How can I delete the configurations in any prior organisations to integrate your IMAP account with the current organisation?

Note:

You have already integrated your IMAP account with Zoho CRM in your previous organisation. We are currently allowing IMAP integrations with a single organisation. Kindly delete the configurations in any prior organisations to integrate your IMAP account with the current organisation.
