I am in the middle of pointing my MX records over to outlook.com for use with my custom domain. I submitted the MX record change at about 9am this morning. Now, at a little after 3pm, I am able to send and receive mail at Outlook.com using my original email address... however, I am still unable to "Prove Domain Ownership" - which means I can't finish the email setup, etc. Is this typical? Is there just more waiting that has to happen before I can prove ownership? I have submitted both an MX record and a TXT record. Not sure what other steps can be taken at this point.

Can anyone help?

Thanks.
