SYMPTOMS

Consider the following scenario:
  • You deploy a custom application in the Microsoft Lync Server 2010 environment. You do this by installing a Microsoft SIP Processing Language (MSPL) script on the Lync Server 2010 front-end server. The MSPL script uses the QueryCategory function to verify the user status.
  • A Lync 2010 user invites another Lync 2010 user for an instant messaging session.
  • You verify the corresponding log in Event Viewer.
In this scenario, the log displays a warning message that states that the QueryCategory function returns a NULL value instead of the presence information as a string.
