I've managed to sync Outlook 2010 (the public beta version) with my N900 using Nokia PC Suite 7.1.40.1. After some experimentation (see below), I established an initial sync to replace everything in the mobile device with data from Outlook. Contacts seems to have sync-ed fine. Calendar is OK (I have ~5000 entries dating back 10 years) - although a 100 or so entries were apparently refused by the N900. I haven't got to the bottom of this, but it seems to be entries before about the year 2000 that failed to transfer. Notes apparently sync-ed ok, but there doesn't seem to be any application on the N900 to handle them, so I don't know where they have been sent! Before using PC Suite to sync, I used the N900's Transfer & sync utility to pull all my contacts from my E71 (over Bt). Transfer of my large calendar failed after about 2700 entries had been received. Simon.
