Hi Sam,
Based on the error message, the issue is related to Trusted Platform Module(TPM). You need to check whether your TPM works correctly. You try to back up your data and clear TPM. It will reset your security processor to its default settings. For your reference:

This did not help. The MSFT update forced on us causes Outlook to continually ask for a password. This did not happen before the update. None of these posted fixes work. You guys really need to test your stuff before you force these updates on us. Totally unacceptable that we have to take any action because you push bad software on us.
