By default, OfficeTalk uses its own proprietary mail transport when sending mail from one OfficeTalk user to another. Additional integrated mail services are provided to let you send and receive mail to and from organisations that use Microsoft or Lotus e-mail applications. An Internet mail service is also provided which lets every OfficeTalk user send and receive Internet mail.
The mail services, provided with OfficeTalk, make it possible to integrate OfficeTalk seamlessly into any organisation which uses an existing e-mail system.
Further integration is provided with Microsoft Exchange and Microsoft Outlook. OfficeTalk is supplied with electronic forms which may be installed into Microsoft Exchange or Microsoft Outlook. Such forms enable OfficeTalk users to invite Exchange or Outlook users to meetings and to assign them tasks, all through a form-based interface.
