Microsoft 365 Copilot: Work IQ Guide

Key insights

• Microsoft 365 Copilot is widely adopted — used by more than 90% of the Fortune 500 — and Microsoft shipped over 400 new features in the past year.
  Microsoft adds new models like GPT-5, CUA, Sora 2, and supports Anthropic to match the right model to each task.
• Work IQ is the intelligence layer behind Copilot that helps the tool understand you, your role, and your company.
  It combines work data (emails, files, meetings), memory (preferences and workflows), and inference (insights and next-best actions).
• Work IQ personalizes Copilot inside apps like Word, Outlook, and Teams so suggestions fit your context and habits.
  It recommends the right agents based on your prompt and intent and learns from ongoing interactions to improve results.
• Custom agents let organizations build agents tuned to specific workflows while keeping controls in place.
  They enforce security and compliance — permissions, sensitivity labels, auditing, logging, and policy enforcement — and are available in Copilot Studio or via API.
• Recent updates bring Agent Mode into Office apps: Word (generally available), Excel (choose Anthropic or OpenAI models), and PowerPoint (available via the Frontier program).
  New Word, Excel, and PowerPoint agents create high-quality documents, spreadsheets, and presentations from Copilot chat.
• Overall, Copilot with Work IQ turns company knowledge into action by automating tasks, predicting next steps, and selecting the best model for each job.
  This improves productivity and helps teams work smarter with built-in governance and flexible licensing options.

Overview of the video

Microsoft released a YouTube video that outlines how Microsoft 365 Copilot is evolving and how a new intelligence layer called Work IQ powers it. The company says over 90% of the Fortune 500 already use Microsoft 365 Copilot, and the video highlights rapid feature development, noting more than 400 new features shipped in the past year. Additionally, Microsoft presented the expansion of model choices — including offerings from Anthropic and the latest tuned models such as GPT‑5, Sora 2, and computer use (CUA) — to match different business needs.

Furthermore, the clip explained that Microsoft aims to make Copilot a product people will rely on daily, and it emphasized integrating Copilot deeply into apps like Word, Outlook, and Teams. The video also announced that more advanced agent capabilities now appear in Office apps through Agent Mode, while new tools for custom agent development will reach developers via Copilot Studio and APIs. This news piece summarizes those developments and considers tradeoffs and practical challenges organizations will face.

How Work IQ functions

According to the video, Work IQ sits beneath Copilot as an intelligence layer that understands work context at three levels: data, memory, and inference. First, it ingests work data — emails, files, meetings, and chats — to map how tasks get done across an organization. Then it builds a form of memory that captures user style, preferences, habits, and workflows so Copilot can tailor outputs to individuals and teams.

Finally, Work IQ performs inference by combining data and memory to make connections and suggest next best actions, which goes beyond what simple connectors can achieve. For example, the video shows Copilot recommending the right agent for a given task based on intent, not just keyword matches. As a result, Microsoft frames Work IQ as an AI feedback loop continuously improving suggestions as users interact with Office apps.

Moreover, the system claims to understand not only organizational charts but also the more fluid “work chart” of relationships and workflows, thereby providing context-aware assistance. However, this richer understanding requires careful handling of signals so that Copilot remains accurate and respectful of user intent while avoiding overreach into private or irrelevant data.

Custom agents, security, and governance

One major announcement in the video was that organizations can now use Work IQ to build custom agents tuned to their unique workflows and business requirements. These custom agents can be grounded securely, respecting permissions, sensitivity labels, compliance controls, audit logging, and policy enforcement, which Microsoft says are available through Copilot Studio or APIs for pro-code development. Enterprises can adopt custom agents with a Microsoft 365 Copilot license or choose consumption billing, enabling flexible procurement models.

At the same time, Microsoft highlighted that deploying agents at scale calls for tradeoffs: stricter enforcement improves safety and auditability but can reduce agility and slow down deployment. Conversely, lighter governance speeds development but increases risk, so organizations must balance speed, control, and compliance when designing agent workflows. The video underscores that clear policy frameworks and robust monitoring are essential to maintain trust and meet regulatory obligations.

Model choice and tradeoffs

Microsoft’s inclusion of multiple models, such as those from Anthropic and OpenAI, plus internal offerings like GPT‑5 and Sora 2, was another focal point of the video. Offering model choice helps ensure that teams can select the best model for a given task — for instance, prioritizing safety, reasoning, or latency — but it also introduces operational complexity. Teams must weigh accuracy, cost, response time, and the model’s behavior under domain-specific prompts when choosing which model to use.

Moreover, model diversity can create consistency challenges: different models may give divergent recommendations for the same prompt, which can confuse users and complicate quality assurance. Consequently, organizations will need processes for model evaluation, A/B testing, and ongoing tuning to keep outcomes predictable while benefiting from specialized strengths. This approach requires investment in governance, telemetry, and change management to prevent fragmentation.

Adoption, challenges, and outlook

The video framed these updates as part of a broader push to make Copilot indispensable in daily work, with features like Agent Mode in Office apps and dedicated Agents for Word, Excel, and PowerPoint. While some capabilities are generally available, others appear via Microsoft’s Frontier program, indicating a phased rollout that balances innovation with cautious access. As adoption grows, the company must address practical challenges such as onboarding, user trust, and measuring business value.

In short, the YouTube video presents a vision of AI-enhanced work that is powerful yet complex, offering clear benefits alongside real tradeoffs. Organizations that balance governance, model selection, and user experience will likely gain the most, but they must also prepare for ongoing operational work in monitoring and tuning agents. Finally, Microsoft’s direction suggests continued rapid development, and businesses should watch for further updates as Copilot and Work IQ mature.
