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?

    Awesome!

    I used my old SSD in my new Laptop and wasn‘t able to reactivate the office365 license. Using the 2 registry entries it worked immediately after using my Office365 credentials.

    Perfect 👌

    Which registry entries did you change? Please advise
