Office 365 and Azure Active Directory Auditing Overview Configuring Office 365 and Azure Active Directory auditing Reports and Searches

Disable a template

Disabling a template temporarily stops auditing activities without having to remove the template.

* 
NOTE: Change Auditor stops collecting events if a license expired, the template is disabled, or the agent stops. After you apply a valid license, enable the template, or restart the agent Change Auditor collects available events from the tenant that were missed.
To disable an auditing template
1
On the Office 365 Auditing page, use one of the following methods to disable an auditing template:
•
Place your cursor in the Status cell for the auditing template to disable, click the arrow control, and select Disabled.
•
Right-click the template to disable and select Disable
The entry in the Status column for the template changes to ‘Disabled’.
2
To re-enable the auditing template, use the Enable option in either the Status cell or right-click menu.

Delete a template

NOTE: When you delete a template, the web application created in Azure Active Directory remains. You can delete the web application using the Azure management portal.
To delete a template
1
On the Office 365 Auditing page, select the template to delete and choose Delete | Delete Template.

Office 365 Auditing Wizard

To audit Office 365 Exchange Online, SharePoint Online, and OneDrive for Business you must first create an auditing template and select an agent. For Exchange Online, you need to also define the type of events to audit.

For details on the integration points and process required to audit an organization, as well as auditing and agent considerations, see Deployment requirements.

Additional notes
•
Office 365 Exchange, SharePoint and OneDrive auditing templates created in the Windows client defaults to 7 days (168 hours) of historical event collection. Historical event collection includes only mailbox auditing types previously enabled.
•
Due to enhanced security measures, basic authentication is no longer supported for Office 365 auditing; certificate authentication is now required.
If you choose to create the required web application when you create the template, you can select to generate a self-signed certificate (default) or use a valid certificate from your personal certificate store. This will result in a properly configured web application.
•
If you choose to use an existing web application when you create a template, you will need to specify the application ID, application key, and a valid certificate. For required configuration, see Using an existing web application.

The following table provides details on how to create a template and the required web application so you can begin to audit the Office 365 activity. Also included are the details on how to edit an existing template.

When you remove a service, the agent will no longer audit its activity. If you later enable auditing, you will not be able access events generated when auditing was disabled.

Auditing activity selection page

Define or edit the types of activity to audit.

For a new template, before you can select to audit individual mailboxes or update the configuration to audit owner events, you need to select Finish to create the template.

NOTE: When Change Auditor creates a template with default settings, it turns on mailbox non-owner activity auditing settings for every mailbox in your tenant.

When you disable this option:

•
Mailbox non-owner activity auditing settings for every mailbox in your tenant will be disabled as well.
•
Only the mailboxes specifically added to the template through your selection will be audited. This may affect other systems that rely on having auditing enabled.
NOTE: When you add/remove individual mailboxes for auditing or select to enable/disable owner auditing, the changes are saved immediately. They are effective after the agent configuration is updated.
NOTE: If you change the mailbox display name, e-mail address, or UPN for a mailbox that is in a template, the auditing of the mailbox continues; however, the old mailbox settings display in the Change Auditor template. To see the new values, remove the mailbox and add it again.
IMPORTANT: It is recommended that you select owner auditing for critical mailboxes only. Owner auditing for a large number of mailboxes produces many events that may affect performance.

You can choose from the following:

Administrative Activity

•
All administrative events: This includes remote PowerShell connections to the mailbox, or any action in the web administration portal for the Office 365 Exchange Online organization.

Mailbox Activity

For mailbox activity, you have the option to set mailbox auditing settings or use the settings that have been configured in the Exchange Online tenant.

Set tenant mailbox auditing settings
•
Select All mailboxes for non-owner events
By default, only activities performed by users other than the mailbox owner (non-owner activity) are audited. You can however, disable this option and audit only specific mailboxes.

4
Click Next to optionally specify the generic events to exclude from auditing based on their operations. The operations are visible in the "Activity Name/Operation" column of the Office 365 built-in searches. Generic events are dynamically created when associated activity is detected that does not have a corresponding event defined in Change Auditor.
5
Click Finish to apply the updates. When the agent’s configuration is updated, it may take some time (approximately 1 second per mailbox) for it to be applied and the auditing to start after a template is created or modified.

Managing Azure Active Directory templates

Managing Azure Active Directory templates

Change Auditor for Active Directory simplifies the audit process by tracking, auditing, reporting, and alerting on activity in Microsoft Azure Active Directory that impact your environment. Change Auditor correlates activity across the on-premises and cloud directories, providing you a single pane-of-glass view of your hybrid Active Directory environment and making it easy to search all events regardless of where they occurred.

You can generate intelligent and in-depth reports, protecting you against policy violations and avoiding the risks and errors associated with day-to-day modifications.

Change Auditor audits activity that corresponds to the events in the Azure Active Directory audit logs, sign-in activity report, and risky sign-ins report.

For a list of events, their description, and default severity see the Change Auditor Office 365 and Azure Active Directory Event Reference Guide.
