Microsoft Copilot's missing manual, written in prompts

What it does This is a curated prompt library for Microsoft 365 Copilot, organized into 573 production-tested entries across 29 collections. Prompts are grouped by application—Outlook, Excel, PowerPoint, Teams—and by job function, from executive assistants to sales teams. The repository also includes role-specific guardrails and an import-ready CSV pack for IT admins who want to preload approved prompts into a tenant-wide library.

The interesting bit The project treats prompts as enterprise infrastructure rather than one-off tricks. It ships a 44-prompt organizational starter pack in Microsoft’s exact CSV import format, complete with the hard tenant limits Microsoft omits: the 1,000-prompt cap, the four-pin maximum, and the character-count gotchas that silently reject imports.

Key highlights

• 573 prompts spanning 331 role-specific entries for 20 business functions, plus 70 Outlook and 26 power-user collections
• Organizational import pack with 44 department-level prompts pre-formatted for Microsoft’s bulk CSV importer
• Explicit “Copilot Guardrails” for high-risk roles like executive assistants and commercial operations
• A clear-eyed comparison of Copilot versus ChatGPT, noting where enterprise safety filters, data access, and reasoning depth differ
• Microsoft’s CMO for AI at Work cited the repo as “battle-tested in production environments”

Verdict Worth bookmarking if you are rolling out M365 Copilot to a team and need vetted starting points. Skip it if you are looking for open-source tooling or non-Microsoft LLM prompts.
