(Updated) Microsoft Purview eDiscovery: Naming and description fields will restrict certain special characters

🚨 The Signal: Microsoft Purview eDiscovery will restrict special characters (+, =, @, /, *) in naming and description fields for new or edited cases, holds, searches, and review sets. This hardens input validation, improving service resilience.

The Impact

eDiscovery administrators are affected by new character restrictions, reducing the risk of malicious input and improving service stability.

• eDiscovery administrators: Must adapt naming conventions for new/edited entities.
• Security teams: Benefit from enhanced input validation and reduced attack surface.
• Compliance officers: Gain improved assurance of eDiscovery data integrity.

The Action

1. Review existing eDiscovery naming conventions for cases, holds, searches, and review sets.
2. Communicate the restricted characters (+, =, @, /, *) to eDiscovery administrators.
3. Update internal documentation for eDiscovery procedures to reflect new character limitations.
