Fix Microsoft Teams Error Code 80090016

From time to time I have seen error code 80090016 (Your Computer’s Trusted Platform Module has malfunctioned) when attempting to authenticate with Microsoft Teams(desktop version).
I was able to resolve this issue by getting windows to recreate the AAD Broker folder using the steps below.


  1. Log into the laptop with a different user account (an account other than the one which is displaying the above error)
  2. Open File Explorer (Windows Key + E)
  3. Click on the View tab
  4. Tick Hidden Items
  1. 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\
  2. Rename or delete the folder Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
  1. Log out of the current user account
  2. Log back into the user account that was having the TPM error and Windows will automatically create a new Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy folder
  3. Open Teams and you will now be able to authenticate successfully
