My server settings for my original POP3 account has changed, for some reason I cannot edit or even delete this account.  I have even added another POP3 account and set it to the default in order to try and delete the old account but nothing works.

The implication of this is that I cannot setup an IMAP or POP3 account in ZOHO CRM with the original email address as an error pops up saying that there is already an email account in ZOHO mail with the same email address.

So my question is how do I delete this old account in ZOHO mail (there is no delete button..)?
