Turn on error logs in Skype for Business (Lync)

You can select error logging options on the Skype for Business (Lync) General Options window. 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 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 (Lync) or Windows, in which case you may need to know how to change the settings and collect error information, as described in this article.
