When you open Chrome, does it ask whether you want it to be your default browser? If so, then click OK/Yes to make it your default browser.
If that does not work, go to Control Panel, then to Default Programs, and set Chrome to be the default browser; I believe the screen has an option specifically for email links but I haven't actually confirmed this.
Oh, and I don't know whether you can remove Edge but I suggest leaving Edge alone. As stated above, you just need to get the defaults set right.
