๐Ÿ” What is eDiscovery (in Microsoft 365)?

In Microsoft 365eDiscovery is a set of tools that helps you search, preserve, and export content from across Microsoft services like:

  • Outlook (email)

  • Teams

  • OneDrive

  • SharePoint

  • Exchange mailboxes

  • Yammer conversations

It's especially useful for legal investigationsHR inquiries, or compliance audits.


๐Ÿ› ️ Types of eDiscovery in Microsoft 365:

1. Content Search (basic level):

  • Quickly search for emails, documents, chats, etc.

  • Not part of a legal case; used more for internal review or admin tasks.

2. Core eDiscovery:

  • Lets you create cases, assign case members, search for content, place legal holds, and export results.

  • Useful for ongoing investigations or legal requests.

3. Advanced eDiscovery:

  • Adds machine learning, analytics, and filtering.

  • Can reduce data volume and highlight relevant content.

  • Great for bigger or more complex legal cases.

  • Requires Microsoft 365 E5 (or equivalent add-ons).


๐Ÿ›ก️ Key Features:

  • Legal Hold: Freeze content so it can’t be deleted or altered—crucial during lawsuits.

  • Search Query Builder: Filter by keyword, sender, date range, etc.

  • Export Options: Download results for lawyers or investigators.

  • Audit Trail: Keeps track of who searched or accessed what.


๐Ÿง  Real-World Example:

Imagine HR needs to investigate a harassment claim:

  2. Put involved employees’ mailboxes on hold.

  3. Search all messages and files between them.

  4. Export results for legal review.
