HyperOffice has launched a public trial of its business collaboration tools that connect the iPhone to corporate email, contacts, calendars, tasks and notes.

The collaboration tools are built into HyperOffice and operate as an alternative to Microsoft Exchange. HyperOffice synchronises the iPhone email client with Microsoft Outlook, giving business users wireless access to secure corporate messaging and collaboration services. The public beta includes a 30-day free trial of HyperOffice,

"People really want to use the iPhone as a business tool," said Farzin Arsanjani, president of HyperOffice. "You can't do that until you solve two problems. First, it is difficult for the large enterprise to deploy the iPhone to corporate road warriors without native support for Microsoft Exchange," said Arsanjani.

"Second, if you are using Outlook to run and grow your business, how do you begin sharing calendars, contacts, documents and tasks - not just email - without Exchange, especially when the iPhone does not work with Exchange?

"These are the two stumbling blocks that HyperOffice removes."

The developer's HyperShare is a gateway tool built into HyperOffice, iPhone users can continue to use Outlook, but share calendars, contacts, documents and tasks - both with and without Microsoft Exchange.

Web application HyperShare is a one-time download to the desktop. It migrates Outlook contacts, calendars and email folders, then automatically delivers email to the email application built into the iPhone, replies and new messages are relayed back to Outlook or to the corporate Exchange server.
