Microsoft Teams grew from more than 13 million daily active users in July 2019 to over 320 million monthly active users by December 2023. Microsoft’s published figures also show how the service expanded from workplace messaging into meetings, calling, apps, and large-scale events.

User growth and reach
Microsoft reported more than 13 million daily active users and more than 19 million weekly active users in July 2019. At that point, Teams was available in 53 languages and across 181 markets. These are Microsoft-reported historical figures for that month, rather than current usage estimates.
The service’s reported daily activity increased during the following year. Microsoft recorded 75 million daily active users in April 2020. Two-thirds of those users had shared, collaborated, or interacted with files on Teams. In October 2020, Microsoft reported 115 million daily active users.
Microsoft later used monthly active users for its large-scale adoption figures. Teams had nearly 250 million monthly active users in July 2021, according to the Microsoft FY21 Q4 earnings transcript. It had more than 280 million monthly active users in April 2023 and grew to over 320 million monthly active users by December 2023.
| Measurement period | Reported Teams user figure | Measurement type |
|---|---|---|
| July 2019 | More than 13 million | Daily active users |
| April 2020 | 75 million | Daily active users |
| October 2020 | 115 million | Daily active users |
| July 2021 | Nearly 250 million | Monthly active users |
| April 2023 | More than 280 million | Monthly active users |
| December 2023 | Over 320 million | Monthly active users |
The daily and monthly measures should not be treated as a single directly comparable series. They use different activity windows and were reported at different times. Still, the published milestones indicate a substantial increase in the scale Microsoft associated with Teams between 2019 and 2023.
By March 2024, Microsoft said Teams served over 320 million monthly active users across 181 markets. More than 75% of monthly active users were using the new Teams by then. Microsoft also reported that Teams was available in 44 languages in March 2024. The language figure differs from the 53-language figure reported in July 2019, so the two statements should be read as period-specific availability claims rather than a continuous trend.
Meetings and collaboration activity
Teams usage included substantial meeting activity during the April 2020 period highlighted by Microsoft. The company reported more than 200 million meeting participants in a single day. Those meetings generated more than 4.1 billion meeting minutes in that single day.
Microsoft also reported that Microsoft 365 users generated more than 30 billion collaboration minutes in a single day in the quarter highlighted in its October 2020 Microsoft 365 Blog update. That figure is for Microsoft 365 collaboration activity as described by Microsoft, not a Teams-only meeting-minute total.
The 75 million daily active users reported for April 2020 included a file-collaboration measure: two-thirds of those users had shared, collaborated, or interacted with files on Teams. The source does not provide a separate count of those users, so the proportion is retained without converting it into an unsupported headcount.
Teams meetings can support up to 10,000 attendees in the view-only meeting experience, according to Microsoft Learn. After around 900 users join a large Teams meeting, additional attendees enter in view-only mode. If that experience is disabled, attendance is limited to the first 1,000 attendees. Around 500 users trigger organizer notifications for the view-only experience in large meetings.
Meeting capacity depends on the plan and meeting mode. Microsoft Learn states that business and education SKUs on lower-tier plans can host up to 300 people. Higher Teams and Office 365 education and enterprise plans raise the meeting cap to 1,000 people. These limits are distinct from the 10,000-attendee view-only experience.
Teams Phone adoption and plans
Teams Phone reached nearly 80 million monthly active users in July 2021, while total Teams Phone calls surpassed 1 billion in a single month. In September 2021, Microsoft said Teams Phone was used by nearly 80 million users in more than 180 countries.
Microsoft reported 12 million Teams Phone PSTN users in June 2022. It described that total as nearly double the count from a year earlier. In April 2023, Microsoft said Teams Phone had added more than 5 million PSTN-enabled users during the preceding 12 months.
The available product figures show several different calling offers. Teams Phone Standard is priced at USD 10.00 per user per month on the Microsoft Teams Phone product page. Teams Phone with pay-as-you-go calling is listed at USD 13.00 per user per month for the US zone 1 offer. Teams Phone with Calling Plan is listed at USD 17.00 per user per month for the US zone 1 offer. Teams Phone with domestic and international calling is listed at USD 34.00 per user per month.
| Teams Phone offer | Published price or allowance |
|---|---|
| Teams Phone Standard | USD 10.00 per user per month |
| Pay-as-you-go calling, US zone 1 | USD 13.00 per user per month |
| Calling Plan, US zone 1 | USD 17.00 per user per month |
| Domestic and international calling | USD 34.00 per user per month |
The Calling Plan includes 3,000 outbound domestic calling minutes for the US, UK, and Canada, and 1,200 outbound domestic calling minutes for the rest of the world. The domestic-and-international offer includes 600 outbound international calling minutes for the US, UK, and Canada, and 600 outbound international calling minutes for the rest of the world.
Microsoft lists a 99.999% uptime SLA for Teams Phone Standard. The product prices and allowances are offer-specific figures; geography and plan selection affect how they apply.
Teams Premium and calling prices
Teams Premium launched with introductory pricing of USD 7 per user per month in February 2023. Microsoft’s February 2023 Microsoft 365 Blog announcement said the standard price returned to USD 10 per user per month on July 1, 2024. The introductory offer therefore belongs to a defined launch period, while the later figure is the stated standard price after that period.
The Teams Premium free trial lasted 30 days. A Teams Premium user also needed an existing Microsoft 365 or Office 365 license. Those requirements are separate from the price itself and matter when comparing the add-on with standalone communications products.
Teams supports up to 20 people in an audio or video call started from chat. A chat message is approximately 100 KB per post. These are product limits, not measures of average usage or adoption.
Meeting, team, and channel limits
An individual team can have up to 25,000 members. A shared channel can have up to 5,000 direct members and can be shared with up to 50 teams, excluding the parent team.
Private channels have a maximum of 250 members. Each team can have a maximum of 30 private channels, and that 30-channel limit is included within the overall limit of 1,000 channels per team. The member and channel figures describe different objects: a team-wide membership cap is not the same as a private-channel membership cap.
Teams meetings on lower-tier business and education plans can host up to 300 people, while higher Teams and Office 365 education and enterprise plans can host up to 1,000 people. Separately, the view-only meeting experience supports up to 10,000 attendees. Around 900 attendees is the point at which additional participants enter view-only mode in a large meeting, and disabling that experience limits attendance to the first 1,000 attendees.
The maximum meeting recording length is 4 hours or 1.5 GB. Teams stores meeting recordings that are not uploaded to Stream for 20 days. Teams meeting recordings expire 60 days after a one-time scheduled meeting time. These time limits refer to different recording and meeting-storage rules and should not be combined into one universal retention period.
Recordings and live events
Standard Teams live events supported up to 20,000 attendees and could run for 16 hours. A Microsoft 365 or Office 365 organization could run 50 standard live events simultaneously. Live events over 20,000 attendees required the Live Events Assistance Program.
The live-event figures are historical product specifications supplied by Microsoft Learn. Microsoft Learn stated that Teams live events were scheduled to be retired in July 2026, while support for already scheduled events was available through February 28, 2027. Those dates describe the published retirement schedule and the stated support window for events that had already been scheduled.
The live-event capacity should not be confused with ordinary Teams meeting capacity. A standard live event’s 20,000-attendee limit is higher than the 1,000-person cap on higher-tier standard meetings and the 10,000-attendee view-only meeting experience. Each figure applies to a different Teams event type and configuration.
