Create Mailbox User using Powershell

by
Creating new mailbox user is one of the important task for every Administrator either for actual new employee or for internal testing. You can use Exchange Management console to create new mailbox user, but it is a time consuming job if you want to create multiple AD users (bulk mailbox users). To overcome this, we can use Powershell Script to Create new AD User with mailbox.

Before proceed, run the following command to enable Exchange cmdlets if you are working with Powershell console instead of Exchange Management Shell.

Add-PSSnapin *Exchange*

Summary

Create New Mailbox User

We can use the Exchange Management Powershell cmdlet New-Mailbox to create new mailbox AD user. The following command creates the Active Directory user “Will Smith” in the TestOU, with a mailbox on the TestDBStore database.

New-Mailbox -UserPrincipalName [email protected] -Alias 'WillSmith' -Database 'TestDBStore' -Name WillSmith –OrganizationalUnit TestOU -Password (ConvertTo-SecureString 'MyPassword123' -AsPlainText -Force) -FirstName Will -LastName Smith -DisplayName 'Will Smith' -ResetPasswordOnNextLogon $True

Enable Mailbox for existing AD User

We can create a mailbox for an existing Active Directory user using exchange powershell cmdlet Enable-Mailbox. The following powershell command creates mailbox for the existing AD user “Chris Jordan”.

Enable-Mailbox -Identity:'ChrisJordan' -Alias:'ChrisJordan' -Database: 'TestDBStore'
