To unblock your email account that has been flagged as spam, you can use the delist portal to request removal from the blocked senders list. Here are the steps you can follow:
- If you received a Non-Delivery Report (NDR) indicating that your email was blocked, forward that message to
delist@microsoft.com. Include the full NDR code and your IP address. - Microsoft will contact you within 48 hours with the next steps regarding your request.
- For more information, you can refer to the delisting form for Outlook.com and ensure you read the FAQ for submission directions.
If you are using Microsoft Defender, you can also check the Restricted entities page in the Microsoft Defender portal to identify and unblock your user account directly.
