Is there a way to keep all my e-mails and folders for an account while still totally shutting down the associated e-mail address? I would like to continue referencing, replying to (using a different e-mail address), and adding new e-mails to the folders as I have them already set up under my old e-mail address. In sum, is there a way to tell Thunderbird that I want to keep the email address and all its working folders on my computer, but that the e-mail address is no longer live? (What I did to date is put a wrong setting in the e-mail's set up, so it is not connecting to the server--not receiving all the junk e-mails I don't want or accidentally sending any under that address--but then, whenever I open Thunderbird, I have to go through the various error messages of how the e-mail address is not connecting) Thank you so much for any help you can offer!
