Lotus Domino Messaging Express offers smaller enterprises complete business messaging and group scheduling. 

Lotus Domino Collaboration Express adds all of the custom application power of Domino.

Both support the full range of client access types, from simple Web mail and browser applications, through standards-based POP3 and IMAP e-mail, to rich, dynamic HTML-based messaging, to IBM Lotus Notes or Microsoft Outlook. Users can have multiple types of access to the same mail and applications, such as Notes e-mail at the office and Domino Web Access from airport Internet kiosks.

Lotus Domino Utility Express provides virtually unlimited access to collaborative applications (not individual mail files), making it a perfect choice for high-function Web sites, intranet or extranet self-service applications, and Internet communities. You can choose to access your Domino applications through a Web browser or through a separately purchased Lotus Notes client license to make applications available to your company's internal users, as well as to external users, as needed.
