Sending, receiving, and organizing email in Outlook.com
Hello Alois
Thank you for reaching out to the Microsoft Q&A Forum. I understand how stressful it is when an old email alias disappears and ends up blocking access to another account.
Unfortunately, there’s no way to view the history of old email aliases (addresses you previously added or removed). Microsoft does not store a visible record of deleted aliases, and once an alias is removed, it will no longer appear anywhere in your account. Make sure that you already tried Q&A Assist suggestions. Also, please review all current aliases, sometimes an alias is still present but displayed differently. You can refer to this article to check your alias list: Add or remove an email alias in Outlook.com - Microsoft Support
Also, please carefully recheck your old emails. When reviewing older conversations from years ago, even though the visible “To:” address is rewritten, you may still find helpful clues such as:
- Username patterns
- Subject lines referencing the old address
- Registration confirmations from the social platform showing the first letter or partial email
- Old password‑reset emails
If you’re unable to retrieve the information yourself, please try contacting Microsoft Support:
- Go to Contact - Microsoft Support
- Type a brief description of your issue in the search box.
- Click "Get Help", then scroll to the bottom and select "Contact Support”.
- Choose the appropriate Product and Category
- Look for and select "Chat with a support agent in your web browser" (during business hours) or a similar callback option (if available). Explain your situation clearly.
If the social media service has no support contact and the only recovery method is the lost email, your only option may be to reconstruct or re-register that old address if possible. If it was a non‑Microsoft email (Gmail, Yahoo, ISP mail), you'll need to attempt recovery through that provider.
Thank you so much for your understanding.
