Update And View Your Contacts From Anywhere
Edit a contact once and you don't have to make the same change on another software package or hardware device. Your ScheduleWorld global addressbook will take care of keeping everything in sync. Change a contact in Outlook, do a sync (can be scheduled to happen automatically) and the updated contact will be available on your cell phone, your iPod, OS/X mail, Thunderbird, Evolution, and more. You can find out more details about this here: ScheduleWorld SyncML

Works With Most Common Email, Calendaring, and Contact Applications
Outlook, OS/X mail, Thunderbird, Evolution, KMail, Netscape mail, SyncML-capable cell phones, iPod, and more.

Open Standards Support - LDAP and SyncML
The reason why the ScheduleWorld Global Addressbook is so widely supported and works so well with so many applications is because it is based on the open standards LDAP (v3) and SyncML (1.1 and 1.2). These are the defacto industry standards for addressbooks and synchronization.
LDAP setup and configuration information.

Autocomplete
A number of applications (for example: Thunderbird and OS/X mail/addressbook) have a great feature where you just have to type the first 3 letters of an email address and they will query your ScheduleWorld global addressbook in real-time to get and display possible matches. It doesn't matter if you are on your laptop, your desktop, at work or at home; all you need is connectivity to the Internet.
