We started facing TPM malfunctioning error when replacing motherboards on AutoPilot machines. No any suggested solutions helped. But we found an easy and effective solution. At least it worked in our case. Rejoining PC to domain. We have a hybrid AD. I did nothing with AAD account or Intune. Just join the affected PC to a workgroup, reset its account in on-prem AD, join the PC back to domain. It resolved the issue.

Vadim_Antonov Was the solution for me too! Thanks so much!
I tried renaming and deleting the AAD.Broker and Account.Control folders. I renamed the NGC folder, reset TPM, ran the SARA utility, and no success. Then I unjoined from the AD domain, rejoined, and signed in under the user's AD account. When opening the first O365 app I was prompted to register the device in O365. After that all the apps opened fine.
I will note that about two weeks ago the same error/issue appeared on a laptop that had just had the motherboard replaced, and all it took was renaming the AAD Broker folder to fix it.
Wish I knew more about the underlying connections between a device and O365 to figure out what is causing this, but at least now I have a growing list of things to try.
