Audit Mailbox Delegation for Retail & E-Commerce
How retail & e-commerce organizations should implement EXT-08 for Microsoft 365 security and compliance.
Retail & E-Commerce organizations face unique security challenges when managing Microsoft 365 environments. The EXT-08 control (Audit Mailbox Delegation) is particularly important for this sector due to pci-dss and soc2 requirements.
Why Retail & E-Commerce Organizations Need This Control
Retail & E-Commerce organizations face specific regulatory requirements including pci-dss, soc2, cis. The EXT-08 control helps address these requirements by:
- SendAs permissions on mailboxes are documented
- SendOnBehalf permissions are tracked
- FullAccess mailbox permissions are reviewed
- Delegation changes are monitored
Mailbox delegation enables users to send email as others or access their mailboxes. Unauthorized delegation can be used for impersonation attacks or to access sensitive communications without detection.
Industry-Specific Considerations
When implementing EXT-08 in a retail & e-commerce environment, consider:
- **Regulatory requirements**: pci-dss, soc2, cis may mandate specific configurations
- **Risk tolerance**: Retail & E-Commerce organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
Implementation Steps
To implement EXT-08 in your Microsoft 365 environment:
- SendAs permissions on mailboxes are documented
- SendOnBehalf permissions are tracked
- FullAccess mailbox permissions are reviewed
- Delegation changes are monitored
This control requires manual implementation through the Entra admin center.
