Hello,
My name is EngineTyme, an Independent Advisor and a Microsoft user like you and I would be glad to help you.
I apologize for the inconvenience you’re facing with your university email and the error codes. Let’s tackle this step by step:
- Error Code 135011:
This error occurs when your organization has disabled the device you’re trying to activate Microsoft 365 Apps on. To resolve this, please follow these steps:
If the device was disabled in Microsoft Entra ID, an administrator with sufficient privileges can re-enable it from the Microsoft Entra admin center:
- Sign in to the Azure portal.
- Select Microsoft Entra ID > Devices.
- Search for the device using the username or device name.
- Select the device and then choose Enable. For more detailed instructions, refer to this link: https://learn.microsoft.com/microsoft-365/troubleshoot/access-management/error-135011-activate-m365-apps
If the device was deleted in Microsoft Entra ID, you’ll need to re-register it manually.
- Error Code CAA20003:
This error might occur if a user is not a member of the Active Directory (AD) group that licenses them for Teams. Once licensed, allow approximately 30 minutes for the sync from AD to the cloud. After that, the user should be able to log in successfully.
If you encounter any further issues, I recommend reaching out to your School IT administrator for further assistance.
