You need to enable Microsoft Copilot for your Microsoft 365 tenant before users can access Copilot in Word, Excel, PowerPoint, Outlook, Teams, and other apps. The feature is not turned on by default after licensing. You must complete several configuration steps in the Microsoft 365 admin center and assign licenses to users. This article explains the exact steps to enable Copilot, configure data access, and verify that the feature is working.
Key Takeaways: Enabling Copilot for Your Tenant
- Microsoft 365 admin center > Billing > Licenses: Assign Copilot licenses to individual users after purchasing seats.
- Microsoft 365 admin center > Settings > Org settings > Copilot: Enable the Copilot service and configure data source access for grounded responses.
- Microsoft 365 admin center > Users > Active users: Verify each user has the Copilot license applied and a supported Microsoft 365 plan.
What Copilot for Microsoft 365 Requires Before You Enable It
Copilot for Microsoft 365 is an AI-powered assistant that works across Microsoft 365 apps. It uses the Microsoft Graph to access your tenant’s data including emails, files, meetings, and chats. To enable Copilot, you must meet several prerequisites.
Your tenant must have one of the following Microsoft 365 plans: Microsoft 365 E3, E5, Business Basic, Business Standard, Business Premium, or Office 365 E3 or E5. Copilot requires an add-on license purchased per user per month. The add-on license is separate from your base Microsoft 365 subscription. You must have at least one base license seat for each user who will receive a Copilot license.
The admin who performs the configuration must have the Global Administrator role or the Billing Administrator role in the Microsoft 365 admin center. Users must have a Microsoft Entra ID account in the same tenant. Copilot uses Microsoft Graph data, so you must ensure that data access policies such as Conditional Access and Data Loss Prevention are configured correctly. Microsoft recommends enabling audit logging in the Microsoft 365 compliance center because Copilot uses audit logs for some grounding operations.
Supported Apps and Features After Enabling Copilot
Once enabled, Copilot appears in Word, Excel, PowerPoint, Outlook, Teams, Microsoft 365 Chat, and the Copilot pane in Edge. In Word, Copilot can draft, summarize, and rewrite documents. In Excel, it can analyze data and create charts. In Outlook, it can summarize email threads and draft replies. In Teams, it can summarize meeting transcripts and chat conversations. Microsoft 365 Chat acts as a central hub where users can ask questions across all their Microsoft 365 data.
Steps to Enable Copilot for a Microsoft 365 Tenant
Follow these steps in order. Do not skip the license assignment step because Copilot will not appear for users without a license.
- Purchase Copilot for Microsoft 365 add-on licenses
Go to the Microsoft 365 admin center at admin.microsoft.com. Select Billing > Purchase services. Search for “Copilot for Microsoft 365” and select the add-on. Choose the number of licenses you need and complete the purchase. Each user requires one license. - Assign licenses to users
In the admin center, go to Billing > Licenses. Select the Copilot for Microsoft 365 product. Click Assign licenses. Select the users you want to enable. You can assign licenses to up to 20 users at a time. Click Assign. Wait up to 30 minutes for the license to propagate. - Enable the Copilot service in org settings
Go to Settings > Org settings. Find Copilot in the list and select it. Toggle the switch to On. In the Data sources section, select which Microsoft Graph data Copilot can access. The default is all data sources. For tighter control, deselect specific sources like SharePoint or Exchange. Click Save. - Verify user license assignment
Go to Users > Active users. Select a user who should have Copilot. Check the Licenses and apps tab. Confirm that Copilot for Microsoft 365 appears in the list and is toggled on. If the license is missing, repeat step 2. - Install or update Microsoft 365 apps
Users must run the current version of Microsoft 365 apps. In Windows, open any Microsoft 365 app such as Word. Go to File > Account > Update Options > Update Now. Restart the app after the update completes. The Copilot icon appears in the app ribbon if the license and service are enabled correctly. - Test Copilot in a supported app
Open Word on a user device that has the Copilot license. A new Copilot icon appears in the top-right area of the ribbon. Click the icon to open the Copilot pane. Type a prompt such as “Draft a proposal for a new client.” Copilot should generate a response. If the pane does not open or shows an error, check the service health in the admin center under Health > Service health.
Common Configuration Issues After Enabling Copilot
Copilot icon does not appear in Microsoft 365 apps
The most common cause is a missing license or an outdated app version. Verify the user has a Copilot license assigned in Users > Active users > Licenses and apps. Also confirm the user has a supported base plan such as Microsoft 365 E3 or Business Premium. Update the Microsoft 365 apps to version 2311 or later. If the icon still does not appear, sign the user out of all Microsoft 365 apps and sign back in.
Copilot returns generic output instead of tenant-specific data
Copilot uses Microsoft Graph to access your tenant’s data. If the output is generic, Copilot may not have permission to read your data. In Settings > Org settings > Copilot, confirm that the Data sources section includes the correct sources. The default is all data sources. If you deselected SharePoint or Exchange, Copilot cannot read files or emails. Also check that the user has access to the data they are querying. For example, a user cannot ask Copilot to summarize a SharePoint file they do not have permission to view.
Copilot shows an error about licensing or service availability
This usually means the Copilot service is not fully provisioned. After you assign licenses and enable the service, wait up to 30 minutes. Check Health > Service health in the admin center for any advisories about Copilot. If the service shows a degradation, wait for Microsoft to resolve it. You can also check the Microsoft 365 message center for planned maintenance.

Enabling Copilot for your Microsoft 365 tenant takes about 30 minutes after you purchase licenses. You now know how to assign licenses, turn on the service, configure data sources, and verify that users can access Copilot in their apps. To further control Copilot behavior, explore the data source settings under Settings > Org settings > Copilot. You can limit Copilot to specific SharePoint sites or Exchange mailboxes. For advanced security, configure Conditional Access policies to require multi-factor authentication before Copilot can access Microsoft Graph data.
