Current-era Microsoft continuing to push the boundaries of consent.
Microsoft Edge is a good browser but for some reason Microsoft keeps trying to shove it down everyone’s throat and make it more difficult to use rivals like Chrome or Firefox. Microsoft has now started notifying IT admins that it will force Outlook and Teams to ignore the default web browser on Windows and open links in Microsoft Edge instead.
It also works just fine with Chrome, there’s an extension you need to install. It’s a Chromium feature they’re leveraging. I know this because we’re in the same boat as you. Unfortunately it doesn’t work with Firefox.
