Microsoft Lync, formerly known as Office Communications Server (OCS), presently known as Skype for Business, integrates enterprise-ready instant messaging, presence, conferencing, and unified communications in a single offering. Lync comes in a Standard Edition for smaller companies and an Enterprise Edition for larger companies.
