Understanding Error 80090016
When working with Microsoft Teams, encountering error code 80090016 can be a hindrance to productivity. Let’s explore the specifics behind this error and its implications for Teams.
The Role of TPM in Error Code 80090016
Error code 80090016 is often associated with issues pertaining to the Trusted Platform Module (TPM) on users’ computers. The TPM is a dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices. When Teams attempts to leverage these security protocols and encounters issues accessing or utilizing the TPM, error 80090016 can arise, indicating a malfunction or miscommunication with this security component.
- Access the TPM management console via the Windows Run dialog by typing tpm.msc.
- Check the TPM status for any indicators of a malfunction or the need for additional steps such as clearing the TPM or updating its firmware.
Significance of Error Code 80090016 in Teams
Encountering error 80090016 in Teams signifies that there is a deeper problem with the credentials or a security component that Teams relies on. This error code often surfaces when the application attempts to access or refresh the user’s login credentials and is impeded, potentially due to corrupted cache files or issues with the TPM as mentioned earlier. It’s critical for the functionality and security of Teams that these components work correctly.
| Potential Causes | User Impact | Resolution Focus |

Common Causes and Solutions
Encountering error 80090016 in Microsoft Teams often indicates issues related to system permissions, credential management, or file corruption. We’ll guide you through the specific methods to tackle these problems effectively.
Issues with Microsoft.Aad.BrokerPlugin Folder
In some cases, the error can stem from the Microsoft.Aad.BrokerPlugin folder. This is tied to system permissions and can be rectified by ensuring the NGC folder has the correct permissions.
Problems Due to Stale Credentials
Stale or corrupted credentials can prevent proper authentication, leading to error 80090016. Credentials for MS Teams and other Microsoft services are stored in the Windows Credential Manager, and sometimes these need a refresh.
Corruption in Teams Cache Files
Corruption within MS Teams cache may also trigger error 80090016. Cache files that are outdated or corrupted can cause various issues, including this error message.
Advanced Troubleshooting Steps
In addressing the Microsoft Teams error 80090016, we may need to take more in-depth measures. These steps involve manipulating system settings that require precision and attention. Make sure to back up the registry before making changes to avoid any unintended system issues.
Modifying the Windows Registry
When Teams error 80090016 occurs, it often requires us to tweak registry settings. We can do so through the Registry Editor—a potent Windows tool that stores configurations. For instance, adjusting the ADAL (Active Directory Authentication Library) settings could resolve the issue.
- Press Win + R, type
regedit, and press Enter. - Navigate to
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity. - Locate the EnableADAL registry key and set its value to 0 to disable or 1 to enable.
Remember, incorrectly altering the registry can cause serious problems. Only proceed if you are comfortable with these steps.
Managing Office Application Credentials
Sometimes, clearing outdated or corrupt credentials for Office applications can resolve error 80090016. This involves accessing the Windows Credential Manager and removing the credentials linked to Microsoft Office.
- Open Control Panel and select Credential Manager.
- Look for credentials related to MicrosoftOffice16 and remove them.
This step can help reset the authentication process for Microsoft Teams, which might be necessary if the error persists.
Repairing or Reinstalling Teams
If none of the above steps work, repairing or reinstalling Teams may be the next course of action. You can repair Microsoft Teams through the **Apps & Features** settings in Windows, opting for a **Quick Repair** first, followed by an **Online Repair** if the issue remains unresolved.
Should repairs fail, doing a clean uninstallation and reinstallation of Teams ensures that all components are reset:
- Uninstall Teams via Apps & Features.
- Delete the residual files from
%appdata%\Microsoft\Teams. - Download the latest version of Teams and install it.
This process helps eliminate any corrupt installation files that might be causing error 80090016.
Preventive Measures and Best Practices
Guarding Your Security
We must always prioritize security to prevent issues like Microsoft Teams error 80090016. Maintaining security for Teams, particularly when integrated with work or school accounts, involves regular updates and careful management of user accounts.
| Update Regularly | Secure Your Account | App Management |
| Ensure that Teams and all related Office applications are up to date. | Use strong credentials and multi-factor authentication for your Office work or school account. | Only install Teams desktop app from trusted sources. |
| Apply the latest security patches for Windows 11. | Routinely check for any unusual sign-in activity. | Keep an eye on app permissions and integrations. |
| Consider enabling automatic updates for all Microsoft software. | Educate users about phishing and other security threats. | Remove unused applications that may interfere with Teams. |
Remember to verify the synchronization between Teams and Outlook. Inconsistencies between these applications can sometimes give rise to errors, including issues with sign-in or authentication problems.
In our best practices, we understand that the workstation plays a crucial role. An overlooked but simple step is to ensure the computer’s time, date, and timezone are correctly set, as these can lead to unexpected authentication errors with Microsoft Teams or other services.
Lastly, if troubleshooting is needed, it’s advisable to do it from an account with administrative privileges to perform the necessary changes without restrictions. By implementing these preventive measures, we can significantly reduce the likelihood of encountering error 80090016 and maintain a smoother Microsoft Teams experience.
