Why Microsoft 365 Copilot is not proof by itself
Microsoft 365 Copilot drafts mail, summarises threads, and rewrites the file of record. Activity that stays inside Microsoft’s admin and Purview views cannot explain ChatGPT, JAX in Xero, or Slack AI on the same engagement.
For law firms and professional services, Copilot is often the sanctioned path, which makes the missing multi-tool record more dangerous, not less. Reviewers assume “we use Copilot” means “we can show what Copilot did.” Those are different claims.
Proof on the Taigris row
Taigris does not replace Microsoft 365 Copilot. It puts that surface on the proof trail (source, user, system, policy, hash) with the rest of the toolbox.
- Source labelled as Microsoft 365 Copilot, not a generic LLM.
- User, time, and the action (draft, summarise, rewrite).
- Policy on the row, including when Copilot was the approved alternative to shadow ChatGPT.
- Hash-bound export alongside every other AI system in scope.
Customer-owned environment
Connector depth depends on the customer-owned environment and the access you grant. Proof stays in that boundary. This page describes product intent, not a guarantee of every vendor API.
