Not receiving emails in Outlook for Mac 2011. Sending okay.

Not receiving emails in Outlook for Mac 2011. Sending is okay so am connected to the web. Using outlook.com for web mail service.

What is the current correct name for the incoming server on outlook.com? Surfing the web comes up with

pop3.live.com (original setting)

pop3.outlook.com

pop-mail.outlook.com (microsoft setting on the net and what is currently setting on my machine)

pop.outlook.com (recommended setting in outlook for mac help section)

Tried all of them and still no luck.

Also how long do I have to wait to hit send/receive before I can hit again? Isn't there a 15 minute interval?

Thanks
