Onetel legacy email accounts on TalkTalk secure mail servers Aug 2022- new settings not working

[julianp1]

Hi all, hope someone can help.

I have 3 Onetel legacy email accounts which I've always used for many years with old insecure POP3 settings (Incoming email server "mail.onetel.com" port 110, no SSL), on various Email client apps (Outlook Express v.6 and Outlook 2000 on a desktop - Win XP Pro SP3) and also synced with an Outlook.com email account, plus on a laptop Win 10, using my Outook.com account in MS Mail App.

I have BT broadband, no TalkTalk email or account, and pay nothing to TalkTalk. I also have BT internet, Gmail and Outlook email accounts set up and synced with these email client apps.

However, when TalkTalk deemed to migrate (as notified in emails from August 2022) legacy Onetel email accounts onto TalkTalk secure IMAP/POP3 servers, I was unable to get Onetel email accounts to work on any of the above email client apps in either Win XP or Wind 10 platforms, using either the new TalkTalk IMAP or POP3 secure settings, as per link:-

https://community.talktalk.co.uk/t5/Articles/Email-settings-to-access-TalkTalk-emails/ta-p/2204399

Note: I have and still can access all 3 Onetel accounts on TalkTalk webmail App suite using the Onetel emails and passwords, so that is not the problem.

However, since TalkTalk took the legacy Onetel servers offline on 22nd February 2023, I have been unable to access Onetel emails on any client email app, even in Win 10 Mail app, either with Pop3 or IMAP settings. I have also tried Gondola's suggested Windows Mail on Win 10 settings without success, as per this article:-

https://community.talktalk.co.uk/t5/Email/Correct-e-mail-settings-for-onetel-accounts/td-p/2908320

I get Windows errors 0x800ccc0f, or 0x800ccc92, stating that your user name and password were rejected, or the mail app was unable to connect to the server. 

Not sure if one issue on unsupported Win XP platform with old Outlook/Outlook Express apps, that Internet Settings (Advanced) have only SSL2.0 and 3.0 options, and TLS 1.0 (not TLS 1.1 or 1.2). However, this does not apply on Win 10 laptop with Win Mail, as Win 10 has TLS 1.1 & 1.2 options ticked.

One further complication is that as I'm on BT Broadband connection, and BT require outgoing mail on all client apps to use BT SMTP servers to authenticate outgoing mail, so I've got legacy BT server settings for SMTP (mail.btinternet.com, with BT email account and password, using port 25), and these still work for outgoing mail, even in Win XP platform in Outlook/Outlook Express apps.

I now can't get incoming Onetel email account Inbox messages anywhere except on TalkTalk webmail, whereas I wish to use a mail client app to get all email account messages in a single Inbox.

(BTW. I have made a temporary fix, by  setting message forwarding on all 3 Onetel accounts to my BTinternet email account, so I can still get the messages in one Inbox location, but this is not ideal)

If you saw the message from TalkTalk advising "Our records show that you are still accessing your email using unencrypted email settings, because of this you will no longer be able to receive or send emails via this email app or software" then the email address receiving that notification has been limited to webmail only access as a last resort action by TalkTalk to stop the use of insecure email.

TalkTalk Mail webmail is secure by design using an up to date Internet browser.

Select here:  Sign in to TalkTalk Mail

Enter your full TalkTalk Mail email address and password, select Sign in.

You will be able to get email access restored to email apps or software including mail collection services so long as you're ready to use up to date and secure email settings for all the ways you view emails. We can advise on device and software compatibility and provide customer setup guides. Just let us know each mail collection service, each device, its operating system and email software including version that are in current use.

Do not use any PC that does not support only TLS 1.2 encryption or later. Windows XP / Outlook Express do not support secure mail to the TLS 1.2 standard and any continued use on the TalkTalk Mail platform will get your mailbox permanently locked to webmail only.

Select start button / windows icon
Type Internet Options, Select Internet Options
Select Internet Properties - Advanced Tab
Scroll down
Untick Use SSL 3.0
Untick Use TLS 1.0
Untick Use TLS 1.1
Tick Use TLS 1.2
Tick Use TLS 1.3

Do you know that outlook.com is connecting securely to your TalkTalk mailbox?

For a definitive check of settings take screenshots of the incoming and outgoing server settings, image edit to obscure the first part of the email address and upload here using the Camera icon (desktop browser) or Picture icon (mobile browser) above this reply area.

When you confirm the secure settings are ready I can request TalkTalk Support to restore full access. TalkTalk Support will respond here and access will be restored usually within a couple of working days.
