Is there a way to delete all contacts from the address book besides doing it one at a time?

if your just looking to do only your contacts then no..... if you don't mind wiping your handheld which will delete all of them then yes there is a way.... use the search feature above because I told someone else how to do it yesterday

YES, there is a way I did it on mine a week ago. Do the following:

Open >Desktop Manager<
Go to >Backup and Restore<
Click >Advance<
Now on the handheld Database Side
Select >Address Book<
Click >Clear<

If you are using BES or BIS, delete or move them from your outlook contacts

Then resynch if using BIS
