Hi @lyntramp
This exact issue happened to me, yesterday evening, impacting classic TalkTalk Webmail whilst email collected using email clients or email apps and email via the new TalkTalk Mail platform was unaffected.
The workaround worth trying is to collect your emails via an email client like Outlook or Thunderbird, for example, or an email app on your mobile 'phone or tablet.
If you need them, the email client / email app settings are in this TalkTalk article.
In the meantime I'll alert the TalkTalk Community Team for you. Please ensure your Community Profile Personal Information (Click here) includes your name, address, current TalkTalk landline 'phone number and an alternate number (mobile recommended). Add, then scroll down and add the email address in Private notes and save changes. The TalkTalk Community Team OCE will then be able to link to your TalkTalk service account and the email account and check it out.
