Hi,
1. How many aliases can we've with our already existing Microsoft account? According to the page:
https://account.live.com/AddAssocId?ru=&cru=&fl=

Your account can have up to 0 aliases, each of which lets you sign in to all the devices and services that use Microsoft account. Your aliases share a single password, and you can send and receive mail with each.

2. When hotmail has been merged with *** Email address is removed for privacy ***, why can't I send or receive mail with

*** Email address is removed for privacy ***

Kindly guide.
