Disable Copilot as a Microsoft 365 Admin
If you're an IT admin looking to block Copilot across your Microsoft 365 tenant, here’s exactly how to do it via the Integrated Apps settings in the Admin Center.
1. Sign in to Microsoft 365 Admin Center
Use your Global Admin or AI Admin credentials to log in at admin.microsoft.com.
2. Navigate to Integrated Apps
Go to Settings → Integrated apps.

3. Search for Copilot
Use the Search box to search for Copilot under Available Apps

4. Block the Copilot App
Find the Copilot app in the list. Click it and choose Block. This blocks the app tenant‑wide across Outlook, web, desktop, mobile. When it is blocked here it means no user can access Copilot from anywhere in Microsoft 365.

5. (Optional) Fine‑Tune User Access
If you want only certain users to keep access, select Specific users/groups instead of blocking entirely. Then assign access only to those in your Copilot‑licensed group.

6. Wait for It to Take Effect
Settings may take up to 24 hours to roll out fully across your tenant. In my experience, it did take almost the full 24 hours before it disappeared from Microsoft 365 for users.
