Import Non-Office 365 Content for Advanced eDiscovery Analysis

Microsoft 365 in 365 blog series


What It Is:

Office 365 Advanced eDiscovery uses machine-learning and predictive analytics to refine and de-duplicate the data subset for review, allowing you to focus your eDiscovery efforts on the most relevant content, whether from within Office 365 (Exchange Online, SharePoint Online, OneDrive for Business, Skype for Business, Office 365 Groups, and Microsoft Teams) or outside, via the new import utility. Why is this important? If you’ve ever participated in a large eDiscovery effort, you know that maintaining parallel analysis effort across data that should be in a single case, but comes from separate sources, adds additional complexity and risk (and time) to the process. By allowing users to import non-Office 365 data into a single location, teams can move a copy of their imported data to an Azure container and analyze *everything* that is relevant using Office 365 Advanced eDiscovery.

With Advanced eDiscovery, you can better understand your Office 365 data and reduce your eDiscovery costs. Advanced eDiscovery helps you analyze unstructured data within Office 365, perform more efficient document review, and make decisions to reduce data for eDiscovery. You can work with data stored in Exchange Online, SharePoint Online, OneDrive for Business, Skype for Business, Office 365 Groups, and Microsoft Teams. You can perform an eDiscovery search in the Office 365 Security & Compliance Center to search for content in groups, individual mailboxes and sites, and then analyze the search results with Advanced eDiscovery.

Not all documents that you may need to analyze with Office 365 Advanced eDiscovery will live in Office 365. With the Non-Office 365 content import feature in Advanced eDiscovery you can upload documents that don’t live in Office 365 (except PST files) into a case linked, Azure storage blob and analyze them with Advanced eDiscovery. This procedure shows you how to bring your non-Office 365 documents into Advanced eDiscovery for analysis. [Read More]

You can use the Content Search eDiscovery tool in the Office 365 Security & Compliance Center to search for items that were imported to mailboxes in Office 365 from a third-party data source. You can create a query to search all imported third-party data items or you can create a query to only search specific third-party data items. Additionally, you can also create a query-based Preservation Policy or a query-based eDiscovery hold to preserve third-party data in Office 365.

Post from Alym Rayani, director, Office 365 security & compliance team

While the amount of data being generated and stored in Office 365 is growing at an exponential rate, many organizations still have data in legacy file shares and archives. Data is also being generated in other cloud services which may be relevant for an eDiscovery case surrounding a Data Subject Request. Analysis of non-Office 365 data allows organizations to import the case-specific copy of such data into a specifically assigned Azure container and analyze it using Office 365 Advanced eDiscovery. Having one eDiscovery workflow for both Office 365 and non-Office 365 data provides organizations with the consistency they need to make defensible decisions across the entire data set of a case.

This feature is currently in preview and requires an Advanced eDiscovery license for each user whose data is being analyzed. Later this year, in addition to Advanced eDiscovery licenses this feature will require the purchase of the eDiscovery Storage plan for all non-Office 365 data imported into the specifically assigned Azure container for analysis by Advanced eDiscovery. The eDiscovery Storage plan comes in increments of 500GB of storage and is priced at $100 per month. [Read More]
