How to Export Search Results in Microsoft 365 eDiscovery (Purview)

This guide explains how to export search results using the new Microsoft Purview eDiscovery (Premium) portal, replacing the legacy Security & Compliance Center and the retired eDiscovery Export Tool.

Prerequisites

• You are signed in to Microsoft Purview with an account that has the roles eDiscovery Manager and Compliance Administrator.
• Use Microsoft Edge (recommended) or Internet Explorer.

Step 1: Access Microsoft Purview Portal

• Go to https://portal.office.com/ and sign in with Global Admin credentials.
• Open a new tab and navigate to https://purview.microsoft.com.
• From the Purview home page, select eDiscovery (Premium).

Step 2: Create or Open a Search

Within your case, open the Searches tab to view or create searches. To start a new one, click Create a search. You can filter by keywords, date range, or specify the content sources such as Exchange mailboxes, SharePoint, OneDrive, or Teams.

Step 3: Run and Save the Search

• Select All mailboxes or specific content sources.
• Add conditions, such as Date or Keywords, to refine the search.
• Click Save & Run and enter a descriptive name for the search.

Step 4: Export Search Results

After the search completes, open it and select Export from the menu. In the Export flyout panel, configure the export options:

• Export name: Enter a descriptive name.
• Export type: Choose Export items with item report to include both data and summary report.
• Export format: Select Create PSTs for messages or Create .MSG files for messages.
• Package size settings: Default values are 5 GB per PST and 10 GB per ZIP package.
• Output options: Organize data per mailbox, include folder structure, and condense paths to stay under 259 characters.

Step 5: Monitor Export Progress

Open the Process Manager in the case to monitor export progress. You can track export name, status, completion time, duration, and creator.

Step 6: Download the Export Package

Once the export process completes, open the Overview tab, locate the export package, and select Download packages. Export links are unique to your session and should not be shared.

Best Practices for Downloading

• Allow pop-ups from Microsoft Purview.
• Enable multiple automatic downloads in Edge settings.
• Use a local drive (not a network share) for downloads.
• Whitelist all required Microsoft 365 endpoints.
• Enable parallel downloading in your browser settings for large exports.
• Consider using a download manager to resume interrupted downloads.

Legacy Notice

The Microsoft Office 365 eDiscovery Export Tool is now retired. All exports are performed directly through the Microsoft Purview portal interface.
