You cannot delete an email address that is [marked as primary](https://www.zoho.com/books/help/settings/emails.html#mark-primary). If you use any/all of the following **Zoho Finance** applications, go to each app and check the Sender Email preferences. * Zoho Subscriptions * Zoho Expense * Zoho Inventory * Zoho Checkout If the email address you are trying to delete is marked as the **primary** email in any of them, you will be prohibited from deleting the email address in Zoho Books. Instead, you can mark an alternate email address as primary in all of the apps and then try deleting. * * *
