I was wondering: is it true that Thunderbird cannot show folders on hotmail account that were created using your internet browser?
As far as I can tell it can't. Hotmail doesn't do imap. Thunderbird can only get mail from hotmail via the pop3 protocol which doesn't have any folder support. iPhones & iPads seem to be able to use some Exchange protocol - thunderbird and apple mail can't. Protocol wars are painful.
