Have you ever been in a meeting and then started receiving instant messages or phone calls because your presence shows you as available? When Communicator uses Microsoft Office Outlook as its personal information manager, it can change a user’s presence automatically based on Microsoft Exchange Server free/busy information. However, sometimes Communicator is not updated or showing the correct presence because of what is in the user’s free/busy information. This article discusses basic and advanced troubleshooting steps to resolve these types of conflicts.
Before we begin troubleshooting, it is important to understand how Communicator pulls the free/busy information from Exchange. Figure 1 illustrates the flow of information when Communicator pulls free/busy calendar information from Exchange and Outlook.
