Note: The Import and Export functions do not support Outlook Express. You will need either Outlook97 or Outlook98 to share schedule information.
Also: There is no way at present to synchronize Outlook's "Task List" with Yahoo! Calendar's "To Do" list.
Sharing information between Outlook and your Yahoo! Calendar is currently done through the import/export function.
Outlook support the Comma Separated Value (CVA) format. However, Yahoo! Calendar also supports the Date Book Archive (DBA) format used by Palm devices.
Since the import, export and synchronization of calendar information is not a simple task, we recommend that you have some experience with this sort of file transfer before attempting to sychronize your Outlook calendar with your Yahoo! Calendar.
