Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do what I can to provide the right answer to your question.
Please tell me what email system or other system 'Orange' is... I confess I don't recognize it offhand. (AOL of course, I know well enough for sure.) And I understand your question otherwise - what you will need to start with, is to check that you can still log on to your AOL email account, and access your Personal stuff in general. That's a start.
After that, generally you either Export the personal stuff, File Cabinet or whatever it is called in your version of AOL... and then you would do an import to whatever 'Orange' is, speaking in very general terms. If you tell me what 'orange' is, I will instruct you in more detail.
Did AOL send you a notice of termination ?
Why do you think you no longer have an AOL email address and account ? were you perhaps sending excessive quantities of emails per day ?
