How to fix Microsoft 365 activation error "Trusted Platform Module has malfunctioned"?

Issue: My Microsoft Office keeps prompting me to enter my password whenever I attempt to use my Office 365 account. When I do, I receive an error  “Your computer's Trusted Platform Module has malfunctioned. If this error persists, contact your system administrator with the error code 80090030.” How do I fix this?

Solved Answer

If you are a Microsoft 365 user and experiencing an activation error, such as “Trusted Platform Module has malfunctioned,” you are not alone. This error can occur on both Windows 10 and 11, preventing users from accessing Microsoft 365 applications, such as Word, PowerPoint, Outlook, and Excel. It can also be shown with specific error codes, e.g., 80090016, 80090030, 80284001, and others.

The Trusted Platform Module, or TPM, is a security chip that stores sensitive information like passwords, certificates, or encryption keys. The TPM also ensures that your system's bootloader is not tampered with, protecting it from malware.

If you're encountering the “Trusted Platform Module has malfunctioned” error, the first solution is to clear the TPM keys on your computer. This process can be done easily by accessing the Settings application in Windows. If clearing the TPM keys doesn't resolve the issue, you may need to disable specific Windows components.

It's worth noting that the recent Microsoft PC Health Check app may be causing this error. The app checks whether your PC is compatible with Windows 11 and may trigger it during the process.

In addition to the above solutions, resetting Microsoft 365 activation state, or deleting TokenBroker data, may also fix the issue. Among other solutions, you will also find how to re-connect to Microsoft Azure and enable Memory Integrity.

Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
