Getting mail subfolders to notify of new mail?

Emergency medicine resident.

Late to your thread but came across it while searching.

My understanding:

For Hotmail/Outlook, if syncing via ActiveSync, I would think the same would be true. Should be able to go into the account's settings and specify which folders you want to sync automatically. I am not a Hotmail/Outlook user and so cannot speak from experience.

For Gmail, if still using ActiveSync before they took that away (which at this point means you would have to be using a device on which you set up your account before their "deadline"), you can sync any folder, no problem.

For all other IMAP accounts / like Gmail as IMAP, you may be out of luck. That said, there is another thread which talks about adding subfolders to the main folder page for iCloud accounts to apparently have them push-enabled; that thread is here. I don't know if, or think, that would work with any other IMAP account since iCloud does have some degree of proprietary network connectivity, iirc. Could be wrong as I haven't tried it with my own Gmail account yet.
