How can you tell which of your profiles any link you click in an Email will use when Edge starts?

Hi blods 

Great question indeed.

I just tested it.

so I have 3 profiles, 1 personal and 2 work (Office365 business premium)

I have all 3 profiles pinned to the taskbar

and Edge browser canary is my default browser

now here is how the logic works

the links from the outlook email app (and outlook 365 app) are opened in the Edge insider canary profile that I last used.

so if i click on work profile 2 taskbar icon and open the Edge window and then close it, it will be the last profile I used and if i go to outlook app and click on a link, it will be opened in the same work profile 2.

the same happens for other profiles.
