> While this won’t affect the default browser setting in Windows, it’s yet another part of Microsoft 365 and Windows that totally ignores your default browser choice for links. Microsoft already does this with the Widgets system in Windows 11 and even the search experience, where you’ll be forced into Edge if you click a link even if you have another browser set as default.
The issue is that O365 is going to launch the link within the app (say Outlook) which is going to be running it on Edge, which lets them completely ignore whatever browser you would rather be using.
It's like every app on iOS that is shipping with a safari wrapper so it doesn't have to actually launch safari and give up its snooping abilities.
If you click a link in any other application, it will open whatever browser you've set up as your default in the system settings. Microsoft just went out of their way to explicitly always open Edge.
I couldn't even copy the links to paste them manually, as my organization disabled this. This is not OK.
On Linux, the "default web browser" is part of the XDG specification and available under the settings key `default-web-browser`. In the absence of such a standard at the DE level in Windows, it seems reasonable to me that developers would have to maintain a hardcoded candidate list of web browsers and their likely executable paths in the filesystem. And yes, of course MSFT would put Edge on the top of this search list, the same Apple would do Safari, or Google would do Chrome.
