Quick tip for Enabling a Mailbox for a user already active in Active Directory.
Launch the Exchange Management Shell (EMS) and run the following command:
- Enable-Mailbox -Identity UserName
![Exchange 2019 - create a new mailbox with powershell Exchange 2019 - create a new mailbox with powershell](https://everything-powershell.com/wp-content/uploads/2018/12/mbx1.png)
Once it runs you will see the info below the command as shown above, to check the mailbox you can run the following command:
- Get-Mailbox
![Exchange 2019 - create a new mailbox with powershell Exchange 2019 - create a new mailbox with powershell](https://everything-powershell.com/wp-content/uploads/2018/12/mbx2.png)
As we can now see, the new mailbox is showing under the list of mailboxes.
Hope it helps.
