User Detail > Mail Account Problem

I used to have many accounts and I've just decided to pay. So, I deleted my old account + the domain "bk-property.com" on that it, then put "bk-property.com" on this account " apichris@apichrischotichoey.com" But I'm having a problem that I can't access to the page "Mail Account" in subset of "User Detail". It said " Operation not permitted" in red box.

As I can see, Zoho system migrated my old account settings and block my access to change "bk-property.com" settings.

Please unblock it,

Thanks,

Chris
