Fix “Your computers Trusted Platform Module has malfunctioned”

Configurare noua (How To)


Outlook with Office 365 account keeps prompting for password. After entering it, an error pops up “Your computer’s Trusted Platform Module has malfunctioned. If this error persists, contact your system administrator with the error code 80090030. It affects Outlook login only.



Log into the laptop with a different user account (an account other than the one which is displaying the above error)

  • Open File Explorer (Windows Key + E)
  • Click on the View tab
  • Tick Hidden Items

Navigate to the following location where **User** is a variable and the folder name will be of the user account which is having the issue C:\Users\**User**\AppData\Local\Packages\

  • Rename or delete the folder Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
  • Log out of the current user account
  • Log back into the user account that was having the TPM error and Windows will automatically create a new Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy folder
  • Open Office apps and you will now be able to authenticate successfully.
