Linked incorrect email address with Office 365

Linked incorrect email address with Office 365

Hello All,
I am in the process of enabling Zoho CRM to work within Office 365.  I went to the Office 365 app store, and found Zoho CRM for O365, I click get it now, and I associated my Zoho account with a brand new trial version of zoho when I meant to link it with my already existing account.  How do I associate my O365 with my already existing Zoho account when Zoho has my O365 email associated with a brand new trial account?

Thank you,
Dave
