Safari website warning

Yes, it seems it was a url opened from the Outlook App.

Its an actual warning from Safari, and most browsers will issue it as well.

Tried it on my iPhone and get the same red warning. You can close the tab and forget about it.

Actually this time It's a genuine warning. The site is classified as a deceptive website.

I get the same warning on a computer for it.

Why do you need to visit that website?

Any such message will be a scam.
