Office sharepoint 2007 mysite question

Dear All

We just started implementing Office sharepoint server 2007 and have a question.

We have exchange 2003 OWA here and when we setup the pages on sharepoint, we have a whole school site page and staff also have there own [B]mysite [B] page. At the moment the mysite page is fairly static and just has the generic sharepoint stuff. It has a myinbox for example which can link into exchange but the problem is so I have found that the user has to manually enter the exchange server address before they can see there inbox, calender etc.

Is there a way to roll this out for all users either via a sharepoint group policy or any other way.

Any help on this would be appreciated.

thanks
