Detailed technical explanation
How to think about this question
The Microsoft 365 E5 Compliance add-on enables features like predictive coding (using machine learning to prioritize review), legal hold (preserving content in-place via eDiscovery cases), and retention policies that can be set for up to 10 years using Preservation Lock. Under the hood, these rely on the Microsoft Purview compliance portal and Exchange Online's litigation hold, which can apply to mailboxes, SharePoint sites, and Teams data. In a real-world scenario, a company under regulatory scrutiny (e.g., SEC or FINRA) would use this add-on to meet retention mandates without migrating to a full E5 license.
