How do you create a new mailbox in Exchange Server?

Creating a new mailbox in Exchange Server can be achieved through several methods, but using the Exchange Admin Center or the PowerShell cmdlet New-Mailbox is the most direct and widely accepted approach.

The Exchange Admin Center provides a graphical interface that simplifies the process for administrators who may prefer not to use command-line tools. It allows users to fill in necessary fields such as user information, mailbox type, and storage settings in an intuitive manner.

On the other hand, the New-Mailbox PowerShell cmdlet is a powerful scriptable option that enables administrators to create mailboxes programmatically. This is especially useful for bulk operations or when automation is required, as it can be included in larger scripts or scripts that manage multiple mailbox creation tasks.

This answer highlights not just the correct method but also appreciates the flexibility Exchange provides through its graphical and command-line interfaces, illustrating best practices among Exchange administrators. Other options presented are less relevant as they either involve commands that do not exist or pertain to different functionalities within Exchange that are not specifically aimed at creating mailboxes.
