So I started getting all of my links in emails replaced with *.safelinks.protection.outlook.com.
Logged into the web portal to check out what was going on after I did some googling and found it was and Office 365 protection feature.
While about to goto options I saw there was a premium option in the menu.
Clicked it to see where it went and got the following.
Your Office 365 subscription comes with premium Outlook.com features.
You now have an ad-free inbox with 50 GB of storage and enhanced security.
Thought it was interesting as it used to be extra and I was kind of umming and ahhhing as I really only use the browser based email at work.
