Hello K AM
Thank you for reaching out to the Microsoft Q&A Forum. I understand that when you try to sign in, an unknown email address appears during identity verification, causing a verification loop that prevents you from accessing your Microsoft account.
Please kindly note that this is a public user‑to‑user forum, and I do not have the tools or authorization to unblock accounts, recover accounts, or bypass security measures. Only Microsoft’s official recovery process can restore access.
To proceed, please try using the Account Recovery Form (ACSR) via https://account.live.com/acsr
When completing the form, make sure to:
- Use an email address you currently have access to as the contact email
- 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
Contact Support Team directly
If you are unable to complete the Account Recovery Form or are experiencing issues with it, please reach out directly to the Microsoft Support team. 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 (e.g., I can't sign in)
- Click "Get Help", then scroll to the bottom and select "Contact Support”.
- When prompted to select Products & Services and Category, choose the appropriate categories.
- 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.

Thank you for your understanding. I hope you’re able to regain access soon. If you have any further questions, feel free to reach out.
