Microsoft 365 Certified Messaging Administrator Associate (1 科 Exchange Online，採用 Exchange Server 2019 技術) 國際認可證書課程

由於電子訊息系統能為公司快速及以低成本傳遞資料，再加上公司對重要訊息有需要作出直接的管理及對訊息系統有需要作出符合公司運作的特別設定，故此有很多公司，不論大、中或小型，都紛紛為公司建立訊息系統，以致 Microsoft 的訊息系統 Exchange Server 及 Exchange Online 大受歡迎，形成市場對擁有 Microsoft 365 Certified Messaging Administrator Associate 認證人材的強大需求，所以他們的市場價值亦相對其他行業為高。

根據英國權威市場調查機構 The Radicati Group 於 2020 年發表市場調查報告 “Microsoft Office 365, Exchange Server and Outlook Market Analysis, 2020 - 2024”，該報告指出 Exchange Online 於訊息系統的市場佔有率高於 57%，並預測其市場佔有率會持續上升，該報告也被著名網站 Yahoo! Finance 刊登。而 Exchange Online 更被該報告稱為 “企業訊息傳遞和協作市場的市場領導者”。

Microsoft 已經成為雲端通訊市場的領導者，並於全球範圍內，共有 2億5千8百萬工作人口使用 Microsoft 365 提供的雲端通訊服務。(資料來源：MSFT FY20 Q3 財務報告；Microsoft 365, 前稱Office 365, 的所有付費計劃都已包含 Exchange Online 雲端通訊服務)

其餘的 1 億工作人口仍然在使用由企業自行建立，維護及擁有的 Microsoft Exchange Server On-Premises (資料來源 --- Survey Analysis: Microsoft Dominates Cloud Email in Large Public Companies but Shares the Rest With Google)。
