Commit a draft collection to a review set in Advanced eDiscovery

When you're satisfied with the items you've collected in a draft collection and are ready to analyze, tag, and review them, you can add a collection to a review set in the case. When you commit a draft collection to a review set, collected items are copied from their original content location in Microsoft 365 to a review set. A review set is a secure, Microsoft-provided Azure Storage location in the Microsoft cloud.

Commit a draft collection to a review set

  1. In the Microsoft 365 compliance center, open the Advanced eDiscovery case, and then select the Collections tab to display a list of the collections in the case.

    Tip

    A value of Estimated in the Status column identifies the draft collections that can be added to a review set. A status of Committed indicates that a collection has already been added to a review set.

  2. On the Collections page, select the draft collection that you want to commit to a review set.

  3. On the bottom of the flyout page, select Actions > Edit collection.

  4. In the edit collection wizard, click Next until the Save draft or collect page is displayed.

  5. Configure the following settings:

    1. Select Collect items and add to review set.

    2. Decide whether to add the collection to a new review set (which is created after you submit the collection) or add it to an existing review set. Complete this section based on your decision.

    3. Configure the additional collection settings:

      • Teams and Yammer messages: Select this option to add conversation threads to the collection that include the chat items returned by the search query in the collection. This means that the chat conversation that contains items that match the search criteria is reconstructed. This lets you review chat items in the context of the back and forth conversation. For more information, see Conversation threading in Advanced eDiscovery.

      • Cloud attachments: Select this option to include modern attachments or linked files when the collection results are added to the review set. This means that the target file of a modern attachment or linked file is added to the review set.

      • SharePoint versions: Select this option to enable the collection of all version of a SharePoint document per the version limits and search parameters of the collection. Selecting this option will significantly increase the size of items that are added to the review set.

    4. Configure the settings to define the scale of the collection to add to the review set:

      • Add all collection results: Select this option to add all the items that match the search criteria of the collection to the review set.

      • Add a sample of the collection results: Select this option to add a sample of the collection results to the review set instead of adding all results. If you select this option, click Edit sample parameters and choose one of the following options:

        • Sample based on confidence: Items from the collection are added to the review set will be determined by the statistical parameters that you set. If you typically use a confidence level and interval when sampling results, specify them in the drop-down boxes. Otherwise, use the default settings.

        • Randomly sample: Items from the collection are added to the review set based on a random selection of the specified percentage of the total number of items returned by the search.

  6. On the Review your collection page, you can review the collection settings that you configured on the previous page. Click Edit if you want to change them.

  7. Click Submit to create the draft collection. A page is displayed confirming that the collection was created.

What happens after you commit a draft collection

When you commit a draft collection to a review set, the following things happen:

  • If you created a new review set to commit the collection to, the review set is created and displayed on the Review sets tab in the case. The status of the new review set is Ready. This status value means the review set has been created; it doesn't mean that the collection has been added to the review set. The status of adding items in the collection to the review set is displayed on the Collections tab.

  • The collection search query is run again. This means the actual search results copied to the review set may be different than the estimated results that were returned when the collection search was last run.

  • All items in the search results are copied from the original data source in the live service, and copied to a secure Azure Storage location in the Microsoft cloud.

  • All items (including the content and metadata) that aren't located in custodian or non-custodian data sources are reindexed (in a process called deep indexing) so that all data in the review set is fully searchable during the review of the case data. Reindexing the content in a collection results in thorough and fast searches when you search or filter the content in the review set during the case investigation.

  • Encrypted SharePoint and OneDrive documents and encrypted files attached email messages that's returned in the search results are decrypted when you commit the collection to a review set. You can review and query the decrypted files in the review set. For more information, see Decryption in Microsoft 365 eDiscovery tools.

  • Optical character recognition (OCR) functionality extracts text from images, and includes the image text with the content that's added to a review set. For more information, see the Optical character recognition section in this article.

  • After the commit is successfully completed, the value of the status column of on the Collections tab is changed to Committed.

Optical character recognition

When you commit a collection to a review set, optical character recognition (OCR) functionality in Advanced eDiscovery automatically extracts text from images, and includes the image text with the content that's added to a review set. You can view the extracted text in the Text viewer of the selected image file in the review set. This lets you conduct further review and analysis on text in images. OCR is supported for loose files, email attachments, and embedded images. For a list of image file formats that are supported for OCR, see Supported file types in Advanced eDiscovery.

You have to enable OCR functionality for each case that you create in Advanced eDiscovery. For more information, see Configure search and analytics settings.
