Hi Geoff,

Did you follow the steps on Apple's support site ?

	• The Exchange 2007 server must have Exchange Server 2007 Service Pack 1 Update Rollup 4 or later installed.  
	• You can have as many Exchange 2007 (EWS) accounts in Mail as you would like.
	• Exchange 2007 accounts use the Exchange Web Services protocol.

Since it uses the Web Service protocol, I have a suspicion that your account on the exchange server also needs to have Outlook Web Access (OWA) enabled.
Your tech guy should be able to check and configure that.

I used to use mail.app from OS X 10.6.x with our Exchange 2007 server without any issues.

The following link might also help :

If your account has OWA enable you can also use the webmail light. Usually you connect to it using :
https://exchangeserver.address/owa/

Success,

Ron Schemen

I tried for a few days to use Word (Oh, god, how can anyone make a word processor interface so unfriendly, even given the time they have had to work on it? Then I tried working on the Mac and transferring data to the PC using a flash drive ... the flash drive buggered up at a critical moment! Aargh!).

What I am thinking I can do is use Mail as the client for the local email operating through Exchange 2007. It looks possible. However, the (low level) tech and I couldn't configure it correctly.
