That is exactly why we created the Connector for Microsoft Exchange. With it, you can access almost all information from your personal mailbox. The Connector puts you in a position to use this information for almost any application you'd like.
That means you could, for example, display a table in your CMS that accesses your personal mailbox, or just your inbox or outbox and then lists all mails that have the customer number of the currently selected customer in the subject. Or you can add a contact to your personal address book with a simple mouse-click.
You do not work with copies of the data but access your mailbox in real-time, or even mailboxes from other users where they have provided you with access permission. Even though the Connector for Microsoft Exchange can be used to access all elements of the Exchange Server and your personal mailbox, the Connector is neither a "second Outlook WebAccess" nor a replacement for Outlook.
