Admin Guide: Azure Information Protection unified labeling client files and client usage logging


Are you looking for Microsoft Purview Information Protection, formerly Microsoft Information Protection (MIP)?

The Azure Information Protection add-in for Office is now in maintenance mode and will be retired April 2024. Instead, we recommend you use labels that are built in to your Office 365 apps and services. Learn more about the support status of other Azure Information Protection components.

After you have installed the Azure Information Protection unified labeling client, you might need to know where files are located and monitor how the client is being used.

Usage logging is supported with the Azure Information Protection unified labeling client version 2.12.62 and higher.

Turn on usage logging

To turn on support for usage logging for both the unified labeling client and scanner, set the registry key as follows:

  • Registry path: HKEY_CURRENT_USER\SOFTWARE\Microsoft\MSIP\EnableLoggingAuditEventsToEventLog
  • Type: DWORD
  • Value: 1

Log file locations

Client and scanner log files are located in the following locations on your unified labeling client machine:

  • \ProgramFiles (x86)\Microsoft Azure Information Protection (64-bit operating systems only)
  • \Program Files\Microsoft Azure Information Protection (32-bit operating systems only)
  • %localappdata%\Microsoft\MSIP

Client-side usage logging


Client-side usage logging is currently in PREVIEW. The Azure Preview Supplemental Terms include additional legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.

The unified labeling client logs user activity to the local Windows event log Applications and Services Logs > Azure Information Protection.

Logged events for the client include the following information:

  • Client version

  • IP addresses of the signed in user

  • File name and location

    • Remove label: Information ID 104

    • Discover label: Information ID 106

The events for Outlook warn, justify, and block messages require advanced client settings. For more information, see Implement pop-up messages in Outlook that warn, justify, or block emails being sent.
