Back in September, I posted on using Powershell Community Extensions to manage MSMQ queues. Community Extensions are cool in how they provide you with simple comandlets to get and create the queues but they lack advanced features that native System.Messaging.MessageQueue class posesses. Here's an example of managing MSMQ queues using System.Messaging from Powershell, complete with queue listing, checking for existance, deleting, creating, and setting permissions. This works on Powershell 1.0 and does not require the Community Extensions installed. As always, make sure you have enabled script execution (set-executionpolicy unrestricted). Enjoy!
