Microsoft has just released the following Knowledge Base articles (KB972041, KB972042) to address the incorrect calculations of license expiration dates for Office Communications Server (OCS) 2007 R2 and Office Communicator (OC) 2007 R2 Evaluation Edition. The current expiration dates were calculated based on build time, causing the OCS 2007 R2 and OC 2007 R2 Evaluation Edition to expire after June 13, 2009.

Microsoft has issued the fixes below to correct the issues. By applying this fix, the expiration date will be updated to one hundred eighty (180) days after the initial installation of OCS R2 or OC R2 Evaluation Edition, as stated in the license terms for these applications.

Microsoft encourages its customers to apply necessary updates in their evaluation environment to take full advantage of the evaluation period.
