Microsoft 365 Copilot · sub-product

Copilot Chat (Enterprise, work-grounded)

The reason to pay for Copilot at all; the only AI that legally sees inside your Microsoft tenant.

Consilix rank 8/10

What it is

The paid Copilot experience inside the Microsoft 365 web app, Outlook, and Teams that grounds answers in your tenant data: mailbox, OneDrive and SharePoint files, calendar, Teams chats and meeting transcripts. Permissions are enforced from Entra ID, so it cannot show a user content they could not already open.

Key features

Work IQ grounding across mailbox, files, calendar, Teams
Permission-aware retrieval, no training on tenant data
Inline citations back to the source file or message
Persistent chat history per user
Web grounding as an optional toggle

Best use cases

Find the last three emails from a named client and summarise their position
Pull every SharePoint document a colleague has touched on a project this month
Draft a follow-up email that references a Teams meeting transcript
Answer questions about your own policies and HR documents
Brief yourself on a meeting attendee before joining the call

Weaknesses

Underlying model trails ChatGPT and Claude on complex reasoning, coding, and long-form writing. Retrieval quality is only as good as your SharePoint hygiene, which for most UK SMEs is poor. Sometimes confidently cites the wrong document.

Pricing

GBP 24.70 per user per month on annual commitment (UK list, ex-VAT). USD 30 per user per month for Enterprise; USD 18 for the Business tier (under 300 seats). Price rises on first renewal after 1 July 2026.
