Microsoft 365 Copilot

by Microsoft · est. 2023

Microsoft 365 Copilot is the AI layer embedded across the Microsoft 365 productivity suite — Word, Excel, PowerPoint, Outlook, Teams, and SharePoint. Powered by OpenAI's GPT-4 models with access to the user's organisational data via Microsoft Graph, Copilot can draft documents in context, summarise email threads, generate Excel formulas and data analysis, create PowerPoint presentations from prompts, and surface relevant information from across the organisation during Teams meetings. For APAC enterprises that have made Microsoft 365 their productivity standard — the majority of mid-market companies in Singapore, Hong Kong, Malaysia, Taiwan, and Australia — Copilot is the de facto AI deployment because it requires no new infrastructure, no new vendor relationship, and no data migration. It operates on data that is already in Microsoft 365 under the existing enterprise agreement.

Don't get burned

Limitations to know

  • ! USD 30/user/month is a significant budget commitment — ROI calculation is essential before broad rollout
  • ! Quality varies significantly by application: Teams summarisation and Outlook drafting are strongest; Excel Copilot is less reliable for complex financial modelling
  • ! Requires Microsoft 365 E3/E5 or Business Premium — not available on legacy Office or entry-level M365 plans
  • ! Non-English language quality (particularly Bahasa Indonesia, Thai, Vietnamese) is improving but lags English performance
