How are you accessing email on your laptop & what domain is this on (e.g. talktalk.net). How do you access them on your phone? To see them on both & in sync, you would need to use the IMAP protocol, not POP3.
The TalkTalk Community has now moved to a peer-to-peer support model. This means that the TalkTalk team will no longer be here to support with queries. Don’t worry, there are plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here
