An Organization is a group that you create in your Hosted Exchange Email account so that you can manage and organize your mailboxes, email forwarding, contacts, etc. Members of an organization share a common Global Address Book. Therefore, all of the members of a particular organization have access to the same contacts and distribution lists, allowing them to collaborate. You may have one organization that consists of the members of your sales force. You may have another organization that consists of all of your Division Managers.
