Message Center. Whenever you see this, do NOT click or open it. This is a scam designed to get your personal information. In this case, it is very easily recognizable. The return address is something like email@example.com. That certainly does not look like anything Microsoft or any other email provider would send. The content of the email will say:
[Verify email address]

I broke the link but first gathered the information. This is where the link would have taken you. joberspot.in.net.G5.***. You do not want to click on any suspicious links.
These scams are running constantly. If you cannot see the return address, hover over it. It will show you where it is coming from. Be very careful out there!
