# Accenture rolls out Microsoft 365 Copilot to all 743,000 employees in largest enterprise deployment to date _Tuesday, April 28, 2026 at 8:07 AM EDT · AI, Tech & Business · Latest · Tier 2 — Notable_ Microsoft is rolling out its Microsoft 365 Copilot AI assistant to all of Accenture's approximately 743,000 employees in what Microsoft has described as the largest enterprise Copilot deployment to date. The deal expands a prior commitment by Accenture to deploy Copilot to 300,000 employees and extends it to the company's full global workforce across more than 120 countries. The timing is commercially significant for Microsoft. Copilot is the company's highest-profile enterprise AI product, but only around 3% of its 450 million-plus Microsoft 365 enterprise users currently pay the $30 per month Copilot premium. Microsoft shares are down approximately 12% this year as investors question whether the AI investment cycle will produce revenue growth at the expected pace. Accenture's internal usage data, shared via Microsoft's Newsroom, provides the most detailed real-world Copilot performance figures published by any enterprise at scale. Among a 200,000-employee cohort that has been using Copilot for an extended period, monthly active usage reached 89%. 97% of employees said Copilot helped them complete routine tasks up to 15 times faster. 53% reported significant productivity gains. And 84% said they would miss the tool if it were removed. Tony Leraris, Accenture's CIO, said: "If Microsoft 365 Copilot weren't delivering real value, our people simply wouldn't be using it, our high adoption rate is what shows us that there is value." The rollout methodology is as notable as the scale. Accenture did not simply turn Copilot on for 743,000 people simultaneously. It started with a pilot of a few hundred senior leaders, scaled to 20,000 users, ran that cohort while refining data governance and access controls, then expanded in phases with a highly tailored change management programme that included one-on-one training for leaders, group sessions, and a structured internal community on Viva Engage where employees shared use cases. Leraris said: "Real value from AI investments like Copilot doesn't come from simply turning it on. It comes from investing in your people, helping them understand how to use it, how to trust it and how it fits into the way they work." The commercial by-product of the rollout is Avanade's D3 platform, a sales intelligence tool built by the joint venture between Accenture and Microsoft, which uses Copilot to aggregate proprietary internal data, industry context, and external sources into a real-time briefing for sales representatives. Avanade has rolled out D3 to 25% of its sellers, and active users are generating 43% more sales opportunities than colleagues not using the tool. ## Sources - [The Next Web](https://thenextweb.com/news/accenture-deploys-microsoft-365-copilot-to-all-743000) --- Canonical: https://techandbusiness.org/newswire/5HfN120UQvvCz6r9eXeudq Retrieved: 2026-04-28T16:29:44.939Z Publisher: Tech & Business (techandbusiness.org)
