It looks like I somehow linked my Zoho email and yahoo email (don't exactly remember doing this), but I can't unlink the accounts. In the Zoho email settings it shows "no accounts linked", but my Zoho inbox is still flooded with email from my yahoo account. Additionally, when I sign in to Zoho and the page is loading, it's showing my yahoo email.

How do I get these unlinked? The yahoo account gets nothing but pure spam and it's junking up my Zoho inbox.
