Global Administrator accounts have unrestricted access to all Microsoft 365 services and data. Using them for everyday, non-administrative tasks (such as reading emails, joining meetings, or browsing SharePoint) exposes them unnecessarily to threats like phishing or token theft.
Best practice is to use a standard user account for daily work and only log in with a Global Admin account when administrative tasks are required.
Risk:
If compromised, these accounts give attackers full control over the tenant. Minimizing their exposure is key to reducing your attack surface.
Recommendation:
Avoid using Global Administrator accounts for non-admin tasks. Instead, assign a separate account with minimal permissions for daily use and reserve the Global Admin account for critical admin operations only.
Detection:
This health status becomes critical when a Global Administrator account is assigned a regular user license, like Microsoft 365 Business, E3 / E5 / F3 / F5 / G3 / G5 / A3 / A5, Dynamics, OneDrive for Business, Project, Windows 365 Enterprise licenses.
