Start using your new alias: Here are a few tips to help you get started: ??

Hello, Microsoft Community ........ I am new to Outlook.com and have just set up several alias addresses.  In the body of each of these addresses it says in order to start using the alias address,

     "•To send email messages from this alias, click on your address (above the To line in the message) and select your alias from the list." 

Multiple times, I have clicked on this 'n that above the "To line in the message" and nothing works!  There is no list there, and appears to be no access for one to begin with.  In fact, even with found buttons and pull downs, I am discovering many of them are not responding to being clicked on -- but that is another topic, another discussion.  

How do I activate my alias addresses so that I can begin sending 'n receiving emails with each of them?

How can I have these several new email aliases listed on the left side of the screen, and with their own Inboxes, and so on?

In addition, how do I, also, add the Outlook.com email addresses to my Office 2013 Outlook (Windows 7) email accounts?  

I would need the incoming/outgoing mail server information, and the incoming server (POP3) number, along with the outgoing server (smtp) number -- and, does the outgoing server require authentication, or not ??

Thank you for your consideration to my inquiries.
