Hi,

The Modification Resolution logs provide a description of the actions that Outlook took during a conflict situation. To stop the Modification Resolution logs, configure the following registry key and set the value to 0:

Key: HKEY_CURRENT_USER\ Software\Microsoft\Office\15.0\Outlook\Options

DWORD: EnableConflictLogging

Value: 0 = Never save Modification Resolution logs

          1 = Always save Modification Resolution logs

          2 = Save Modification Resolution logs when a "critical conflict" occurs

Hope this helps.

Regards,
