You are a messaging professional. Your company is deploying a Microsoft Exchange Server 2007 messaging system. Mailbox server and Hub Transport server have been deployed.

The company uses the domain name contoso.com for all e-mail addresses.

Users access their mailboxes by using Microsoft Office Outlook 2003.

Messaging administrators report that they must manually configure each users Outlook profile before the user can access the mailbox for the first time. Users have been requesting access to their mailboxes on the Internet.

Your Exchange Server 2007 deployment plan has been modified to include the following requirements:

Microsoft Outlook Web Access (OWA) will be used for access to mailboxes on the Internet.

Outlook will be used for access to mailboxes only from the companys internal network.

Users must be able to configure their own Outlook profiles by using their e-mail address and password.

The messaging environment must not be made less secure than necessary to implement the other new requirements.
