Hi, I'm Karl and will be happy to help you today.
Rules surrounding Microsoft based accounts
#1 - Once an account is permanently deleted, it can never be recovered / recreated
#2 - The action of removing a Microsoft based alias email address is both immediate and permanent. It can never be recreated or recovered, This is described at the bottom of the following article
<"I want to move or transfer my alias to another account to merge or consolidate accounts">
Change the email address or phone number for your Microsoft account

#3 - You cannot add an existing Microsoft based email address as an alias to another existing account
#4 - You cannot add a deleted email address as an alias account
#5 - If you try to create a new account using a deleted email address, you would encounter an error message that the email address is already in use. That is technically correct since every email address is maintained in a database so that it can be checked. What is misleading about that message is that it does not indicate that it involves a deleted email address which causes confusion
