If you are setting it up as a POP3 account again then it should default to leave on the server once downloaded.
If you want to you can set it up manually and you would have to enter the settings etc your self but as long as you are sure it is an IMAP account I would just leave it to the automatic set up.
I just wanted to thank you publicly for giving me the confidence to reconfigure TBird. I set it up many years ago using the POP3 protocol, as I didn't know any better. It has always been of limited use to me as it only ever synced my 'INBOX', none of my sub-folders, or indeed, my 'sent' folder. IMAP is an eye opener.
It took almost 12 hours to fully sync, which I suppose isn't unreasonable for a 30+ year old account, and in excess of 200,000 messages now including sub folders and sent folder!
I can see it becoming much more usable now, and though I'll still frequently use WebMail, it has given me another option. I love the novelty of seeing all my folders replicated! Again, thank you...
