I actually use opera as my default browser but when i get an email like pic 1 ( has the Blue I circled) and I click on open in browser it defaults to edge and shows the picture in the next post. I separated the pics as they looked like one picture .

lot's of google info but very confusing. You are supposed to be able to use an Internet exploder mode in Edge but it then says it can't find the program and to reload IE. very frustrating.
As previously mentioned lot's google info but very hard to follow Typical MS 💩
