Sorry for the delayed reply and to unfortunately advise that once deleted from myaccount there is no way to recover the mailbox, this is why we have the "are you sure" message before the mailbox is removed to help mitigate any accidental deletions.

Please log in to My Account if you need to view or pay your bill, manage boosts and track your usage. From My Account you can also check your connection and test your line for any issues in the Service Centre.
You're confirming that you can sign in to the mailbox via an Internet browser and the TalkTalk Mail sign in here and you can see the Inbox and compose and send the same mailbox address a message and that message appears in the Inbox. Yes?
You're also saying that you have subscribed to TalkTalk Mail Plus because you're not a current TalkTalk consumer broadband customer. Yes?
When you subscribed to MailPlus you'll have received an email confirmation giving you the MailPlus MyAccount number and the Direct Debit details.
Have you signed in to the MyAccount to make sure the email address is already listed in the My Mailboxes? The reason for asking is to make sure the subscription went though ok and if the mailbox is listed then setting up an email account again using an email client or app should be a problem.
You say you can access the mail messages via webmail. So, that at least is going to keep you in contact.
But, if you cannot access mail messages via an email app that implies either the app isn't working / set up correctly or the mailboxes are restricted to webmail access only.
The mailboxes are listed in your MyAccount. If that's the new Mailplus MyAccount then the mailboxes will not be restricted.
Are you signing in to the new MailPlus MyAccount or your former broadband customer MyAccount? If it's the former broadband customer MyAccount then there's likely to be a yellow banner message below the My Mailboxes that indicates you do not have an active subscription.
Let us know.
