Microsoft 365 Copilot: what it can (and cannot) do by role

When we talk to a client about M365 Copilot, the conversation usually starts with "and what can it really do?". The honest answer depends on the role. This guide summarizes what we have seen work (and not work) in production.

Sales

• Long email thread summaries with recurring customers. Works very well.
• Proposal draft from a Word brief. Always needs human review.
• Customer meeting prep: summarizes emails, Teams, recent proposals. Good return.

HR

• Job description draft from bullets. Acceptable with editing.
• Climate survey summary with open comments. Good if the dataset is from M365.
• 1:1 feedback analysis from notes. Requires care with privacy.

Marketing

• Email rewrites in different tones. Works well.
• Copy variant generation for landing pages. Needs review and A/B testing.
• Market research summary. Limited: web lookup uses Bing and falls short in LATAM.

IT

• Ticket and post-mortem summaries. Good for managers, not for technicians.
• Runbook generation from previous documents. Acceptable as first draft.
• Technical documentation search: totally depends on knowledge base quality.

Finance

• Monthly report summaries. Good for narrative, not exact numbers.
• Variation analysis drafts. Do not trust without ERP validation.
• NEVER delegate to Copilot: reconciliations, closes, tax calculations. Silent error risk.
