Working with Microsoft Exchange

[cesarcesar]

Ahoy,

I'm trying to learn more about working with Microsoft Exchange data using PHP. Can anyone suggest some links for more info about this topic?

In particular I am looking to
LIST Set/Remove/Edit Calendar entries.[/LIST]
LIST Read a users Contacts for name and email. The data will then be placed into a CMS. [/LIST]

I have Google'd much about this topic and have only found one good source of info, http://www.troywolf.com/articles/php/exchange_webdav_examples.php. Are there more?

Thanks much.

Cesar
