How to search for and view eDiscovery activities
Currently, you have to do a few specific things to view eDiscovery activities in the audit log. Here's how:
Note
For a limited time, this classic eDiscovery experience is also available in the new Microsoft Purview portal. Enable Compliance portal classic eDiscovery experience in eDiscovery (preview) experience settings to display the classic experience in the new Microsoft Purview portal.
Go to the Microsoft Purview compliance portal and sign in using your work or school account.
In the left navigation pane of the compliance portal, select Audit.
In the Activities drop-down list, under eDiscovery activities or eDiscovery (Premium) activities, select one or more activities to search for.
Note
The Activities drop-down list also includes a group of activities named eDiscovery cmdlet activities that will return records from the cmdlet audit log.
Select a date and time range to display eDiscovery events that occurred within that period.
In the Users box, select one or more users to display search results for. Leave this box blank to return entries for all users.
Select Search to run the search using your search criteria.
After the search results are displayed, you can select Filter results to filter or sort the resulting activity records. Unfortunately, you can't use filtering to explicitly exclude certain activities.
To view details about an activity, select the activity record in the list of search results.
A Details fly out page is displayed that contains the detailed properties from the event record. To display additional details, select More information. For a description of these properties, see the Detailed properties for eDiscovery activities section.
If desired, you can export the audit log search results to a CSV file, and then use the Excel Power Query feature to format and filter these records. For more information, see Export, configure, and view audit log records.
eDiscovery activities
The following table describes the Content Search and eDiscovery (Standard) activities that are logged when an administrator or eDiscovery manager performs an eDiscovery-related activity using the compliance portal. Some activities performed in eDiscovery (Premium) may be returned when you search for activities in this list.
Note
The eDiscovery activities described in this section provide similar information to the eDiscovery cmdlet activities described in the next section. We recommend that you use the eDiscovery activities described in this section because they will appear in the audit log search results within 30 minutes. It may take up to 24 hours for eDiscovery cmdlet activities to appear in audit log search results.
