I asked for help on Microsoft Community but did not get a reply so I hope someone here knows what's going on. Anyway, I have created a new Hotmail account yesterday. Right away, I tried adding my newly created Hotmail account on Sparrow for Mac. But I kept having issues, for some reason it says that the login is incorrect (see screenshot). I have entered the correct email and password. I tried several times. I thought it was an issue with Sparrow but I tried adding my old Hotmail account and it worked fine, so it's not the app. So I then tried adding my new account on the stock Email app on my Samsung phone to check, it worked and I can send and receive emails. This morning, I got a Facebook message (via Email app on phone) with the subject "Jay, you have 4 messages" (screenshot below). My name is not Jay Lee and I did not sign up on Facebook with my new email and this got me thinking, could it be that someone else is using the same email address as me?? Is this possible? Is this someone also receiving my emails?
