If you're a TalkTalk Consumer broadband customer and all your TalkTalk managed mailboxes are already added to your MyAccount My Mailboxes list then you need do no more.
So long as you see the mailboxes listed and you have no more to add and there's no yellow banner error message, all is good. In fact I'm surprised you got an email from TalkTalk.
I'll get you added to the list for a fix. Your mailboxes are, I suspect, associated with a former MyAccount so they're appearing with the attributes of that disconnected account.
TalkTalk will need to move your mailboxes to your current MyAccount and remove that error message that's preventing you from adding more orphaned mailboxes or creating new ones.

The request for TalkTalk attention was made days ago. I'm only too aware that we haven't had the regular TalkTalk support for email and webmail for over 3 weeks now.
The UK support team that we can normally rely on for support during weekday office hours has been redeployed to help vulnerable and key workers remain connected to broadband and phone services. That team is now working 7 days a week from early morning to late evening.
I have no visibility of TalkTalk team workflow, timescales or present priorities but I have asked for some help here and help has started to arrive.
I can see that you have four email addresses list in my-account, the email you received asking to sign up to mail plus was that sent to one of these four? If you could reply to the private message im sending now with the email address you originally posted about i'll make sure it's added if not already.
If it is already listed then this email was sent in error and you can disregard.
