Microsoft Outlook Exchange Error 80090016

You may receive an Outlook error that is labeled 80090016 after a clone to a new computer or a system board replacement. The error verbiage is "Your computer's Trusted Platform Module has malfunctioned. If this error persists, contact your system administrator with error code 80090016"

The system board change is causing the Office licensing and Outlook Exchange authentication to fail because the folder generated by those applications no longer matches the authentication tokens that are generated by the original Trusted Platform Module (TPM) chip.

Note: Do this with the affected user account logged off.

TPM Solution

Rename the following folder:


Open File Explorer

Browse to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC

Copy the contents of NGC into a new folder and leave NGC empty.


Note: If admin-related errors do not allow access to a folder for editing the following steps can be taken.

  • Browse to: C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft
  • Right-click the NGC folder and Select Properties.
  • Select the Security tab and click Advanced.
  • Click on the Change option on the top.
  • Enter the Admin Username under the object name box and click Ok.
  • Select the check box next to "Replace owner on sub containers and objects" and select Apply.
  • Click "Yes" on the prompt to acknowledge the ownership change.
  • Once files have been moved into a new folder and the PIN reset, be sure to remove the additional Admin account permissions on the folder.
