Managing personal Outlook.com account settings, security, and privacy
@Greg Jones said
its just an email for verifacation purposes, each accouint requires you to have a different email address
I'm not sure what program you are signing up for, but if the requirement is to just have a different email address (and not a different outlook.com account) for each registration, then you might be able to just create multiple "aliases" all under one account?
You can create a new outlook.com email alias at https://account.live.com/AddAssocId
And you can see all of the aliases connected to an account at https://account.live.com/names/manage
If I'm totally missing the point of what you are trying to accomplish, please provide some more details on the program you are trying to register for.
