Microsoft Teams passed 115M DAUs in Q1, up 53% from April, as Microsoft works to capitalize on remote work trends

Context & Ripple Effects
Teams' user curve has been steepening all year: Microsoft reported 44M DAUs in mid-March, then 75M+ by the end of April as COVID lockdowns hit, and the Q1 figure of 115M extends that run to a 53% gain in six months. Before the pandemic, the trajectory was already competitive — 20M DAUs in November 2019 against Slack's 12M — but 2020 turned a enterprise-collaboration race into a mass-market one.
The Q1 number also lands between two strategic moves: Microsoft's March push to take Teams into the consumer market alongside Skype, and the following year's announcement of 145M DAUs plus Dynamics 365 integrations, which shows where the user growth was being monetized. This report is the midpoint of that arc — the moment Teams' pandemic surge became a durable lead.
First-order effects
- Microsoft's lead over Slack, which reported 12M DAUs in October 2019 when Teams claimed 20M, widens to roughly an order of magnitude — Slack's competitive position now rests on depth of engagement rather than user count.
- Teams' 115M users make it Microsoft's primary vehicle for remote-work demand, pulling usage across the consumer (Skype-adjacent) and commercial boundaries Microsoft drew in March.
Second-order effects
- Slack faces pressure to differentiate on integrations and workflow depth, since head-to-head DAU comparisons are no longer winnable against a bundled Microsoft 365 attachment.
- Skype's role narrows: with consumer Teams launched in March and Skype's own 40M DAU spike framed as pandemic-driven, Microsoft's two consumer chat properties now compete internally for the same stay-at-home usage.
Third-order effects
- If the pattern holds — growth sustained past the lockdown phase and tied into Dynamics 365, as the 2021 coverage shows — collaboration shifts from a standalone app category to a lock-in layer of the Microsoft cloud stack, with DAU scale as the moat.
- The consumer expansion signals collaboration vendors converging on the same market from both directions, setting up consolidation pressure on single-product competitors.
The trend: Workplace collaboration is consolidating around platform-attached suites, where pandemic-era user surges convert into durable ecosystem lock-in rather than temporary spikes.
