The Register reported the change, and Microsoft's own November 2026 Partner Center announcement confirms it. Microsoft says it already uses fair-use limits for some Copilot features, such as image generation, for users without a Microsoft 365 Copilot license. Starting November 2, 2026, for organizations with 2,000 or fewer Microsoft 365 seats, and beginning November 9, 2026, for larger organizations, Microsoft is introducing fair use limits for additional Copilot Chat features and capabilities.
Who is affected, and where
The scope is narrow, and admins should get it right before the help desk tickets start:
- Affected: users without a Microsoft 365 Copilot license in commercial tenants using Copilot Chat on web, desktop, and mobile apps, signed in with work or school accounts.
- Not affected: people with a Microsoft 365 Copilot license. Microsoft says users with a Microsoft 365 Copilot license have access to additional features and capabilities.
- Unchanged: Copilot Chat remains included in Microsoft 365 subscriptions, and no admin action is required.
Microsoft is telling tenant admins through two Message Center posts. MC1536158 covers the smaller-organization wave that is already rolling out. MC1536163 covers larger tenants and says new Copilot Chat limits will start rolling out on November 9. Both posts say the same about the future: limits are currently used for some Copilot Chat capabilities and may expand to additional capabilities over time.
None of these announcements apply to personal Copilot accounts, education tenants or licensed users.
Section summary: This affects unlicensed commercial users on every Copilot Chat client. Smaller tenants started on November 2 and larger ones start on November 9.
What a limit looks like in practice
Microsoft's support page on Copilot Chat limits explains how it works, though it never gives a number. Availability can change with service conditions. Limits can change as the product changes and new features arrive. Because the limits vary, Microsoft doesn't publish numeric values. The Partner Center post adds that fair-use access can vary throughout the day.
When a user reaches a limit:
- The affected feature stops working for a while. Copilot Chat as a whole doesn't shut off.
- A message in the product tells the user when the feature will be available again. MC1536163 says Microsoft will be clear on the timeframe in product.
- Responses that are already being generated keep going.
- In most organizations, the message also has an upgrade option. Users can request a Microsoft 365 Copilot license from their admin, or buy one directly if the tenant allows self-service purchases.
Microsoft's support documentation also says hitting a limit is not an error or a product malfunction. Help desk staff should keep that in mind before anyone starts rebuilding user profiles to fix something that isn't broken.
What Microsoft does not say is just as important. It doesn't say which features are newly capped, whether limits reset on a fixed schedule, or what usage measure triggers them. Anyone quoting a daily prompt count is guessing.
Admins can't see the meter
This part is likely to annoy IT departments. According to the Message Center text, Microsoft sets and manages these limits. Admins can't view or adjust the limits. The Partner Center version adds that Microsoft won't publish specific limits because they are subject to change.
So admins get no per-user dial, no tenant-wide override and no report showing who is close to a limit. Microsoft gives two recommendations: tell the help desk, and review how license requests are handled.
Partners, on the other hand, do get a view. The Partner Center announcement points resellers to a "Users Experiencing Usage Limits" view in Microsoft's AI Business Solutions & Security Partner Experience (ASPX). It shows which customers have users reaching Copilot usage limits, and Microsoft suggests using it to decide which customers to approach about Microsoft 365 Copilot. In short, your reseller may know your users are hitting limits before your own admin console does.
Section summary: Admins can't change the limits or see them. They can control how users request or buy licenses afterward.
The sales pitch is in Microsoft's own wording
The Register pointed to the commercial motive, and Microsoft doesn't hide it. The partner announcement is headlined around the idea that these limits create an upsell conversation with your customers. It also says that when users reach Copilot Chat fair use limits, it might indicate interest in additional Copilot capabilities, such as Microsoft 365 Copilot and Microsoft 365 Copilot Business for small and medium businesses.
To be fair to Microsoft, fair-use throttling is common in AI services because inference costs real money. Microsoft also frames the limits as protecting reliability and service quality for everyone. Still, an unpublished limit that varies during the day, can't be seen by admins and comes with an upgrade button is a design that makes users ask for licenses. Whether IT ends up approving those requests or restricting Copilot Chat more tightly is something nobody can know yet.
This has happened before
The capped image generation Microsoft mentions dates back to MC1064749 in spring 2025. That notice said starting in late April 2025, users of Copilot Chat without a Microsoft 365 Copilot license will have a daily limit on the number of images they can generate. Even then, the daily limit for images is not publicly disclosed and is subject to change.
The free tier was trimmed again in 2026. Purdue University's IT newsroom reported that effective April 15, 2026, Copilot Chat users will no longer be able to access Copilot directly in Word, Excel, PowerPoint and OneNote. SAMexpert's analysis described that change as applying to unlicensed users at organisations with more than 2,000 Microsoft 365 seats. Microsoft also introduced labels: unlicensed users see "Copilot Chat (Basic)" whereas users with a Microsoft 365 Copilot license will see the "M365 Copilot (Premium)" label.
The pattern is clear. Microsoft gives Copilot Chat away with Microsoft 365 to build the habit, then gradually separates Basic from Premium. The November limits continue that approach.
| Change | Timing | Who | Published limit? |
|---|---|---|---|
| Image generation cap (MC1064749) | Late April 2025 | Unlicensed commercial users | No |
| In-app Copilot Chat removed from Office apps | April 15, 2026 | Unlicensed users (larger orgs per SAMexpert) | Not applicable |
| Expanded fair-use limits (MC1536158/MC1536163) | Nov 2 / Nov 9, 2026 | Unlicensed commercial users, all clients | No |
What admins should do this week
Admins can't change the limits, but they can decide what happens when a user clicks "upgrade." Here is a checklist based on Microsoft's licensing documentation:
- Brief the help desk. Tell support staff that a limit message is expected behavior with a retry time, not an outage. Ask them to stop troubleshooting clients for it.
- Decide on self-service purchasing for Microsoft 365 Copilot. In the Microsoft 365 admin center, go to Settings > Org settings > Services > Self-service trials and purchases, select the product, and choose Allow, Allow for trials only, or Do not allow. This path requires a Global Administrator. You can also use the AllowSelfServicePurchase policy in the MSCommerce PowerShell module. The policy is set per product, not with one tenant-wide switch, and changes can take up to 72 hours to apply.
- Set up license request handling. Go to Billing > Licenses > Requests to see pending and completed requests, including the product, requester, date and status. Requests are kept for 12 months. A User Administrator or License Administrator can approve all, some or none of the users in a request.
- Or send users to your own process. On the Requests tab, choose Connect your request process, select Use my organization's request process, then enter a message and an optional documentation link. Once that's on, the Requests tab stops showing new requests.
- Tell users the rules. Explain whether an upgrade request will be considered, who approves it and what counts as a business case. Users with a workflow blocked mid-afternoon will want an answer quickly.
The bottom line
Hidden limits that change throughout the day are hard to plan around. Admins have no control over the limits, and the Partner Center wording openly calls them an upsell opportunity. You can't stop Copilot Chat users from hitting the limits, but you can decide in advance what happens after they do.
