Why is Outlook telling me "There’s a problem with this website’s security certificate"

[Windows Central Question]

Here's what happens when I click on OUTLOOK from my homepage:

 There’s a problem with this website’s security certificate
This might mean that someone’s trying to fool you or steal any info you send to the server. You should close this site immediately.

 Go to my homepage instead


 Continue to this webpage (not recommended)

What's up with this?

Is this when you try to sign in directly to your Outlook.com email account? If so, same happened to me using Edge. It may be MS changed something. Log in through, and point any browser bookmarks to http://www.outlook.com/owa and it won't show that message.
