Unfortunately many links in emails don't point directly to the destination but rather some cryptic link on some platform, to measure engagement and count clicks, which then redirects elsewhere, so by the time a page opens in the "Edge webview experience"
the URL has changed, and opening it in the default web browser might not result in the same experience. I have this issue with many invitation emails to surveys, where re-opening the survey in the browser from the webview won't work, because it needs to go
through the original link in the email. Also, some pages that open in the webview don't redirect automatically, like they do in the default browser. And then there are of course all the issues reported earlier by other people in this thread that prevent integration
with password management tools or plug-ins. In my opinion it is a very short-sighted approach to force us to use the Edge webview and not allow us to choose how email links are opened, and I for one don't care about Bing search capabilities - all I need is
the links in emails to open in my default browser, like any other email client supports it these days.
