Exchange group

I have 2 questions about Microsoft Exchange server 2003.

1. Is it possible to have contacts group to send message to multiple contact with a simple click?

2. Is it possible to have groups to send fax with Winfax or I'll have to create a Visual Basic application for that?

1.) You can create a Distribution List. This will contain any Contacts that you want to include in the group.
Then when you send an email you just set the To: field to the name of the DL.
