I have an up-to-date Mac and browse the net on Chrome. My email is a Gmail account but I also have an Outlook account for "junk" emails which I've had for around a year. But Outlook.com almost never opens - and never has. I get the Outlook logo and the "opening your mailbox" for about a minute and then it says "This site cannot be opened. outlook.live.com's server DNS cannot be found." So I reload. And reload. And reload. And after many many attempts (often about a dozen) it opens. Am I really the only person with this problem?
