now i am getting a different message.
Can't verify domain.
sintexinternational.com has already been verified for your account, or for another Microsoft Office 365 account.
My guess this is due to that i ahve verified it with a previous trial, but i have no way of getting back into that account. The rep ask me to open a new Trial.
I have also deleted all the DNS on yahoo, but still have this problem. please help.
