Problems with using email in Outlook - logins rejected

[Flaneuse]

I have two email addresses xxxx@talktalk.net. I can access them both on Webmail to send and receive. Using Outlook, I can as of today access only one. The other will neither send nor receive. I have changed nothing in the Outlook account settings for either. The one that doesn't work uses incoming server mail.talktalk.net, outgoing smtp.talktalk.net. The one that does work uses incoming server pop.talktalk.net, outgoing smtp.talktalk.net.  The address that doesn't work is the main one I  use to login to TalkTalk.

It's magic? Let us know if you need anything else.

It's now working. Nothing changed my end re passwords or settings. Receiving came back before sending.

Hi Flaneuse 

There was an outage of the sign in authentication between 0800 and 0919. If you made any changes during that time then Outlook may be using an incorrect password. 

You've not commented on the password strength? If the password is deemed weak then when the authentication system came back online it might be rejecting the password.

Why not just upgrade the password? That would be what I'd do right now.

Both email addresses are listed as active. Has something has changed today with regard to password authentication or anything else, because it worked before? I access my TalkTalk customer account using the email address and password that does not work for Outlook; it is the primary one on the account.

Hi Flaneuse 

Are both email addresses listed in an active customer MyAccount? And is the password, for the non-working mailbox, strong enough? A weak password may get you signed in to webmail but fail authentication by the mail servers.

The Reset your password now button in the help article  Changing your email password will take you to password reset and recovery. 

If the email address is still active on the TalkTalk Mail platform and you have set up password recovery options, in advance, that you recognise from the *****hints, then you can send your alternate email address a link or your mobile a 6-digit code to authorise a password reset.

Just to confirm that the Outlook server setup for all TalkTalk mailboxes is the same. The incoming server host name is recommended as mail.talktalk.net but pop.talktalk.net is also listed on the server certificate and will access the same server.

On updating the email software incoming, outgoing and some advanced server settings, you'll possibly be asked to accept a new certificate (yes, accept) and to enter the email password so have the current password ready. Tick to remember or save the password before entering it.

Supported^* email client and app settings are:

Account Type	IMAP (recommended) or POP3
Username	Full email address
Password	Email password
Incoming mail server	mail.talktalk.net
Incoming Port (IMAP / POP3)	993 / 995
Incoming Connection Security	SSL/TLS
Outgoing mail server	smtp.talktalk.net
Outgoing Port	587
Outgoing Connection Security	STARTTLS
Outgoing Authentication Required	Yes
Authentication Method	Normal Password (NOT SPA)

It's also important to make sure the email address is added to a TalkTalk Consumer customer MyAccount to avoid restriction to webmail only access and possible deletion.
