Troubles with configurating Mails after domain verification and MX records configuration

Hi,

I have tried to contact by phone several times this morning with no answer.
This morning we had verified our domain and configured the MX records correctly. The problem began when configurating the old mail accounts we were no able to asign a domain based mail account as the defaut accont of the users (instead the @zoho.com mails)

Please we need somebody to contact us very badly. We are having serius issues with the emails.

Regards
