Outlook Calendar Sharing without Exchange Server

S

Shafiee

Hi,

I have written this code... to share the outlook calendar between two
computer. The code simply copies the calendar data from one computer to an
access database, which the other computer will use to load the appointments
from and vice versa. I need someone out there to test the code, and suggest
modifications, and the best way to run it without the end users knowledge.

To test it, you need to paste the code to a .vbs file, set up a system DSN
called "SharedAppointmentData" pointing to an access database with a table
named "Appointments" which contains the fields "EntryID, StartDate,
StartTime, EndDate, EndTime, Subject, Location, EntryID1".

Any suggestion is appreciated.

Best Regards,
Shafiee.

Here is the code:

Dim amptitem

Dim olFolderCalendar
Dim MAPINamespace

Dim conAppointments
Dim rstAppointments

Dim strSQL


olAppointmentItem = 1
olFolderCalendar = 9

on error resume next
