OpusFlow (est. 1999) sold the first Exchange Group Calendar license back in Feb. 2003 to Texas Medical Association working with Exchange server 2000. That version used the Com+ and cdoex interface to talk to exchange server which was a big improvement over the CDO 1.21 interface that we had to use in Exchange server 5.x. In June 2008 this version was rebuilt to support 64 bit Exchange server 2007 and had its last update in 2009. Current version 3 was released in Jan 2011, built from scratch based on the Exchange Web Services interface and has been updated 58 times since then. Version 3.x works with exchange server 2007 and up.
