Microsoft 365 Messaging Administrators deploy, configure, manage, and monitor messaging infrastructure, permissions, client access, mail protection, and mail flow in both on-premises, hybrid, and cloud enterprise environments.
Pass the following two exams.
While it's not a strict prerequisite, it is recommended that you earn your Microsoft 365 Fundamentals certification prior to training for other Microsoft 365 certifications.
Microsoft provides two re-certification options for those who want to demonstrate continuous competence in these areas. You can demonstrate that you're staying current in the technology by either taking a re-certification exam or stay-current course within two years of earning your certification. As soon as you pass either the course or the exam, the expiration date on your certification will be extended two years from that date.
The Messaging Administrator deploys, configures, manages, and troubleshoots recipients, permissions, mail protection, mail flow, and public folders in both on-premises and cloud enterprise environments. Responsibilities include managing message hygiene, messaging infrastructure, and hybrid configuration and migration. The Messaging Administrator also implements and manages disaster recovery, high availability, and client access. To implement a 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 applications.
