There is a rumor in the blogosphere that Microsoft may release an update to Office Communications Server 2007 this fall. The next major release of Office Communications Server is expected to be OCS 2009. However, according to at least one blog, Microsoft may release OCS 2007 R2 in Q4 of this year to update OCS 2007. As quickly as the unified communications landscape changes, an R2 of OCS 2007 would make sense. There are a variety of features and functions that customers want and need, and if Microsoft makes them wait until 2009 or later for the next major OCS release, those customers might invest in alternative solutions that meet their needs now. There is no confirmation of the rumor from Microsoft, and no details currently available regarding what updates or features might be included in R2.
