I need password reset option enabled for my custom domain accounts on the Windows Live Admin center

I use the option "join accounts" in Outlook. This morning this option deactivated, without letting me know when this would happen. The big problem is that I can't reset the password despite all the information provided to Microsoft. (I can say I'm really angry!)

I see just one other solution, I use live domains can you please activate the option: reset password.

My domain is: gatto-rosso.nl
