Harvey, which specializes in legal research, contract analysis, due diligence, and deal management workflows, will integrate with Microsoft 365 and Microsoft 365 Copilot as part of the expanded partnership. The companies had already committed to a substantial Azure cloud arrangement in 2025 before Microsoft's roughly 2,000-person legal team became a customer. The scope of Harvey's deployment within CELA and specific implementation timelines remain undisclosed.
The adoption carries symbolic weight. Microsoft is simultaneously pushing its own Copilot products aggressively into enterprise legal workflows while choosing a specialized third-party legal AI tool for its own legal department. For Harvey, the endorsement validates the market thesis that specialized legal AI platforms retain distinct value even within major AI infrastructure companies. For in-house counsel evaluating legal AI tools, the decision signals that point solutions designed specifically for legal work may outperform general-purpose AI assistants on core legal tasks.
