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!

    My team and I have encountered the "80090016" TPM error many times. Come to find out, the DWORD key of "EnableADAL" needs to be added with a hex value of "0" in the registry under "HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common". After this you will need to shutdown (not restart) the computer and power it back up. You will then not encounter this error again.

    This is needed because of the new O365 "Modern Authentication" requirements. O365 and Outlook version 2016 and later require this registry key. You can also deploy it in your network using GPO. That way during a migration you do not get halted by this error.

    George,

    Just create a new user profile.  That's what I did and it seems to be working.

    I finally seemed to have resolved this issue by creating a new user profile on my system.  No errors, No need to re enter passwords.

    Nothing seem to work. I uninstalled the Windows update and same issues still, just not as bad. I can't restore my computer before the update because no restorenpoint was created so now I'm stuck putting my password in 5 times daily for outlook and still get the TPM error once or twice daily
