1. Sync to your Desktop PIM (Outlook, etc). This will keep your appointments, contacts, etc.
2. Find your backup folder at /program files/palmone/'yourname'/backup. Rename this folder to 'OldBackup'
3. Hard reset your Treo
4. Sync the empty Treo and select your user name when prompted.
The sync will pull all your Outlook data, but none of the previous items.
Good Luck!
