Are you a TalkTalk Consumer broadband customer?
Please check the sign in to TalkTalk Mail. Tell us if there's an error message or if you can sign in ok using your known password.
Password Reset details are set up for the email address so that an alternate email and or mobile number can receive a password reset. Please have another look at the Forgotten your Password option.
It'll send a reset to the mailbox itself but that's just for routine password changes. Check there's an alternate shown that you recognise from the hints, and have access to.
Only if you recognise the alternates as yours then please reset the password. Reset code to the mobile 'phone is pretty quick. Make sure the phone is on and in range.
Provided the password has not been reset then if you're a TalkTalk broadband or MailPlus customer and know the current password you can change your email password in MyAccount > My Services > Manage TalkTalk Mail.
Here's the advice article on managing your email in MyAccount.
If the self-help password change / recovery options aren't effective I'll alert the TalkTalk Community team for you.
In the meantime, please update your Community Profile Personal Information (Click here) to include your name, current contact 'phone numbers and address with postcode (location) then scroll down to Private notes and add the email address and Save changes.
If some unwelcome hacker has changed part of the recovery alternatives then they're getting annoyingly clever.
Just try the email address at mailtester.com so I can be sure the mailbox does exist on the server.
If that's good (all green response from the server) then we'll need to get the Reset details checked and updated.
I'll alert the TalkTalk team for you.
Excellent. I've alerted the TalkTalk team to verify you as the registered user, reset your password to secure the account and to set up Reset details.
A TalkTalk Community Team member prefixed with OCE_ will reply to this thread and then Community Personal Message you to verify the registered email user details; so be prepared to provide on request to an OCE_ only:
When verified, the password will be changed and Reset details set up allowing you to set your own password via the Forgotten your Password journey. Make sure the password is ultra-strong and unique to the mailbox.
If you believe the mailbox has been compromised but don't know how this happened then before you change any password take the precautionary approach to scan email devices for viruses and malware that might be capturing passwords.
