I am running an Exachange 2010 server, latest version (14.01.0339.001). I have myself and a few other users getting email on their iPhones (3G/3GS/4G) over ActiveSync. It works wonderfully for the Inbox with Direct Push, but my problem begins when trying to view other folders in said user's account.
For instance, my mailbox has several folders beneath the Inbox and I have rules set up to sort things for me. After setting up my iPhone for Exchange, I could see the primary folders, Inbox, Trash, Junk, etc., but not any of the subfolders of Inbox. I tried all kinds of things to get this to work and it never did. Sometime later, I added a handful of folders beneath my Inbox for additional sorting, and as luck would have it, I checked my folder list on the iPhone and they were there! Not only that, but I could select them for direct push.
So, the question is, how do I get the previously existing folders to show up? Deleting and recreating them really isn't a viable option as they are numerous, but I am open to any ideas, with the exception of opening up IMAP.
