I have a gmail address set up through TB on one old computer as POP, and two other devices as IMAP. On the other devices I can access all gmail folders in real time. The old computer only shows the inbox, and 'sent mail' from that computer only. I would like to change TB on the old computer to IMAP so they can all work the same and access sent mail etc from the server. Instructions on making the change seem clear but I want to clarify if I can it without changing my email address. This sentence confuses me: "If you have created a new email account that uses IMAP, you cannot delete your old POP account without deleting your email address" Does the first part mean "a new email account with a different email address" or "a new IMAP account with the same email address"?
