If you are a customer using the 3rd party email service or a Microsoft Account user who is unable to receive emails from a particular 3rd party domain:

 

Contact your domain administrator and ask them to get in touch with the Microsoft Sender Support Team. They have to fill out the e-form that can be found on the following link:

If you do not know how you can get in touch with your domain admin, you can use WHOIS tools to search for your contact e-mail address of your domain admin.

 

If you are the 3rd party Domain Administrator:

 

Please review our policies and guidelines at http://postmaster.live.com.

If you are in compliance, submit a support request to our Email and Delivery Filtering Services team by clicking on the link to the e-form under the troubleshooting section in the postmaster site mentioned above.
