ExpressMirror is a synchronization tool for Microsoft Outlook Express and Palm Desktop.

It allows you to synchronize Outlook Express address book with Palm Desktop address book / contacts. Which you may synchronize with your Palm hand held devices later by HotSync.

By using ExpressMirror, it could be very easy to keep your Palm, Palm Desktop and Microsoft Outlook Express address book information up to date.
