Create a draft collection in Advanced eDiscovery
After you've identified custodians and any non-custodian data sources for the case, you're ready to identify and locate a set of documents that are relevant. You do this by using the Collections tool to search data sources for relevant content. You do this by creating a collection that searches specified data sources for content that matches your search criteria. You have the option to create a draft collection, which is an estimate of the items are found or you can create a collection that automatically adds the items to a review set. When you create a draft collection, you can views information about the estimated results that matched the search query, such as the total number and size of items found, the different data sources where they were found, and statistics about the search query. You can also preview a sample of items that were returned by the collection. Using these statistics, you can change the search query and rerun the draft collection to narrow your results. Once you're satisfied with the collection results, you can commit the collection to a review set. When you commit a draft collection, the items returned by the collection are added to a review set for review, analysis, and export.
Before you create a draft collection
Add custodians and non-custodial data sources to the case before you create a draft collection. This is required so that you can select the data sources when you create a draft collection. For more information, see:
You can search additional data sources (ones that haven't been added to the case as custodial or non-custodial locations) in a draft collection for content that may be relevant to the case. These data sources might include mailboxes, SharePoint sites, and Teams. If this situation is applicable to your case, compile a list of these data sources so you can add them to the collection.
Create a draft collection
In the Microsoft 365 compliance center, open the Advanced eDiscovery case, and then select the Collections tab.
On the Collections page, select New collection > Standard collection.
Type a name (required) and description (optional) for the collection. After the collection is created, you can't change the name, but you can modify the description.
On the Custodial data sources page, do one of the following things to identify the custodial data sources to collect content from:
Click Select custodians to search specific custodians that were added to the case. If you use this option, a list of the case custodians is displayed. Select one or more custodians. After you select and add the custodians, you can also select the specific data sources to search for each custodian. These data sources that are displayed were specified when the custodian was added to the case.
Click the Select all toggle to search all custodians that were added to the case. When you select this option, all data sources for all custodians are searched.
On the Non-custodial data sources page, do one of the following things to identify the non-custodial data sources to collect content from:
Click Select non-custodial data sources to select specific non-custodial data sources that were added to the case. If you use this option, a list of data sources displayed. Select one or more of these data sources.
Click the Select all toggle to select all non-custodial data sources that were added to the case.
On the Additional data sources page, you can select other mailboxes and sites to search as part of the collection. These types of data sources weren't added as custodial or non-custodial data locations in the case. You also have two options when searching additional data sources:
To search all content locations for a specific service (Exchange mailboxes, SharePoint and OneDrive sites, or Exchange public folders), click the corresponding Select all toggle in the Status column. This option will search all content locations in the selected service.
To search specific content location for a service, click the corresponding Select all toggle in the Status column, and then click Users, groups or teams (for Exchange mailboxes) or Choose sites for (SharePoint and OneDrive sites) to search specific content locations.
On the Conditions page, you can create the search query that is used to collect items from the data sources that you've identified in the previous wizard pages. You can search for keywords, property:value pairs, or use a keyword list. You can also add various search conditions to narrow the scope of the collection. For more information, see Build search queries for collections.
On the Save as draft or add to review set page, select Save collection as draft.
The other option on this page lets you collect items and add them direct to a review set. Instead of creating a draft collection that you can review statistics for and preview a sample of the collection results, this option skips that process and automatically adds the collection to a review set. If you select the second option to add the collection to a review set, you have additional settings to configure, such as collecting entire chat conversation threads in Microsoft Teams and Yammer and collecting cloud attachments (also called modern attachments). For more information about these settings, see Commit a draft collection to a review set.
On the Review your collection page, you can review and update the collection settings that you configured on the previous pages.
Summary tab: Review and modify the name and description of the collection, the collection search criteria, additional data locations, and the collection type.
Sources tab: Review and modify the custodial and non-custodial data sources for the collection.
Click Submit to create the draft collection. A page is displayed confirming that the collection was created.
What happens after you create a draft collection
After you create a draft collection, it listed on the Collections page in the case and the status shows that it's in progress. A job named Preparing search preview and estimates is also created and displayed on the Jobs page in the case.
During the draft collection process, Advanced eDiscovery performs a search estimate using the search criteria and data sources that you specified in the collection. Advanced eDiscovery also prepares a sampling of items that you can preview. When the collection is complete, the following columns and corresponding values on the Collection page are updated:
Status: Indicates the status and type of collection. A value of Estimated indicates that a draft collection is complete. This same value also indicates that the collection is a draft collection, and that it hasn't been added to a review set. A value of Committed in the Status column indicates that the collection has been added to a review set.
Estimate status: Indicates the status of the estimated search results and whether or not the search estimates and statistics are ready for review. A value of Successful indicates the results of the draft collection are ready for review. After you first submit a draft collection, a value of In progress is displayed to indicate the collection is still running
Preview status: Indicates the status of the sample items that you can preview. A value of Successful indicates the items are ready for preview. After you first submit a draft collection, a value of In progress is displayed to indicate that the collection is still running.
Next steps after a draft collection is complete
After the draft collection is successfully completed, you can perform various tasks. To perform most of these tasks, just go the Collections tab and click the name of the draft collection to display the flyout page.
Here's a list of things you can do from the collection flyout page:
Select the Summary tab to view summary information about the collection and the estimated search results returned by the collection. This includes that total number of items and size of the estimated search results, the number of mailboxes and sites contained search results, and the search conditions (if used) used to scope the collection.
Select the Data sources tab to view a list of custodians and non-custodial data sources) that were searched in the collection. Any additional content locations that were search are listed under Locations on the Summary tab.
Select the Search statistics tab to view statistics about the collection. This includes the total number and size of items found in each service (for example, Exchange mailboxes or SharePoint sites) and a condition report that displays statistics about the number of items returned by different components of the search query used by the collection. For more information, see Collection statistics and reports.
Click Review sample (located at the bottom of the flyout page) to preview a sample of the items returned by the collection.
Commit the draft collection to a review set (by clicking Actions > Edit collection). This means that you rerun the collection (using the current settings) and add the items returned by the collection to a review set. As previously explained, you can also configure additional settings (such as conversation threading and cloud-based attachments) when you add the collection to a review set. For more information and step-by-step instructions, see Commit a draft collection to a review set.
Manage a draft collection
You can use the options in the Actions menu on the flyout page of a draft collection to perform various management tasks.
Here's are descriptions of the management options.
Edit collection: Change the settings of the draft collection. After you make changes, you can rerun the collection and update the search estimates and statistics. As previously explained, you use this option to commit a draft collection to a review set.
Delete collection: Delete a draft collection. Note that after a draft collection is committed to a review set, it can't be deleted.
Refresh estimates: Rerun the query (against the data sources) specified in the draft collection to update the search estimates and statistics.
Export as report: Exports information about the draft collection to a CSV file that you can download to your local computer. The export report contains the following information:
The identity of each content location that contains items that match the search query in the draft collection. These locations are typically mailboxes or sites.
The total number of items in each content location.
The total size (in bytes) of the items in each content location.
The service (such as Exchange or SharePoint) in which the content location is located.
Copy collection: Create a new draft collection by copying the settings from an existing collection. You have to use a different name for the new collection. You also have the option to modify the settings before you submit the new collection. After you submit it, the search query is run and new estimates and statistics are generated. The is a good way to quickly create additional draft collection and then modify selected settings as necessary while still preserving information in the original collection. This also lets you easily compare the results of two similar collections.
After a draft collection is committed to a review set, you can only copy the collection and export a report.
