The weird looking email address is your "base" Outlook email account Id. To add a readable alias:

If you are using New Outlook Web version. i.e. You open your browser to https://outlook.live.com/

You can only have one email account and which account that will be is determined by how you logged on. If you want to change accounts, then Sign Out (click on your profile avatar in the upper right) and close your browser. When you go back to https://outlook.live.com/ it will ask you which account you want to use.
