Fix Microsoft Copilot Error E010028 on Android and iOS
Question details
The user is unable to sign in to the Microsoft Copilot mobile app using a work or school account and receives an E010028 error code.
- Product
- Microsoft Copilot
- Device & OS
- Android and iOS
- Scenario
- Attempting to log in to the Microsoft Copilot app with a licensed corporate or educational account on a mobile device.
- Observed behavior
- A personal Microsoft 365 account signs in successfully, but attempting to sign in with a paid Microsoft 365 Copilot work account fails and displays error E010028.
Ensure your device has a stable internet connection and verify that you have your exact work or school account credentials, including access to any required multi-factor authentication (MFA) methods.
Verify Copilot License and Organization Policies
Use this solution to ensure your enterprise account has the correct permissions and licenses to access Copilot on mobile devices.
Error E010028 frequently occurs when a work or school account lacks the specific Microsoft 365 Copilot license, or when the organization's mobile device management (MDM) policies block mobile access.
Log in to your Microsoft 365 portal on a web browser and navigate to your account settings to verify that a 'Microsoft 365 Copilot' license is actively assigned to you.
Contact your IT department to confirm if organizational policies (like Microsoft Intune) allow the use of the Microsoft Copilot app on personal or company-issued mobile devices.
Clear App Data and Reinstall
Use this method to resolve corrupted login sessions or outdated app cache data causing the sign-in failure.
Escalate to Your IT Administrator
If troubleshooting fails and multiple devices are affected, the issue may require intervention from a Microsoft 365 Administrator.

Frequently Asked Questions
Why do I get error E010028 on my work account but not my personal account?
Error E010028 typically points to enterprise licensing issues or strict mobile device management (MDM) policies enforced by your organization. Personal accounts bypass these organizational restrictions, allowing for a successful sign-in.
Does Microsoft Copilot require a specific license for mobile app access?
Yes. While basic Copilot functionality might be available to consumers, using it with corporate data requires a designated Microsoft 365 Copilot license, and sometimes specific Azure Active Directory configurations set by your IT administrator.
How do I clear the Copilot app cache on an iPhone or iPad?
Apple's iOS does not offer a built-in button to clear app cache in the Settings menu for most apps. To completely clear the Copilot data on iOS, you must delete the app entirely from your device and download it again from the App Store.
What should I do if clearing the app data doesn't fix the E010028 error?
If clearing the data and reinstalling the app does not resolve the error, the problem is likely on the tenant side. You must contact your IT administrator to verify your license assignment and submit a support ticket to Microsoft.
