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!

    We are having this same issue. This is what fixed it for us. Create the following registry entries.

    [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity "DisableADALatopWAMOverride"=dword:00000001

    [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity "DisableAADWAM"=dword:00000001

    This did the trick for me!!!

    Hi Guys,

    TPM Malfunctioned - Error 80090016 - Keyset does not exist

    This one resolved my issue.

    1. Go to your settings
    2. Click Accounts
    3. Click the Access work or school
    4. Remove the email you're trying to access for Office365,Remote Desktop or what. (Work or school email)
    5. Re-add the email you remove and try logging in again without restarting the PC.

    Simple as that, it worked on my laptop, if you have trust issues restart the desktop or laptop and try it again.

    You can thumbs up if it works for you or thumbs down if not.

    • Hope it works on you guys as it works on me!

    This work for me. Thanks.

    I'm having the same issue for days now and I can't find a solution.

    I am on the phone with Microsoft support for hours and days and whatever tricks we tried do not seem to produce any outcome.

    Yep, i went through days of support. Was told in the end, no fix. Await update. Have to log into things maybe 20 times a day!

    Open Regedit.MSC with administrator account and navigate to :

    HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb

    Afterwards create DWORD (32-bit) Value Key

    Rename it with : ProtectionPolicy  and set value to 1

    Afterwards try to open affected 365 App it should force it log in page and enroll again. 

    At this stage Outlook,OneDriveshould work as expected.

    After researching this for a while - and finally trying out this solution... it was... actually a solution! Thumbs up! Thanks! 

    The images you posted did not come through.  Please try to repost as my previous posted solution did not "stick" and I'm back to logging in to my MS Windows and related apps each and every time I reboot.
