Which command is used to create a new mailbox in Exchange using PowerShell?

The command used to create a new mailbox in Exchange using PowerShell is New-Mailbox. This cmdlet is specifically designed for the purpose of creating mailboxes for users in an Exchange environment. When you run this command, it allows you to specify various parameters, such as the user's name, email address, and other mailbox-related settings, which facilitates the setup of a new mailbox.

Other options are not applicable for creating new mailboxes. For instance, Create-Mailbox is not a valid cmdlet in Exchange PowerShell; therefore, it cannot be used. Add-Mailbox is also not a recognized cmdlet as it does not exist in PowerShell for mailbox management, making it ineffective for this purpose. Set-Mailbox is utilized for modifying existing mailbox properties rather than creating new mailboxes. Understanding the specific functions of these cmdlets is crucial for effective mailbox management in Exchange.
