Using classic Outlook for Windows in business environments
Hello,
Once a hotmail or outlook alias is deleted from a Microsoft account as an alias, that account is gone permanently. Microsoft doesn't reuse its own email address, so it cannot be added to created as alias for another Microsoft account.
Microsoft explains it here: https://support.microsoft.com/office/add-or-rem...
Under the section "Remove an email address", it says:
"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 am very sorry. I wish I could share better news.. but it is important that I stay honest and don't mislead you.
