Microsoft is ending Claude Code access for employees in its Experiences and Devices division, which covers Windows, Microsoft 365, Outlook, Teams, and Surface, according to reporting by The Verge’s Tom Warren. Those teams are expected to complete the switch to GitHub Copilot CLI before the end of June.
The reported financial timing is a likely factor. Microsoft’s fiscal year closes June 30, and canceling Claude Code licenses ahead of that date would reduce costs as the company rolls into a new budget cycle. A Microsoft executive framed the decision publicly as the end of a structured benchmarking phase, saying the company’s goal from the start was to compare both tools in real engineering workflows.
The context matters here. Microsoft is simultaneously a reported $5 billion investor in Anthropic, the company that builds Claude. That investment posture and this internal-tooling decision now point in opposite directions, which is a clean signal that Microsoft treats Anthropic as a financial bet rather than a preferred internal vendor.
Warren’s reporting also notes that Claude Code had become popular inside Microsoft, with developers preferring it over Copilot CLI because of feature gaps in the latter. The shift is happening despite user preference, not because of it.
Developers at other organizations running Claude Code under Microsoft-procured agreements should check their licensing terms. If Microsoft is consolidating on Copilot CLI for cost reasons, that procurement pressure may surface in enterprise contract negotiations in the months ahead.
