I don’t know when or how but Outlook 365 stopped opening links in emails. This happened both on my 2 Windows 11 machines (daily driver & canary) but not on my W10 laptop. All running build 17126.20132 Current Channel.
The difference? Well the two desktops had Edge Blocker set and the Laptop did not.
So a little googling and I found this setting:
The default is of course Edge! I’d recommend y’all set it to Default Browser if you haven’t already.
