Summary: This guide will talk about the evolution of the Domino Lotus Notes from IBM to HCL and its journey from the beginning. Also, we have brief details on the history of the Lotus Notes versions from 1.0 to 12.0 in this post.

HCL Lotus Notes or HCL Notes, formerly known as IBM Notes, is a great revolutionary in the email client domain. When its first version was released, 35,000 copies were sold after its first launch. Lotus Notes is a desktop-based email client that is widely adopted by businesses and organizations. It began its journey in the late 1980s as the most influential collaboration platform and has evolved significantly over the decade.

To run Lotus Notes, users need the HCL Domino Server (IBM or Notes Domino Server) in their system. It offers facilities like sharing files, messaging, voice or video conferencing, document libraries, discussion groups, and business workflow. Moreover, this email client also allows users to configure IMAP or POP server email accounts on the Domino Server.

The Early Days of the Lotus Notes Development:

Before its first release in the year 1989, there were no email collaborative, file sharing or calendar managing solutions. However, businesses and organizations need such software to collaborate and communicate better for their smooth workflow. Let us now understand the detailed history of Lotus Notes before its first release.

  • In 1984, Ozzie founded a company called Research in Motion (RIM) (later known for creating BlackBerry).
  • Ozzie started working on developing the Lotus Notes email client in the year 1986. He began developing Lotus Notes to offer integrated email, file-sharing and calendar management tasks.
