Configuring preferences and options in Outlook.com
Hi there! My name is Brandon. I'm an Independent Advisor and a Microsoft user like you.
I understand how important it is for you to access your email account.
If you removed your email account from the list of your alias, I'm, afraid that you can no longer recover it.
Deletion of addresses or accounts is effective immediately. And this is permanent.
You can check this support article:

There is an important note from the link above:
* Are you sure? If you remove an alias that's an email address from a Microsoft domain (like @hotmail.com, @live.com, @outlook.com, or @msn.com), you're permanently deleting the alias and it can't be associated with any Microsoft account again.
I hate to be the bearer of bad news. This is the policy that Microsoft follows.
Hope that I was able to address your concern. Have a great day.
