> In other words, it injects spam, but the spam is special because you can't delete it. During this week, I had a client approached me to build him a Spam Reporter Outlook add-in. He wanted the add-in to be cross-platform (Windows, macOS and Web). I started working on the project by creating a new project in Visual Studio 2022 and choosing Outlook Web Add-in as a template. Once the new project was created and ready, I pressed F5 to run the boilerplate, "Outlook.com" was launched in the browser (Edge) and it took forever to load! The loading spinner keeps turning.. then I realized, there was an error in the code and the execution was held until I choose 'Step Forward'. I was really puzzled why a fresh project could crash in the first attempt, then I quickly noticed the error was not in the project's code but in another .js file that was loading in Outook.com tab, checked the js URL just to find the domain it belongs to is unusual (at least for me),it reads something like "https://www.taboola.com/loader.js https://www.taboola.com/loader.js". To add insult to injury, this file was reloaded every time I clicked on a different email, it drove me crazy when I realized this "loader.js" was actually an ad injector, there was plenty of spammy ads on the right side of each email opened. Somehow, I was able to block this whole garbage by simply accessing the "Network" tab, find this .js devil then blocked it. Only then, I could continue to work on this project peacefully!
