How to fix WebView2 runtime error in Outlook?

When I try top open the new Outlook on Windows 11 I keep getting the following error: “Installation failed. The Microsoft Edge WebView2 Runtime is already installed for the system.” Then, when I click OK, I get one more: “There was a problem installing required dependencies. Please install the latest version of the Microsoft WebView2 runtime and reboot Outlook.”

Modern applications use Microsoft Edge WebView2 as an essential component which enables web-based content integration within their interface to show interactive elements independently of separate browsers. Increasing performance represents one key role of Microsoft Edge WebView2 since it serves Outlook to present email content while showing dynamic features and enhancing execution.

However, while it enhances functionality, some users have encountered issues where they are unable to launch or use the new Outlook due to a WebView2 error, preventing them from accessing their emails or navigating the interface properly.

Possible causes of the WebView2 error in New Outlook

This issue typically arises due to missing, outdated, or corrupted WebView2 runtime components, which Outlook relies on to function correctly. If the WebView2 runtime is not installed or has been damaged, Outlook may fail to load its web-based elements, leading to error messages.

Additionally, certain Windows updates or system conflicts can interfere with WebView2, causing compatibility issues that disrupt Outlook’s functionality.
