Questions and answers

  • What is a .UCCAPILOG file and what is its purpose?

    A .UCCAPILOG file, also known as Unified Communications Client API Logger file, is a file format used by Microsoft Lync and Skype for Business applications. It is generated by the Unified Communications Client API (UCC API) logging feature, which is a debugging and troubleshooting tool.

    The purpose of the .UCCAPILOG file is to capture and store detailed logs of the communications and interactions between the client application and the server infrastructure. These logs can include information about call setup, instant messaging, presence updates, audio/video quality, network connectivity, and other relevant data.

    .UCCAPILOG files are typically used by support personnel or developers to diagnose and troubleshoot issues related to the Lync or Skype for Business client applications. By analyzing the logs, they can gain insights into the underlying communication protocols, identify errors or performance bottlenecks, and determine the root cause of problems.

    Users can enable UCC API logging in the client application settings or through registry modifications. Once enabled, the logs are saved as .UCCAPILOG files, which can be opened and analyzed using specialized tools provided by Microsoft or third-party software.
