Stuck on “Pending DNS Configuration”

I am attempting to register an email address under my own domain through outlook.com. I have followed a number of troubleshooting posts on here but to no avail.

I have registered the domain with outlook.com (88pixelsdesign.com). I then put the MX Record into my DNS records section of my registrars site (godaddy.com). I copied the information VERBATIM into the fields so there is no way i could have input the information incorrectly. I then waited an hour, refreshed the live domains page, nothing changed. I waited three more hours, refreshed, same result. 

I have used the nslookup function of my command prompt to check that the MX record had updated successfully, as well as two other websites that provide the same service, all of which show that the MX record had been successfully updated. I then came back to the live domains site, refreshed, still nothing.

I'm running low on alternative ideas and patience and would be grateful for any advice anyone can give or anyone who has successfully made this work.

Kind Regards,

Alex
