By making use of WebView2, we can more easily provide your users with Office features that look and feel the same across device platforms. In turn, this consistent experience helps your users to learn and use those features without having to learn the nuances of Office on each device platform. For example, by using WebView2, the Room Finder feature will look the same when using Outlook on a device running Windows and when using Outlook on the web. Office Add-ins will also start relying on WebView2.

Microsoft Webview2 Download

WebView2 requires that Microsoft Edge WebView2 Runtime be installed on the device running Office. If WebView2 Runtime isn’t installed on the device, your users won’t be able to make use of the Office features that rely on WebView2.

Therefore, starting on April 1, 2021, WebView2 Runtime will be installed on devices running Windows and that have Version 2101 or later of Microsoft 365 Apps installed.

Important

• WebView2 Runtime doesn’t install Microsoft Edge (full browser) on the device and doesn’t require Microsoft Edge to be installed on the device.
• When WebView2 Runtime is installed on the device, no change is made to the user’s default browser selection.

WebView2 Runtime installation

WebView2 Runtime will be installed starting on April 1, 2021. Only devices that are running Windows and that have Version 2101 or later of Microsoft 365 Apps installed are affected. If WebView2 Runtime is already installed on the device, WebView2 Runtime will be updated to the latest version, if needed.

Note

The installation of WebView2 Runtime is a separate process from the normal updates to Office provided by Click-to-Run. The installation won't happen as part of an Office update, but will happen at a different time. The timing of this installation isn't configurable by an admin.

To benefit from the new or improved Office features or add-ins that rely on WebView2, no action is required on your part. We recommend that you allow WebView2 Runtime to be installed.

After installation, you’ll see an entry for Microsoft Edge WebView2 Runtime under Control Panel > Programs > Programs and Features.

If you need to postpone the installation of WebView2 Runtime or your organization has specific limitations regarding deploying it, you can prevent the automatic installation of WebView2 Runtime on devices in your organization. But, if you don't allow WebVew2 Runtime to be installed, then Office features that rely on WebView2 won't be available on those devices.

To prevent the automatic installation of WebView2 Runtime, sign in to the Microsoft 365 Apps admin center (https://config.office.com) with an admin account. Then, go to Customization > Device Configuration > Modern Apps Settings. Select Microsoft Edge WebView2 and then clear the Enable automatic installation of WebView2 Runtime check box.

Note

Clearing the check box won’t remove WebView2 Runtime from devices on which it has already been installed. Only new installations of WebView2 Runtime are prevented.

Webview2 Runtime Installer

If you want to deploy WebView2 Runtime to devices in your organization on your own schedule, you can download it from https://developer.microsoft.com/microsoft-edge/webview2/#download-section. You should use either the Evergreen Bootstrapper or the Evergreen Standalone Installer, depending on your deployment needs.
