Review Microsoft's Alias Recovery Policies
Understand Microsoft's strict rules regarding deleted aliases to determine if your specific email address can be recreated.
Microsoft maintains strict security policies regarding email aliases. If you remove an alias that is an email address from a Microsoft domain (such as @hotmail.com, @live.com, @outlook.com, or @msn.com), it is permanently deleted and cannot be added again to any Microsoft account.
However, if the alias was a third-party email address (like Gmail or Yahoo), it can typically be re-added as long as you still own the address.
Log in to your Microsoft account and navigate to the 'Your info' tab, then select 'Edit account info'.
Click on 'Add email' and try typing the removed email address. If it was a Microsoft domain, the system will likely notify you that the address is taken or unavailable.
Visit the official Microsoft Support page for adding or removing an Outlook.com alias to read the complete policy on domain restrictions.
Retrieve Emails via POP Server Storage
If you used a POP connection to download emails, the messages might still be preserved locally even if the alias is gone.

Frequently Asked Questions
Can I reuse a deleted Outlook.com email address?
No. If you remove an alias that uses a Microsoft domain (such as @outlook.com, @hotmail.com, or @live.com), the email address is permanently deleted and cannot be tied to any Microsoft account again.
Did I lose all emails when I deleted my alias?
Not necessarily. Since all aliases on a Microsoft account share the exact same mailbox, the emails sent to the deleted alias should still be in your primary account's inbox unless you manually deleted them.
Can I restore a deleted alias from a non-Microsoft domain?
Yes. If you remove an alias from a third-party domain (like @gmail.com or @yahoo.com), you can add it back to your Microsoft account, provided you still have access to that third-party email to verify it.
Why does Microsoft prevent recreating deleted aliases?
Microsoft permanently deletes removed domain aliases to protect user privacy and prevent security issues. This ensures that someone else cannot register your old email address and intercept your private communications, password resets, or personal data.
