Error code 80090016 Trusted Platform Module has malfunctioned.

When I try to add a new Office 365 email to my outlook I get the error below.   I think it's because of my "Work or school account" which I want to remove. I'm not sure how my email was signed up for this second account. I set up this computer for home use only, I won't be using any of the Microsoft Azure features. 

My question is, what will happen when I remove my “work account” and leave my Microsoft account?  Everything is backed up on Onedrive, I just don’t know what to expect because when I went to remove it, it warned me about losing data and settings.

Any help would be appreciated. Thank you!

    Hi,

    I have noticed the replies from WJfromATand PrzemyslawJanus that after using DisableADALatopWAMOverride and DisableAADWAM the issue was fixed but unfortunately this is not recommended and you can see the reason why in: 

    Disabling ADAL or WAM to fix Office sign-in or activation issues not recommended - Office 365 | Microsoft Docs.

    I have asked for an update and I will let you know. In the meantime, can you confirm if using those 2 registry keys as a workaround fixes the issue?

    Hello Aurelia,

    Do you mean trying all the steps, or just some?

    I can see this is impacting users in a big way. I depend on my PC to work and this error code 80090016 TPM is causing me a big inconvenience.  I am being logged out constantly from my accounts. This happened after a windows update which I have now removed but it hasn't solved the TPM issue.

    Can you please share any news about when this problem will be fixed? Can users fix it themselves?

    Some assistance would be greatly appreciated.

    Manuel

    Hi Manuel Carmona (info)"),

    I am still pending for an ETA. As I have mentioned above, I will definitely let you know and write on this forum once I have some news regarding this.

    The action plan has the workarounds that helped other users that reported this issue. I do understand that some of the steps are not easy to be performed. None of the steps helped you at least temporarily fix the issue?

    Hi Aurelia.

    I have done step 1 with the assistance of an Office 365 rep but  the remedy does not appear to work as office keeps requesting passwords. We cleared the accounts and added them up all over again.

    She referred me to this article: https://docs.microsoft.com/en-us/windows/security/information-protection/tpm/initialize-and-configure-ownership-of-the-tpm  

    The article above is published for IT professionals . I am nervous about changing anything that may render my laptop unusable. On the other hand , I work doing demos for clients, if I am locked out of my windows apps or outlook and unable to access meeting url's, there's a possibility I may end up losing my job.

    Is there more specific and accurate information Microsoft  could provide to remedy this problem?

    Best regards,

    Manuel
