    What is Office 365 E-Discovery?

    Microsoft Office 365 e-discovery provides capabilities for the process of identifying, collecting, reviewing and exchanging electronic information for use as evidence in legal cases.

    How does Microsoft 365 E-Discovery work?

    e-Discovery tools in Office 365 enable users to search for content in Exchange Online mailboxes, Office 365 Groups, SharePoint Online, Microsoft Teams, and OneDrive for Business sites as well as Skype for Business conversations.

    There are three solutions in Office 365 e-discovery: 

    — Content search – Enables users to search for content across data sources in Microsoft 365 and export results locally.

    — Core e-discovery – Allows users to create eDiscovery cases and assign managers to them. An expansion of eDiscovery’s basic search and export capabilities, Core lets users place an eDiscovery hold on content locations pertinent to the case.

    — Advanced e-discovery – Enhances the existing case management, preservation, search, and export capabilities available in Core. Provides an end-to-end workflow to help facilitate critical aspects of the eDiscovery process. Advanced eDiscovery lets legal teams manage custodians, collect and copy data from live service into review sets, and filter, search, and tag content to help users identify and focus on only the most relevant content.

    How to simplify Office 365 E-Discovery 

    For legal and IT teams who must manage multiple Office 365 legal hold and e-discovery requests, native Office 365 e-discovery tools for email may not provide sufficient flexibility, granularity or ease of management.

    Email plays a critical evidentiary role in legal proceedings today. As the primary medium for business communication, email can be used to document an individual's knowledge and motivation as well as the timing and intent of actions and business transactions. Many regulatory frameworks have strict guidelines for email retention and e-discovery, and legal teams and IT administrators can easily be overwhelmed with Office 365 e-discovery requests and Office 365 legal hold requirements.

    The right e-discovery tools can help to dramatically reduce the time and resources required to respond to legal and compliance requests. And while the Office 365 e-discovery tools included with the Microsoft platform may be adequate for some companies, many organizations are turning to Office 365 security compliance and archiving solutions from Mimecast to streamline and accelerate Office 365 e-discovery.

    What are the limitations of Office 365 E-Discovery?

    While Office 365 e-discovery offers a broad range of tools, there are a number of limitations that organizations migrating to Office 365 will need to address.

    • The Office 365 Security and Compliance Center, which includes e-discovery and preservation policies, does not provide uniform tools across all subscriptions.
    • Organizations that want to deploy enterprise-wide litigation holds may be frustrated by restrictions that Office 365 places on litigation hold features for end-user mailboxes.
    • Performance can be limited in Office 365 e-discovery – some users have experienced slow results or variations in the accuracy of searches.
    • In the basic subscription, Office 365 e-discovery performs searches without analysis capabilities, which can result in search results with duplicate files, unindexed items and potential false positives. This excess in data can add significant costs for third-party review services.
    • Office 365 Advanced e-discovery can’t match the robust functionality of third-party review tools, particularly for processing and review.
    • Leveraging advanced functionality can be complicated and may require companies to hire an in-house analyst or counsel.

    How to address the gaps in Office 365 E-Discovery?

    Most organizations will need to augment Office 365 with additional solutions for e-discovery that can manage outside data sources and provide additional functionality. To complement the abilities of Office 365 e-discovery, organizations should look for solutions that offer:

    • A cloud SaaS solution that can scale easily as needed while reducing operational and capital costs.
    • An archive that provides a single repository for archived and live email that enables comprehensive e-discovery across mobile and stationary devices.
    • Litigation holds that can be deployed rapidly and managed centrally.
    • Comprehensive data retention policies with in-depth control over data purge requests by clients to satisfy GDPR and other regulatory requirements.
    • Easy-to-use tools and self-service options that simplify e-discovery, legal and compliance efforts.
