what are you trying to "sync" ? you can have email pushed to your device (but most Hotmail accounts do not work as you will see from the conversations above #2, #9, #12, #13..etc, and MANY other threads on this forum), but sync'ing is different. MSN/Hotmail cannot sync anything (sync email 2-way, address book, calendar, notes). For that you would need a BES account (there are threads about BES if you wish to read them).
