I have an 8110 (very nice...) and am running Outlook against a remote Exchange server which Outlook copies emails from to local folders. My Outlook has a local calendar and an remote / online calendar which resides entirely on the Exchange server.
When I sync via Bluetooth and Desktop Manager (v4.7), it will only sync with my local calendar. Can I get it to sync with the remote one instead as I do not really use the local one?
