Have a Virgin mobile account which receives NTL mail. Can I also get my NTL mail in Outlook on my Windows 10 laptop using my mobile account passwords etc?
Yes you can, though you'll need to set up your accounts as IMAP rather than POP, so that the emails remain on the server and are therefore accessible by all mail clients/apps.
The below links will provide the information you require to set this up:

IMAP OR POP (microsoft support)
