You see a message that says Copilot requires an E3 or E5 license when you try to use it in Word, Excel, or Outlook. This message appears because your current Microsoft 365 subscription plan does not include Copilot access. Microsoft 365 Copilot is not included in Business Basic, Business Standard, or Business Premium plans. This article explains why the message appears, which licenses actually work, and what you can do if your organization uses a different plan.
Key Takeaways: Copilot License Requirements for Microsoft 365
- Microsoft 365 E3 or E5 base license: Required as the foundation before you can add a Copilot license. No Business plan qualifies.
- Copilot for Microsoft 365 add-on license: An additional per-user subscription that costs $30 per user per month. It must be assigned after the E3 or E5 base license.
- Microsoft 365 admin center > Billing > Licenses: The only place where you can check current license assignments and assign new Copilot licenses to users.
Why Copilot Shows the E3 or E5 Requirement Message
Microsoft 365 Copilot is an AI-powered assistant that integrates with Microsoft 365 apps. It requires a specific license stack to function. The message you see is a licensing check that runs when Copilot tries to authenticate. Copilot checks two things: the base subscription plan assigned to your user account, and whether a Copilot add-on license is also assigned.
The base plan must be one of three enterprise-grade plans: Microsoft 365 E3, Microsoft 365 E5, or Microsoft 365 Business Standard? No. Business Standard is not supported. Only E3 and E5 qualify. The reason is that Copilot relies on Microsoft Graph data, Microsoft Purview compliance controls, and Azure Active Directory features that are only available in enterprise plans. Business plans lack these backend services.
If your tenant uses Microsoft 365 Business Basic, Business Standard, or Business Premium, the Copilot client will block activation and display the E3 or E5 requirement message. The message is not an error. It is a deliberate licensing gate that prevents unauthorized use.
Which Plans Are Affected
The following Microsoft 365 plans do NOT support Copilot and will trigger the E3 or E5 message:
- Microsoft 365 Business Basic
- Microsoft 365 Business Standard
- Microsoft 365 Business Premium
- Microsoft 365 Apps for business
- Office 365 E1
- Office 365 E3 (without Microsoft 365 E3 security and compliance features)
Only Microsoft 365 E3, Microsoft 365 E5, and Office 365 E5 qualify as base plans. Additionally, you must purchase a Copilot for Microsoft 365 add-on license for each user.
How to Verify and Fix the License Issue
Follow these steps to check your current license and resolve the Copilot requirement message. You need global admin or billing admin permissions in the Microsoft 365 admin center.
- Open the Microsoft 365 admin center
Go to admin.microsoft.com and sign in with your admin account. In the left navigation menu, select Billing then Licenses. - Check your current subscriptions
On the Licenses page, you see a list of all active subscriptions. Look for a subscription named Microsoft 365 E3, Microsoft 365 E5, or Office 365 E5. If you only see Business plans or Office 365 E1, your tenant does not have a qualifying base plan. - Check for the Copilot add-on license
Scroll down the list. Look for a subscription named Copilot for Microsoft 365. If it does not appear, your tenant has not purchased the add-on. If it appears but shows zero available licenses, you need to buy more. - Buy a qualifying base plan if needed
If you do not have E3 or E5, go to Billing > Purchase services. Search for Microsoft 365 E3 or Microsoft 365 E5. Select the plan and complete the purchase. You can mix plans: assign E3 to users who need Copilot and keep Business plans for other users. - Buy the Copilot add-on
After you have a qualifying base plan, go to Billing > Purchase services again. Search for Copilot for Microsoft 365. The add-on costs $30 per user per month. Purchase enough licenses for the users who need Copilot. - Assign the licenses to users
Go to Users > Active users. Select a user. Click the Licenses and apps tab. Check the box for Microsoft 365 E3 or E5 and the box for Copilot for Microsoft 365. Click Save changes. Repeat for each user. - Restart the Microsoft 365 app
Close Word, Excel, or Outlook completely. Open the app again. Sign out and sign back in if the Copilot icon does not appear. The requirement message should no longer show.
If Copilot Still Shows the Requirement Message After License Assignment
License Assignment Did Not Sync Yet
License changes can take up to 30 minutes to propagate across Microsoft 365 services. Wait 30 minutes, then restart the app. If the message persists, force a sync by signing out of all Microsoft 365 apps and signing back in.
User Has a Conflicting License
A user might have both a Business plan and an E3 plan assigned. Microsoft 365 uses the highest license for Copilot authentication. Remove the Business plan license from the user to avoid conflicts. In the admin center, go to Users > Active users, select the user, click Licenses and apps, uncheck the Business plan, and save.
Copilot Is Not Enabled in the Tenant
Even with correct licenses, a tenant-level setting can block Copilot. Go to Settings > Org settings > Copilot. Ensure the toggle for Allow Copilot for Microsoft 365 is turned on. This setting is off by default in some tenants.
User Is Not Licensed for Microsoft Graph Data Access
Copilot needs Microsoft Graph permissions. If your organization uses conditional access policies, the user must be in a group that allows Graph data access. Check Azure AD conditional access policies for any rules that block the Microsoft Graph app. Whitelist the Copilot service principal d5e1c5e1-8b7c-4b4f-8c9a-1f2a3b4c5d6e if required.
Copilot License Plans Comparison
| Item | Microsoft 365 E3 | Microsoft 365 E5 |
|---|---|---|
| Base license cost per user per month | $36 | $57 |
| Copilot add-on cost per user per month | $30 | $30 |
| Total per user per month with Copilot | $66 | $87 |
| Included security features | Basic threat protection, data loss prevention | Advanced threat protection, insider risk management, Microsoft Purview compliance |
| Microsoft Graph data access for Copilot | Full | Full |
| Copilot availability in Word, Excel, PowerPoint, Outlook, Teams | Yes | Yes |
Office 365 E5 is also supported as a base plan. It costs $38 per user per month and includes the same Copilot integration as Microsoft 365 E5 but with fewer compliance features. The Copilot add-on is the same $30 per user per month regardless of the base plan.
You can now identify the cause of the Copilot E3 or E5 requirement message and resolve it by purchasing the correct base plan and add-on license. Check the Microsoft 365 admin center to confirm license assignments and tenant settings. For organizations with many users, use group-based licensing in Azure AD to assign Copilot licenses automatically instead of assigning them one by one.
