I've logged onto the new Mailbox Manager at https://apps.talktalk.co.uk/myaccount/ and I've been able to delete two ancient tinyworld.co.uk email addresses. However, I have one remaining email address with you (talktalk.net) and the Manager doesn't allow me to either delete the address [error is "RequestError: 400 ERROR_LAST_ADMIN_REMAINING (The last active admin cannot have their status removed - JSONException)"] or deactivate it [error is "RequestError: 400 ERROR_LAST_ACTIVE_REMAINING (The last active admin user cannot be deactivated - JSONException)"].
It looks like the Mailbox Manager expects there always to be at least one active email address on the account but surely it should allow all addresses to be deleted. One problem might be that the email address used to log in to the Mailbox Manager is the talktalk.net address that I'm trying to delete!
