Copilot Cowork reaches GA with usage-based costs
Reviewed by Helen Jones
Microsoft made Copilot Cowork generally available worldwide on 16 June 2026 for Microsoft 365 Copilot customers. Cowork requires a Microsoft 365 Copilot user subscription and then bills usage through Copilot Credits based on model use, context retrieval, tool calls and runtime. Microsoft also added tenant, group and user-level spending limits, usage alerts and reporting controls.
Before this release, most Copilot adoption work was still about choosing the right single prompt inside Word, Teams, Outlook or the Copilot app. The cost was mostly a licence decision and the output could usually be reviewed in one place. Cowork moves adopters into longer-running agent work where cost, context and review become harder to see. The practical adoption question is no longer "can a user prompt Copilot?" but "which tasks deserve credits, who checks the output, and when does an agent stop?"
Analysis
Leave Cowork off until your team has a one-page pilot rule: allowed tasks, credit cap, reviewer and evidence the output must include. Log each task's credits and corrections before you give access to a wider group.
