Turn on error logs in Skype for Business

An error log is an ongoing record of the internal operations of a computer. Usually, logging levels are set by your support team when your software is installed and most of the time, these options don’t need to be changed. But occasionally you may be asked to send an error log to help analyze a problem in Skype for Business or Windows. Then you'll need to know how to change the settings and collect error information.

Having trouble signing in to Skype for Business?

If you’re unable to sign in to Skype for Business, there are some things you can try yourself before contacting your support team. On the main Skype for Business Sign in page, click Need help signing in? for suggestions. If you’re still having trouble, you can contact your support team and follow their instructions, which may include turning on error logs.

Select a logging level for Skype for Business

Important:  Before you change Skype for Business logging settings or enable Windows event logging, review the Privacy statement for Microsoft Lync 2013 Products.

  1. On the Skype for Business main window, click the Options button, and then click the General tab.

  2. In the Options window, under Help your support team help you, click the drop-down arrow next to Logging in Skype for Business, and select the logging level you want:

    • Full: Creates a log file that contains detailed information.

    • Light: Records summary information and gathers information about specific errors.

    • Off (default): Records no information.

Locate and gather information from the Skype for Business log file

  1. In File Explorer, navigate to the Tracing folder in your user profile directory—for example, C:\Users\<your_alias>\AppData\Local\Microsoft\Office\15.0\Skype for Business\Tracing. (If you’ve just enabled Skype for Business logging, you’ll need to sign out of Skype for Business and then sign back in for the log files to be created.)

  2. Compress (or zip) the Tracing folder.

  3. If directed to, send the compressed folder to your support team.

Enable or disable Windows event logging

On the General options window, under Logging, select (to enable logging) or clear (to disable logging) the check box next to Also turn on Windows Event logging for Lync to collect troubleshooting info.

View and gather information from the Windows Event Log

  1. In Windows 8.1, click the Windows logo, type Event viewer, and then choose View event logs.

  2. In the Event Viewer window, in the pane on the left, double-click Windows Logs, and then click Application.

  3. Double-click the listing for the Skype for Business error you’re trying to track down (usually the most recent Skype for Business error, or towards the top) to display the error details.

  4. If directed to do so by your support team, in the Actions pane, click Copy then Copy details as text. Paste the error information into a text file or email message to send to your support team.
