Troubleshooting:

You cannot delete a primary email address ( denotes primary email address) straight away. You have to add another email address first and set it as the primary address, after which you can delete the required email address.

1. Email address hosted using Zoho's domain, (i.e., an @zoho or @zohomail address) cannot be deleted, as it is mapped to the Zoho mailbox. As long as the account is active, the email address cannot be deleted.

1. If you have hosted your custom domain on Zoho Mail and created a custom email address using it, you cannot delete that email address from the Zoho Accounts page. You need to go to your Zoho Mail's Admin console,
   

To delete an email address,

1. You need to have another email address for it as alias.
   
2. The email address you want to delete should not be a primary or a login email address.
   
3. If you're an organization user, you need to contact your administrator to delete your email address as Admin console will not be available for you.

1. Go to Zoho Mail.
2. On the top-right corner, click the profile icon.
   
3. Click Admin Console.
4. Click Users on the left panel. (You'll find list of all the users added in your account).
   
5. Open the one you want to delete.
   
6. Go to Mailbox Settings.
7. Click +Add to add an alias email address. (skip this if you already have one)
   
8. Go to Security, click Login Email Address, then set the new email address as primary.
   
9. Go back to Mailbox Settings, then press () icon next to the email address you wanted to delete.
   
10. Enter password to verify and the email address will be deleted.
