Thank you for reaching out to Microsoft Q&A Forum. I understand that you want to remove two unused Outlook email addresses while keeping your original Microsoft account, but you are unable to do so because you do not have the passwords and cannot find a delete option without closing the entire account.
Please make sure you already tried the Q&A Assist steps. In addition, here are some steps that you could try:
1, Sign in to the Microsoft account that you want to keep using.
2, Go to https://account.live.com/names/manage and review whether the unused Outlook addresses appear under Account aliases. If they appear as aliases, remove them one by one. If one is marked as primary, set a different alias as primary before removing it.
3, If the unused Outlook addresses do not appear as aliases, they are separate Microsoft accounts. For separate accounts that you cannot sign in to, they cannot be deleted or modified without successful authentication.
4, Check whether any recovery options are still accessible, such as alternate email addresses or phone numbers previously added to those accounts. If there are no recovery options, please fill out recovery from (ACSR):
- Go to: https://account.live.com/acsr
- Enter your original email and an alternate email where Microsoft can contact you.
- Provide as many accurate details as possible, such as old passwords, frequent contacts/subject lines and submit from a familiar device/location.
- Wait 24–72 hours for a response. You may refine and resubmit up to twice per day.
- Please see this official guide to help you fill out the form more accurately: Help with the Microsoft account recovery form - Microsoft Support
If you are facing any issue in recovery progress, you need to contact Microsoft Support directly for further assistance. It may offer live chat and, depending on your subscription/region, an option to request a callback:
- 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 Products & Services/ 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.
Please kindly note that this is a public user-to-user forum, I do not have the ability, tools to unblock, recover accounts or bypass security. Only Microsoft’s official recovery process can restore access.
Please feel free to let me know how it goes. I truly appreciate your time and understanding.
