I can log in to my live account and I can send emails. However, I can not receive emails.

The problems started when I got a new ultrabook and started playing with Windows 8 apps, aliases, features etc.

I received this email:

"Start using your new address
Now you have a new address, *NEW ADDRESS*, make sure your friends know.
Here are some things to consider:

     The email sent to your old address will continue to reach your account.
     Remember to always login with your new address, you can not log in with the previous one.
     If you want to stop receiving mail sent to your old address, just delete the address in account services.

Thank you for using Outlook!

I have no idea what this email means. The new address that is listed is actually my school/work email address that I have had for a couple years now.
Not sure what is going on there? I was playing with the aliases options when this email was sent, however. This school/work address is technically a gmail account.

Moreover, I received this notification a day or two ago when I was on my live account:

"Your messages are in your POP folder! Some other program is set to download and delete your messages from Outlook. Just in case this was an accident, we've put them in a special POP folder. Not an accident? Change settings."

Okay, but there are no messages in my POP folder.

I use my live account for absolutely everything. Is there anyway that it can be fixed so that it operates like it used to?! Where I can just send/receive emails!?

Thank you!
