There’s a problem with this website’s security certificate

[softwareguru]

"There’s a problem with this website’s security certificate" is the message I get when opening Microsoft's "Live Mail" using Outlook.

I can ignore it and open mail, but find no reason for warning.

Make sure that your system time, including timezone, is set properly.
