NOTE: I had to categorize this post as a "Windows Live Mail / Sign-up" problem, because there was no category for Windows Live Domain Registration.

I am trying to register my domain for Windows Live under "domains.live.com". To do this, I need to prove ownership of this domain by creating a DNS record, which I have done. The MX record is successfully saved on the host server with all the details as required. However, when I click on the refresh button under "Manage Domains" it continues to insist that I need to provide proof of ownership (by creating the MX record...which is already done).

No matter how many times I repeat this process I can't get Windows Live to check that the MX record is there. I have also verified that the MX record is set up correctly several times, and I am convinced that it is, so this is not the problem -- For some reason, Windows Live is just not able to verify the MX records on the host server properly.

Can anyone help?
