HyperOffice, provider of Enterprise Collaboration Software and tools, launched a new public beta of its business collaboration tools. This second beta of HyperOffice for the iPhone includes usability enhancements and access to shared documents, using built-in tools that connect to corporate messaging systems and operate as an alternative to Microsoft Exchange and Sharepoint. Users of the iPhone with HyperOffice may also share group and project calendars with team members and clients who also use Outlook and HyperOffice. Users may retrieve, share, and update address books, projects and tasks, and manage documents with online storage, versioning, user rights, and commenting. HyperOffice also provides discussion groups, security and backup, and business-class email.
