troubleshoots recipients, permissions, mail protection, mail flow, and
public folders in both on-premises and cloud enterprise environments.

secure hybrid topology that meets the business needs of a modern
organization, the Messaging Administrator must collaborate with the
Security Administrator and Microsoft 365 Enterprise Administrator. The
Messaging Administrator should have a working knowledge of
authentication types, licensing, and integration with Microsoft 365
