Zoho mail-account not active

Zoho mail-account not active

It seems i have to ask this separately. I have registered a valid hotmail address as my login email address and received verification link and clicked through to Zoho verification page. Still, when i clicked "Access Zoho mail" afterwards it showed "Account not Active".  

I have used the hotmail address for many years. 

Could you please advise how shall i proceed?  What kind of email can we use then other than hotmail?

Thanks in advance!
