I assume you are using Outlook still?
Is this happening in webmail?
If not then this can sometimes be solved by deleting your account from Outlook or Thunderbird or other 3rd party program, and closing the application, then reopening and adding the account again
If that doesn't work, then you will need to phone or chat for support as there are no support staff here any longer.
However, I doubt they can help if it's not a webmail issue and you may have to seek advice on a forum dedicated to your email client.
If you wish to contact support staff then contact details can be found by following the link in my signature below.
Hope though my advice helps you.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
