Having trouble registering a custom outlook domain

I'm trying to create a custom domain for my outlook.com account. 

One of the moderators on this forum has previously helped me by requesting that my domain be unblocked as a restricted word.

My domain is dminternational.asia

However, I'm now having issues with the mail setup (MX records) part of creating a custom domain.

From what I can see, the custom MX records is set up fine with my server/host and it is the only mx record currently recorded. There are no other mx records recorded.

I have let the changes propagate for over 48 hours and nothing has happened. I then left it another few days and still no change. It just says 'pending changes' 

So I tried switching to a new outlook.com admin account for the custom domain. But still with the same result. 

I really need this custom domain to be fixed because I am losing business while my email is down.

I have previously set up custom domains using outlook.com and had no problems. The only difference is that last time I was using a .com.au domain and this time my domain is .asia

Could this be the problem? Does anyone have the power to look into this?
