In the Beginning - Office Communications Server (OCS) 

Our story begins in the early 2000s when Microsoft recognized the growing need for efficient communication within organizations. In 2007, Microsoft introduced Office Communications Server (OCS), laying the foundation for what would later become Microsoft Teams. OCS was an on-premise Unified Communications (UC) platform designed to enhance enterprise communication through features like instant messaging, presence, and conferencing. 

Lync and the Birth of Modern Collaboration 

Fast forward to 2010, and Microsoft rebranded OCS to Lync Server, signaling a shift towards a more integrated and user-friendly communication platform. Lync was instrumental in introducing video conferencing, web conferencing, and enterprise voice capabilities. 

Skype for Business - Bridging the Gap 

In 2015, Microsoft acquired Skype and incorporated its features into Lync, giving rise to Skype for Business. This new version retained Lync's enterprise capabilities while integrating Skype's user-friendly and consumer-oriented communication features. It was a significant step towards the vision of unified collaboration. 

Enter Microsoft Teams 

In March 2017, Microsoft officially launched Microsoft Teams, representing a quantum leap in the world of collaboration. Teams was designed to be a hub for teamwork, combining persistent chat, file sharing, and integrated applications in a single platform. It aimed to provide a digital workspace where teams could collaborate seamlessly, making it easier to communicate, share documents, and organize meetings.

  • Guest Access: Teams allowed external collaborators, making it even more versatile for inter-organizational communication. 

  • App Integration: Microsoft embraced a robust third-party app integration strategy, expanding the capabilities of Teams further.
