The later releases of Outlook 2016 are certainly supported on TalkTalk Mail on Windows 10 or 11. You'll be able to use the recommended email settings - Incoming mail: mail.talktalk.net - 993 - SSL/TLS Outgoing mail: smtp.talktalk.net - 587 - STARTTLS and outgoing authentication. As you cannot access webmail I'd proceed as though the email account password has been compromised and scan email devices to remove potential virus, trojan or other malware.
A weak password or compromised email account can trigger a password reset or blocking of the mailbox to help secure customer data.
I'll let TalkTalk know that the password recovery options aren't available. A TalkTalk Support member will need to verify you as the registered email user and set up your password recovery alternate email address and mobile number (the Reset details) so you can send a password reset link or code to authenticate a password change.
Prepare for TalkTalk Support - include in the Community Profile (not in these public posts):
Account holder name, TalkTalk home 'phone number (if not Data Only broadband)
Alternative mobile contact number. Full address with postcode (in the Location box)
Scroll down to Private notes to add the email address needing recovery
Check and Save changes
Select here: Update your profile
A TalkTalk Support member will reply to this thread and then Community Private Message you to confirm your customer account details and or details related to the original registration of the email address. Also requested will be the alternate email address and mobile number for password recovery Reset details.
When verified the Reset details will be set up during a working week within 24 hours 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. Check via the TalkTalk Mail sign in that you can access the mailbox.
For a compromised mailbox I'd always suggest scanning your email devices for viruses and malware before changing any password.
Use the new password to access via the TalkTalk Mail sign in check there's no Auto forward or Filter rule diverting your mail messages. Hackers set up or modify Filter rules to spy on your emails.
