Am I correct in thinking that only IMAP syncs properly - ie read on your phone, read on webmail and outlook, and being able to download the same email to more than one device
No, you can do this with a POP client, it's just that by default, as a result of POP being 2 million years old from the days when people only had one computer, most POP clients by default send a "delete from server" instruction after downloading mail to the local machine. You can set it to do otherwise.
