Microsoft Outlook Exchange Error 80090016

You may receive an Outlook error labeled 80090016 after a systemboard replacement. The actual error verbiage is "Your computer's Trusted Platform Module has malfunctioned. If this error persists, contact your system administrator with error code 80090016" (Figure 1).

Figure 1

The systemboard 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 generated by the original Trusted Platform Module (TPM) chip. The error is either from this or may be related to using a PIN to sign-in.

Solution

Below are steps for resolving the TPM or using a PIN for Sign-in:

TPM Solution

Rename the following folder:
C:\users\$dir\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

To:
C:\users\$dir\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy.old

Note: You need to do this with the affected user account logged off. You can log in as a different administrator or do this via network share.

After starting Outlook again you will need to re-enter your password. You may also get an organization prompt, select Yes to "Allow my organization to manage this device".

This method may throw the same TPM error once more but if you ignore it. Outlook should continue to load and will not show the error again.

Repair Your PIN & Picture Password Solution

• Open File Explorer.
• Browse to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC
• Delete everything in this folder.
  Note: If you cannot delete anything due to an administrator error, add .old at the end of the folder name.
• Go to Settings -> Accounts -> Sign-in Options
• Click Add a PIN and set your PIN.
• Delete and re-create the Account in question.
