can't use my corporate email address with zohomail add on in CRM

can't use my corporate email address with zohomail add on in CRM

I have zohomail add on enabled in my ZohoCRM so when I get emails sent to my corporate Exchange email address I forward them to zohomail and then I can view incoming emails on their records in ZohoCRM.  The problem is I can't SEND contacts emails from ZohoCRM with my corporate email address when I have zohomail enabled, it forces me to send the mail from my Zoho email address.  The only way I can send emails from my corporate email address in ZohoCRM is to disable Zohomail and then I can no longer view incoming emails!

This is so frustrating, I can either choose to view incoming emails and not be able to send emails with my corporate address, or I can choose to send emails with my corporate address and not be able to view incoming emails.  There has to be a way for users with an Exchange (not pop) corporate email account to both receive emails and send them.
