Exchange Admin Center Mail-Enabled Security Group Check

Purpose

Document whether SG-Block-Legacy-Auth appeared in Exchange admin center under mail-enabled security groups.

Date captured

2026-06-05 08:06:18

Result

The Exchange admin center Mail-enabled security tab was blank or did not list SG-Block-Legacy-Auth.

Interpretation

SG-Block-Legacy-Auth appears to be an Entra ID security group, not a mail-enabled Exchange security group.

Evidence Value

This confirms that Exchange admin center group evidence and Entra ID group evidence represent different group scopes: - Exchange admin center: Microsoft 365 groups and mail-enabled security/distribution groups - Entra admin center / Microsoft Graph: directory security groups, Microsoft 365 groups, role/security targeting groups
