Desktop Manager 4.6 I use this version, it's supposed to be more stable. Connect the USB cable from your computer to the 8830 and follow the onscreen instructions. After that from the main screen, click on synchronize. Than from the left hand column, under synchronize, click on synchronization. For the first sync, select a task and have the sync go from outlook to the device. Thereafter, have it as a 2 way sync. I hope this isn't to difficult to understand.
