Had Desktop and Laptop set up With windows 7 and Live Mail. Laptop crashed so had to reset to factory config and reload all.

Calendars don't sync. Desktop has calendar name Dc.rr(cmarshall) based on old email provider. Now with verizon but calendar name did not change with new email accounts. Laptop reload established new calendar name Verizon(annmar3). How can I get the desktop calendar on the laptop and get them to sync ? Must the default accounts be the same on both machines?
