Exchange Synchronisation

Question

Good Morning! I'm currently working on a project to merge the appointments of our companies employees with a public calendar. I found some tutorials and code snippets showing the use of CDO to access Exchange mailboxes. So i managed to list all the exchange accounts out of active directory and connect to the exchange server. But i don't have any ideas on how to work with the ADODB queries... What i wanna do is: Open the calendar of a mailbox, iterate through all the appointments from date x to date y and create a corresponding appointment in the public calendar. Any help, suggestions or example on this would be highly appreciated ;) Robert
