You'll have to code this app' in C#.
This program will have to connect to an Hotmail Account (with an authentic user-agent like chrome), then go to this email's inbox, then open a mail, and click on a link contained in this email., simple as that, you can use external library.
We don't have to see what is going on, we just want a confirm message, that says "Done" on a Windows Form, when the link has been clicked.
Thank you for reading this project's description.
PS: People who can do it quickly, will be favored..
