Configure Exchange Administrator Audit Logging Settings

To be able to audit and report who made changes to the Exchange servers in your on-premises infrastructure, or to Active Directory via the Exchange, ensure the Exchange Administrator Audit Logging (AAL) settings are configured as follows:

Setting Value Comment
AdminAuditLogEnabled True Enables audit logging
AdminAuditLogAgeLimit 30 Determines how long audit log entries will be retained (default is 90 days)
AdminAuditLogCmdlets * Instructs the program to create a log entry for every cmdlet that is run.
LogLevel Verbose Sets logging level.
ExcludedCmdlets

*-InboxRule

*-MailboxAutoReplyConfiguration

Set-MailboxAuditBypassAssociation

Set-MailboxCalendarFolder

Set-MailboxFolderPermission

Set-MailboxConfiguration

This list of exclusions is set up as explained in step 3 of the procedure below.

You can configure these settings automatically using Netwrix Auditor, as described in Active Directory: automatic configuration section.

To configure them manually, refer to the procedure described below.

NOTE: You can perform this procedure on any of the Exchange servers, and these settings will then be replicated to all Exchange servers in the domain.

To configure Exchange Administrator Audit Logging settings

  1. On the computer where the monitored Exchange server is installed, navigate to Start Programs Exchange Management Shell.

  2. Execute the following command depending on your Exchange version:

    • Exchange 2019, 2016 and 2013

      Set-AdminAuditLogConfig -AdminAuditLogEnabled $true -AdminAuditLogAgeLimit 30 -AdminAuditLogCmdlets * -LogLevel Verbose

    • Exchange 2010
    • Set-AdminAuditLogConfig -AdminAuditLogEnabled $true -AdminAuditLogAgeLimit 30 -AdminAuditLogCmdlets *

  3. To reduce server load, you can exclude the cmdlets listed in the table above from Exchange logging. For that:

    1. On the computer where Netwrix Auditor is installed, browse to the %Netwrix Auditor Server installation folder%/Active Directory Auditing folder, locate the SetAALExcludedCmdlets.ps1 PowerShell script file and copy it to Exchange server.
    2. In Exchange Management Shell, run this script using the command line:

      <Path_To_SetAALExcludedCmdlets_File>.\SetAALExcludedCmdlets.ps1

    3. NOTE: Make sure your policies allow script execution.
