You're not alone, this also happened to me several months ago. At some point, PC Suite stops syncing new Outlook data to the N900. I always suspected it had to do with either (a) the amount of data--I have a LOT of data in Outlook, or (b) a certain number of syncs and it stops working. Ultimately, it is just a one-way sync as you say, which of course is no good for folks who keep their master information in Outlook. I was hoping with the new firmware PR 1.3 and Ovi Suite support, this might be resolved, but I can't get the Bluetooth to function with Ovi Suite. Cheers! Brad
