I have switched ISP providers, going from Primus to Bell. On my Thunderbird, Primus was POP. Bell is IMAP. When I discontinue my billing service with Primus, do I risk losing the hundreds of folders and the emails and valuable information they contain? If this risk exists, is it avoidable and how would I go about this? Basically, I'd like to be able to see the folders and mail boxes created under the Primus account in Thunderbird, and when I discontinue the Primus service be able to see and have access to those folders etc., when using Bell. Thanks to anyone and everyone who may respond to this call for help.
