Fake Exchange

[Carrotman]

Hey,

I've just taken over the management of a computer suite that gets used for training.

The Outlook training is a little bit of a shambles as we're currently using yahoo email accounts(!)

Ideally I would like an Exchange Server as this mimics our clients' set-ups, but setting this up would be prohibitively expensive, and beyond my skill.

Anyone know of anything that behaves like Exchange but cheaper and runs on WinXP?

The essential functions I need are:

Shared address book

Shared calendars

Thanks
