Can't get new email account verified to allow me to set up on new PC

I've not used VirginMail for some time as I had it all set up through Outlook on my old PC. This has now died, so I'm having to use VirginMail, but I'm getting an error saying 'The entered credential or authentication information does not work or are no longer accepted by provider. Please change them.' My problem is that I'm not sure what has changed or is wrong.

Thanks

Hi nomisluapc, 

Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐

We're sorry to hear the email is arriving after it's expired. Depending on your non-VM email address settings, it may be delaying the verification email. There isn't a way to bypass this however we could try forcing the verification email through. 

In order to do that I will need to confirm some information with you to pass security so I have sent you a direct message to allow us to do this with you in a private space. If you are using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you are on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊

Thanks, 

I thought I'd already posted this, but can't find it so am doing so again.

I've not used Virginmail for some time as I've set up email through Outlook. However, my PC has died and I've got a new one so I'm back with VM. However, when I go to accounts I get a message saying 'The entered credential or authentication information does not work or are no longer accepted by provider. Please change them.' for the linked email accounts. As far as I'm aware I've not changed anything, and I'm not sure what I need to edit.

This may be linked to a secondary issue I'm having with adding a non-Virgin email account so I can get myself set up with Outlook again.

Any help gratefully received.

Thanks, and apologies if this does turn up as duplicate post.
