Part of the value of unified communications- in fact a big part- is the unified part. With a Microsoft Unified Communications implementation, the Office Communications Server (OCS 2007) has to be able to communicate with the Exchange Server for a variety of converged communications reasons. One particulalry important reason though is Presence. OCS 2007 is able to sync up with Exchange and the user’s Outlook calendar and automatically update Presence. It also helps for co-workers or managers be able to see when an individual is free or busy when they want to schedule a meeting.
That became a problem recently for some organizations. Mike Stacy, Director of Professional Services for Evangelyze Communications, noticed a string of communications or connectivity issues between his OCS 2007 server and his Exchange server. Ultimately, he determined that a recent update to the .NET Framework was to blame and found the Microsoft KnowledgeBase article he needed to resolve the problem. Check out Mike’s blog post for more details on the problem(s) and the solution: Communicator Exchange Connection Issue.
