My IT guys were able to get my iPhone talking to our Exchange 2003 Server via IMAP earlier in the week - they had to turn on the IMAP service and open the appropriate port(s). Problem was, I was only seeing my inbox. If my path prefix was set to "INBOX", I saw the inbox plus any sub-folders under inbox. If the prefix path was set to "/", I saw only the inbox - no subfolders under inbox and no other folders at all.
After testing and surfing, I finally found a solution. This may or may not work for you but as I sit here now, I have full access to ALL of my Exchange folders. AND, it also solved the issue of items sent from my iPhone not going into my Sent Items on the server side and deleted not going into the server Deleted Items. [Still no solution to the riddle of items deleted from my inbox still leaving a copy in my server inbox).
I deleted all of my mail accounts on the iPhone. Just to be sure, I powered off the iPhone and then back on (I've been a Windows guy for too long, I guess - reboots are a way of life on the other side). I then set up a new IMAP account (not Exchange - I set it up as IMAP under Settings/Mail/Add Account/Other) using all of the same setting as my old account (which was set up as Exchange instead of Other). I did not change anything under Advanced. Presto! I checked my Exchange account and I had every folder - all of my private folders and even all of the Public folders on the Exchange server.
To solve the problem of making sure I got my Sent & Deleted Items to go into the appropriate Exchange folders, I went into Advanced mail settings on the iPhone and changed the default location of Sent & Deleted to their respective counterparts on the Exchange server.
