I'm trying to set up a custom domain for Windows Live Admin and I'm getting the following error:

You need to prove ownership of this domain by creating a DNS record. Use the settings below.
You can Cancel service or Edit mail settings

The issue is, I have already added the DNS record provided. Doing an MX lookup provides the following information:

nslookup > set type=mx > blah.com

blah.com     MX preference = 1, mail exchanger = 1ba5ed018f3d4ea6d1d3709c4c9a31.pamx1.hotmail.com
blah.com     MX preference = 5, mail exchanger = ALT1.ASPMX.L.GOOGLE.com
blah.com     MX preference = 3, mail exchanger = ASPMX.L.GOOGLE.com

Since there is a higher priority on the Hotmail server, this shouldn't be an issue. Is Windows Live Admin Center failing to detect its MX record because it sees Google? I would prefer not to have downtime with my e-mail account while it switches over.

PS: I can access calendar and send e-mails through Outlook.com, but I don't receive them.
