A device licence does not buy Copilot
Microsoft Learn's requirements page says Microsoft Copilot is not available with device-based licensing for Microsoft 365 Apps for enterprise. People still need a work or school account in Microsoft Entra ID, and Copilot experiences that use mail need an Exchange Online mailbox. A company new to AI can buy the wrong thing carefully, and still have a room of PCs where the button does nothing useful.
Count people, not machines
A shared device plan spreads the apps. It does not spread Microsoft Copilot. If the business case divides the Copilot price by the number of PCs, the denominator is wrong. The denominator is the person with an eligible base licence and, where you need the full experience, a Copilot licence. Chat has its own, wider eligibility.
The account is part of the price
Learn also says an Exchange Online mailbox is required for experiences that use email, calendar or meetings, and that Copilot is not available in a group mailbox. A licence assigned to a person with no mailbox will not produce the Outlook result someone has already promised.
Readiness before the purchase order
The FrontierOrg method, a fiction, puts licence reality in the discovery, including what is owned, what is enabled, and what is actually used. A SKU on the agreement is not evidence the prerequisite is true. Ask the prerequisite before you add seats.
Monday
Ask for a count of Microsoft 365 Apps licences that are device-based, and a count of Copilot licences assigned to people without an Exchange Online mailbox. Either number above zero changes the plan.
Who signed a rollout date that assumes every PC in the building is a Copilot user?

Where this note mentions FrontierOrg, that is a fictional method for rehearsing a decision. It is not a company, not a client, and not a case study.
