The word on the street is that Outlook is wanting MFA. So either you have to turn on MFA or disable ADAL
Fix get them onto MFA or
Close Outlook
Open Regedit
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
Create REG_DWORD

Hi Sam,
Based on the error message, the issue is related to Trusted Platform Module(TPM). You need to check whether your TPM works correctly. You try to back up your data and clear TPM. It will reset your security processor to its default settings. For your reference:
For more details about TPM, you can follow the link below:

This is not advisable, and not in the interest in security for Microsoft Applications. Responses like this should have a warning on the cause and effect of this type of change.
I was able to fix this issue by disconnecting my Work account and then reconnecting it. I was receiving the exact same error message and I had tried clearing the TPM and other fixes to no avail.
Below are the steps I used to remedy the issue:
- Navigate to the “Accounts” section of the Settings app and navigate to the “Access work or school” page. Click the account you want to unlink and press the “Disconnect” button. Follow the prompts to complete the account removal process.
- Navigate to the “Accounts” section of the Settings app and navigate back to the “Access work or school” page. Click the "+" icon to associate an account.
- Enter your credentials and wait for the process to complete.
- Launch Outlook and all should be functioning properly.
Hello,
I have a Office 365 account and am experiencing the same issue with Outlook, but I cannot find the "Accounts" sectiona nd Settings app. Cany anyone help me? Can you send screenshots where to find this when I log into my Office 365 account online?
Thanks
I'm having the same issue on non Domain (Workgroup) PC's. Outlook 2016 connected to Office 365 and OneDrive for business.
It manifested itself initially with an Outlook error. Cannot start Microsoft Outlook. Cannot open the Outlook Windows. The set of folders cannot be opened.......etc.
I decided to create a new Outlook profile for the user and at this point got the error the OP posted.
I was able bypass the error and complete the creation of the new profile without issue. I have to say that nothing has changed on these PC's and that is the very first time I have seen anything related to TPM when setting up Outlook 2016. These PC's have been running Outlook 2016 for approx 8 months so strange that this occurs now.
