Microsoft 365 Family Shares With 5 People — But Copilot AI Is Owner-Only (2026 Limits Table)

If you are buying Microsoft 365 Family so that six people can share one AI subscription, there is one thing the official pages state plainly and almost no guide mentions:

The cloud storage and the Office apps are shareable. The AI is not.

Microsoft’s own support page puts it in a bold Important callout (read directly on 2026-08-24):

AI benefits are only available to the subscription owner and cannot be shared with others.

In plain terms: Copilot inside Word, Excel and Outlook works only for the single account that pays. The five people you share with get 1TB each and full Office — but no Copilot in the desktop apps.

The short version

• Free (copilot.microsoft.com): chat, web-grounded answers, page summaries in Edge. No sign-in required. Enough for most people.
• Personal / Family: unlocks Copilot inside Office, but for the subscription owner only, and with smaller allowances than most people assume.
• Premium: the highest limits plus two extra agents (Researcher, Analyst) — still owner only.

The official limits table

Most vendors keep “free quota” deliberately vague. Microsoft’s AI credits and limits page is a rare exception and publishes a per-feature table (the page states “Last updated: July 2026”; we read it on 2026-08-24):

The official table has one more row, Agents, reading “25 tasks per month shared amongst all agents” — but that cell is merged and not broken out per plan. We reproduce the wording as-is and do not guess which plan gets what.

A footnote that is easy to miss: Microsoft 365 Basic does not include advanced AI features.

Three things that actually decide the purchase

1. Family and Personal have essentially the same AI allowance

Read the table: voice 30 minutes, vision 10 minutes, 60 image credits — identical on Personal and Family. Family costs more and buys five extra Office seats with 1TB each. It does not buy more AI.

The only AI row where Family beats Personal is Audio Overview in Notebooks (6 uses/day vs. extensive use).

2. Sixty image credits is smaller than it sounds

Microsoft defines an AI credit like this:

asking Copilot to “summarize my inbox” would deduct one AI credit

So those 60 credits are not reserved for image generation. The official list of credit-consuming surfaces includes Designer, Create, Photos, Paint, Notepad, Word and Excel — summarizing your inbox once costs a credit. Sixty per month averages two per day.

3. A shared seat only gets web Chat

The free vs. paid comparison page is more specific:

If Microsoft 365 Family or Premium is shared with you, you can access Chat at microsoft365.com by signing in with the Microsoft account associated with your subscription. Other AI benefits, such as Copilot in the desktop apps are limited to the subscription owner.

Shared users get Chat on the web — which overlaps heavily with what the free tier at copilot.microsoft.com already does. In AI terms, the extra money spent on family seats buys close to nothing.

What the free tier actually does

Per the official page, Microsoft Copilot (free) at copilot.microsoft.com gives you chat for writing, brainstorming and summarizing; real-time web-grounded answers; and page summarization in Edge. Sign-in is not required, though signing in adds chat history, image creation, longer conversations and voice.

Microsoft describes free-tier capacity only as “subject to available capacity and limits” and publishes no numbers. Where the vendor publishes nothing, we publish nothing — we do not estimate a messages-per-day figure.

Pricing

Prices below come from our earlier verification records (Taiwan pricing read from microsoft.com/zh-tw on 2026-08-08; USD re-checked 2026-08-14, unchanged):

Premium costs NT$360 more per month than Personal (NT$4,320/year). By the table above, that buys 30 extra minutes of voice per day, 5 extra minutes of vision per day, removal of the 60-credit image ceiling, and the Researcher and Analyst agents.

The test is simple: will you regularly use Researcher or Analyst, and do you actually hit the 60-credit ceiling? If neither, Personal is enough.

One point still unresolved (stated honestly)

On the discontinued Copilot Pro, we hold two official statements from different dates:

• Our 2026-08-09 verification record: the official store page no longer mentioned Copilot Pro; the transition period ended 2026-08-01 and we removed the plan from our database.
• Microsoft’s “Introducing Microsoft 365 Premium” support FAQ, read 2026-08-24, still says that if you already have Copilot Pro you may keep that subscription or switch to Microsoft 365 Premium.

The reasonable reading is that new purchases are closed while existing subscribers keep their plan, and the FAQ addresses existing subscribers. Microsoft does not date-stamp that page, so we will not state how long existing subscriptions remain valid. If you still hold Copilot Pro, check your own renewal status under Services & subscriptions in your Microsoft account rather than trusting any guide.

Checking your remaining allowance

Microsoft’s stated method: open Services & subscriptions in your Microsoft account to see current feature limits and AI credit usage. You are notified when you hit a feature limit.

Pricing comes from our earlier official-site verification records (2026-08-08, 2026-08-14).

Note: during this check, the microsoft.com store pages returned a “Your request has been blocked” interstitial to our connection, while still returning HTTP status 200. All limits and terms here therefore come from the readable support.microsoft.com pages, with pricing carried over from dated records of earlier successful reads.
