when I added a NOOK to my laptop and smartphone, my carrier (Charter) instructed me to change the server from POP to IMAP so I could get the same emails on all three devices. We could not change the account so added a new account as IMAP, same email address as the other. But the old account with the email address remains in the column on the left of the page, and when it sends/receives I get a warning box that the POP account could not be accessed. Of course not, it has been changed! But when I go to remove the account it says it will delete the email account which is the same name as the new one. I am afraid I will lose the new account and all the archived emails I moved to it. Suggestions?
