Error code 80090016 usually happens when the Windows security or PIN data becomes corrupted.

Fix: Sign out of your account, restart your computer, and reset your Windows PIN in Windows 10 or Windows 11 settings. In some cases, clearing the NGC folder (PIN data) or reconnecting your work/school account may also solve the issue.

I recently encountered the same error code 80090016 on my system and was able to resolve it by running the Windows Update Troubleshooter and then checking for updates. It's possible that an outdated Windows update is causing the issue. I also tried resetting the Windows Store and reinstalling the affected app, which seemed to resolve the problem for me. Maybe trying these steps could help others with this error.

Error code 80090016 on Microsoft Windows usually occurs due to corrupted login credentials or a problem with Microsoft Office authentication. To fix it, sign out of Office apps, clear cached credentials from Credential Manager, restart your computer, and sign in again. If the issue continues, deleting the Office identity cache or repairing Office from Windows settings can resolve the problem.
