Audit Mailbox Delegation for Education & Research
How education & research organizations should implement EXT-08 for Microsoft 365 security and compliance.
For education & research companies using Microsoft 365, audit mailbox delegation is a security priority. This guide explains how EXT-08 helps education & research organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Education & Research Organizations Need This Control
Education & Research organizations face specific regulatory requirements including cis, nist-800-53, soc2. 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 education & research environment, consider:
- **Regulatory requirements**: cis, nist-800-53, soc2 may mandate specific configurations
- **Risk tolerance**: Education & Research organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
How to Configure
EXT-08 requires the following configuration:
- SendAs permissions on mailboxes are documented
- SendOnBehalf permissions are tracked
- FullAccess mailbox permissions are reviewed
- Delegation changes are monitored
