Hi, my email ntlworld.com will be closing soon

Hi

i I have an old ntlworld.com email address

I have moved house to an are where virgin do not supply so they told me my account will close in 90 days

i have opened an outlook account and made all the changes where necessary 

however I have lots of emails ie from the solicitor etc that I wish to keep

if I forward emails sent to my ntlworld email to my outlook email, when I open the email will I still be able to see the emails and contents and attachments of an ntlworld email once they close my ntlworld email account 

thanks
