Let me explain as I know there are and have read many posts on syncing and Outlook, etc. For thos of us who are on Exhange at work we do have the option of creating the Exhange account on the iPhone, which is nice but that doesn't sync with the Cloud. Outlook without exhange uses a local PST data file, which iTunes and MM can "see" and parse for email, Calnder and Conacts. However, when on Exchange the local file is a OST file which maintains the sync between the PC and Exchange server. It essentially contains the same data as a PST would. So I'm wondering if this may be contributing to the breakdown of syncing Outlook (on Exchange) and MM? I ask because I can sync up fine from home, but not from work - and all the other posts about Outlook don't seem to nail down whether they're on Exchange or not.
