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: Do this with the affected user account logged off. You can log in as a different administrator or do this using network share.
After starting Outlook again, you must reenter 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.

 

 

 

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.
