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 All,

    I'm fairly sure this fix has been posted here already but I thought I'd confirm it again here in case it helps anyone else.  I have had about 10 machines with this problem now, always triggered by a recent update to 2004 or 20SH. I've tried pretty much everything that has been suggested on this thread and I've got some mostly working, only for them to get worse with the next update.

    Replacing the users Windows profile is the only thing that has fixed it and it has stayed fixed! It has fixed the issue every time I have done it.  

    My husband works for an MSP and has seen this a lot he has also found that this fix consistently works.  I know it's awkward, and there is some work to be done to make the user at home again, but it really is worth it.

    Good Luck everyone!

    I'm wondering if that's the case - it seems to be ok this morning

    Hello

    Are you referring to the User Mail Profile, or the Windows Profile?

    Thanks

    Laura,

    if you are referring to the Outlook profile, I have tried that workaround too, but it didn't work

    Hopefully, it will be solved in the next update by Microsoft
