Evolution or equiv. sharing data on intranet

Hi All,

I am using evolution email and like the additional features such as contacts, tasks, appointment calendar etc.

I am using email via imap and have the system to save email in imap folders that can be accessed from any machine on the network.

Is there a way to configure the address book, contact lists, tasks list and appointment calendar to also utilize a common file/folder location from the local email server?

I am currently using dbmail + postfix to process email.

Is there other applications I might want to consider, thunderbird looks promising but I also need a windows app. that has the same functionality..
