Cant recieve mail

outlook.com said that you can import other email addresses you have and add them onto your live email, well I added another address so I could check emails from just logging onto outlook(Hotmail), but when I click on the other email address I added to see if I have any emails from that address I get nothing, and I cant even send emails with the other email address that I did add, only the outlook email(Hotmail) works, how do I get the other email address I added to outlook(Hotmail) to work? my usual email address is a **********@Hotmail.com, the other email I added so I can check my emails is a *****@rogers.com. I want to be able to check the ROGERS emails on my HOTMAIL address, but nothing comes from the ROGERS email to say I have email from it. I have to be on my own computer at home to check the ROGERS email, which will then show I have mail, I want the ROGERS emails to show in my HOTMAIL when I'm using different computer, so I can check emails in one place. Anyone know how I can do this, please?
