reached 26 million PSTN users by December 2025, up from 20 million in April 2024, about 30% growth in 20 months (UC Today).



  • Microsoft 365 Copilot passed 30 million paid seats by June 2026, double the 15 million reported in January 2026 (Microsoft FY26 Q4 earnings).

User base and active users

Microsoft Teams reached more than 320 million monthly active users in its last official count, reported by Microsoft in late 2023. Microsoft has not released a newer Teams-specific figure since, so any number above that is an industry estimate. UC Today put the total above 350 million by December 2025.


The clearer growth signal now comes from Microsoft 365, which bundles Teams into most business plans. Microsoft 365 commercial paid seats grew from 446 million to more than 450 million in a single quarter, up 6% year on year, and Microsoft 365 revenue grew 17% year on year (Microsoft FY26 Q2 earnings, January 2026).

How people use Teams

153

Teams messages per worker, every weekday

2 min

Between interruptions from meetings, emails or notifications

57%

Of meetings are ad hoc, called with no invite

117

Emails received per worker, per day

  • Nearly 1 in 3 meetings now span multiple time zones, up 35% since 2021.
  • Meetings after 8pm are up 16% year on year.
  • 11am is the most overloaded hour of the working day.

This is the environment UK businesses are managing, and it is why answering and routing calls cleanly inside Teams matters more than it did even two years ago.

Microsoft Teams Phone statistics 2026

  • 26 million Teams Phone PSTN users by December 2025, up from 20 million in April 2024 (UC Today).


  • About 6% of Teams users use Teams Phone for external calling (Cavell Group).


Teams Phone is growing fast, but at only around 6% of Teams users it is still heavily under-penetrated. For most businesses the chat and meeting side of Teams is embedded, while the phone line is still on an older, separate system. That gap is the opportunity. Adding calling to Teams through Direct Routing or Operator Connect lets a business keep its existing numbers and run calls, queues and voicemail inside Teams.

AI, Copilot and agents in Microsoft Teams

  • Microsoft 365 Copilot grew from 15 million paid seats in January 2026 to more than 30 million by June 2026, with net seat additions more than doubling quarter on quarter (Microsoft FY26 Q4 earnings).


  • Microsoft says Copilot's weekly engagement is now comparable with Outlook and Teams.


  • Active agents in Microsoft 365 grew 15 times year on year, and 18 times in large enterprises (2026 Work Trend Index, 20,000 workers across 10 markets including the UK).


  • 19% of Copilot conversations are about collaboration, and 49% support cognitive work such as analysis.


  • Only 26% of AI users say their leadership is clearly aligned on AI.


AI is moving from chat into calls. The same shift that put Copilot into Teams messages is now reaching the phone line. Our Agent AI Assist adds AI call handling and assistance to your phone system, and works across Yeastar and Cisco Webex. For a wider view, see our AI phone systems pages.

Industry and sector adoption

Teams and Microsoft 365 adoption now reaches some of the largest organisations in the UK and worldwide. In the healthcare sector, NHS England is rolling out Microsoft 365 Copilot to 505,000 clinicians and staff (Microsoft FY26 Q4 earnings call, July 2026).


Large enterprise rollouts include EY (400,000 staff), KPMG (276,000 or more) and HSBC (200,000), each deploying Microsoft 365 and Copilot at scale.
