Intune On-Premises Exchange Connector Log

Just a quick note for everyone missing the log files location of Microsoft Intune On-Premises Exchange Connector, seems like there is no documentation on where those files exists. and they are very useful for debugging this component.

This info came from a support case I’ve had with the on-premises connector 🙂


  • Log files are here – C:\ProgramData\Microsoft\Windows Intune Exchange Connector\
  • If you wish to enable verbose tracing for more advanced debugging do the following:
  1. Open the Exchange Connector tracing configuration file. The file is located at: %ProgramData%\Microsoft\Windows Intune Exchange Connector\TracingConfiguration.xml
  2. Locate the TraceSourceLine with the following key: OnPremisesExchangeConnectorService
  3. Change the SourceLevel node value from Warning ActivityTracing (the default) to Verbose ActivityTracing.
      <Key xsi:type="xsd:string">OnPremisesExchangeConnectorService</Key>
      <Value xsi:type="TraceSource">
            <SourceLevel>Verbose ActivityTracing</SourceLevel>
            <FileName>Microsoft\Windows Intune Exchange Connector\Logs\Connector.svclog</FileName>

It is important to note that the ActivityTracing setting should remain or be included with ANY value that is set for the setting.
