Zoho CRM POP Mail account multiple emails

Zoho CRM POP Mail account multiple emails

Hello. I have added one pop email account into the crm using the zoho mail app add-on, and currently it's synced all past emails to each contact.

We have another email address that I was hoping to also sync with the crm contacts as well so I added it as a second pop email address, but still under the same zoho crm user account. 

It doesn't seem to be pulling this second pop account's emails into each contact... is there a way to do so?

Thanks,
