Microsoft on Friday finished development on a new version of its Exchange messaging server.

The company said it has shipped Exchange Server 2007 to manufacturing.

This latest release comes only a week after the company celebrated its launch alongside significant new releases of the Windows client operating system (OS) and Microsoft Office.

Security, the mobile workforce and regulatory and policy compliance are three areas where Microsoft has made enhancements to Exchange 2007.

In the security realm, new built-in protection features include the ability for customers to purchase either on-premise antivirus software or a hosted version. As part of a new enterprise Client Access License (CAL) for the product, customers can purchase Microsoft's Antigen for Exchange antivirus software or Exchange Hosted Filtering services bundled with the Exchange CAL.

For compliance, Microsoft provides the ability to set email folder policies in Exchange to support compliance across the organisation. For example, server administrators can set up policies to prevent employees from different groups in the company – brokers and financial analysts, for example – from exchanging email. Administrators also can set up policies that automatically archive email messages pertaining to certain topics, or automatically delete other emails.

The new software also will allow users to send encrypted mail among servers running the product. Previously, extra set-up had to be done for this to happen.

For the mobile worker, Exchange 2007 allows users to search through a greater number of emails on devices. The new software also will allow a remote user, even without administrator privileges, to wipe all Exchange Server-fed data from a device if it is lost or stolen.
