Exchange Server/Servers and databases

Overview

This article describes how to manage the Exchange Server itself and the database.

Typically, you don't need to change these settings for Exchange Server and the database.

Prerequisites

The account used to operate must have appropriate roles to manage the server.

Manage a server

Log in to the Exchange Admin Center and navigate to servers → servers.

Select a server and click Edit(✏️).

General settings

You can enter the product key to license this server on this page.

You can also change the product key to upgrade the server.
