Hi @Hussain, Zakir,

Welcome to Microsoft Q&A forum. 

Thank you for reaching out and sharing detailed information including the screenshot. I can totally understand the importance of having Outlook to work as expected for your work basis. Based on your description, this typically indicates that the Teams cache is out of sync or that the existing WebView2 installation has a problem.

To resolve the issue, please follow these steps:

Press Windows + R at the same time and enter regedit.
Navigate to the following registry path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\
Under the Clients folder, find and delete the folder with the name: {F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}.

After deleting this registry folder, run the WebView2 installer to reinstall WebView2.
Once WebView2 is reinstalled, Microsoft Teams launched successfully without issues.

I hope this information is helpful. Please follow the steps above and let me know if it works for you. If not, we can continue working together to resolve the issue.

Thank you for your patience and understanding. If you have any questions or need additional assistance, please don’t hesitate to reach out so I can continue to support you. If you found the response useful, please consider marking it as accepted, as this may help other community members who are looking for similar guidance.

Hi @Hussain, Zakir,

Thank you for your response. If the device is in a corporate environment, and you cannot edit the registry key above, I would recommend following these steps to resolve the issue:

Clear New Outlook cache

Close the new Outlook app.

Open the Run dialog by pressing the Windows + R keys together.

Type or paste the following command in the Run box and click OK:

olk.exe --devtools

Be sure to include a space before the two dashes if typing the command manually.

The new Outlook will open (you may be prompted to sign in), and the DevTools window will also appear.

In the DevTools window, click the Application button on the toolbar.

Clear local storage cache. In the left pane, under the Storage section, find the https://outlook.office.com link under Local Storage. Right-click on this link and select Clear.

Clear cookies. Still in the left pane, locate the https://outlook.office.com link under Cookies, right-click on it and select Clear.

Close the DevTools window.

Manually reinstall the WebView2 Runtime

If clearing the cache doesn't work, the next best step is a clean reinstall of the WebView2 component.

Completely close Microsoft Teams.

Open Windows Settings > Apps > Apps & features.

Search for and select Microsoft Edge WebView2 Runtime. Click Uninstall.

After uninstalling, download the latest version from the official Microsoft page below. Use the Evergreen Bootstrapper.

Download page: Microsoft Edge WebView2 | Microsoft Edge Developer

Run the downloaded file to install the new version and restart your computer.

Contact Microsoft Support

If the issue persists after trying these steps, the best next step would be to have your IT administrator open a support ticket with Microsoft via the admin center. A technical support engineer can then initiate a remote session, review backend settings, and run diagnostics. If needed, they can escalate the case to specialized engineering teams who are well-equipped to perform advanced troubleshooting and provide targeted solutions.

As moderators, our primary goal is to provide helpful guidance and support through general troubleshooting steps. While we don’t have access to internal systems or administrative tools required to resolve account-specific or backend issues, we truly appreciate your understanding of these limitations. We genuinely hope the information we share helps point you in the right direction, and we're always here to assist as much as we can within our scope.

For guidance on how to request support in the admin center, please refer to: Get support - Microsoft 365 admin.   

I hope these steps provided helpful information. Please try these steps and let me know if they work or not.

If you have any further questions or need additional assistance, please feel free to reach out and let me know.

Thank you for your time and understanding. Wishing you a great day ahead.
