accessing exchange tasks and calender

[RussellDonders]

Hi,

I work in an organisation that uses exchange server for all email, and also maintains tasks lists and calender via outlook/exchange.

I am a developer responsible for a portal for the organisation and one of the things I would like to do is display the users current tasks/calender events (and maybe even new email messages) when they login to the portal.

I believe using vb.net this is possible, and of course the wonderful example of the web based version of outlook proves it is possible.

I am sure this has been done many times before but is a new venture for myself and if anyone could point me in the right direction as to where to start it would be appreciated.

To narrow it down to a question - how can i used vb.net to access the data stored in exchange server ?

Thanks,

Russell
