Microsoft 365 Messaging (MS-203)

Kurso aprašymas

Overview

This course examines the key elements of Microsoft 365 messaging administration, including message transport and mail flow, messaging security, hygiene, and compliance, messaging infrastructure, and hybrid messaging. This course is designed for IT Professionals who deploy and manage the messaging infrastructure for Microsoft 365 in their organization.

 

Audience profile

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. 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.
Job role: Administrator
Preparation for exam: MS-203

 

Prerequisites

This course is designed for persons who are aspiring to the Microsoft 365 Messaging Administrator role.

Please note the MS203 is a Microsoft Official Course originally designed for preparation for achieving Microsoft exam certification. Most of the course is focused on Exchange administration (recipients and transport), with only two modules at the end looking at running Exchange in a hybrid model.
If you want detailed understanding of all aspects of Exchange Online Administration it is recommended you attend the Mastering Office 365 Exchange Online Administration course (QAAEXOE) If a learner’s focus is Exchange Hybrid, it is recommended you attend the QA Mastering Exchange Hybrid course (QADEXHE).
