Dismount-Database wierd exception
From the Exchange Management Shell, I can execute the following command: Dismount-Database -Identity "Mailbox Database" If I then follow this with: Get-MailboxDatabase -Identity "Mailbox Database" -Status The "Mounted" field contains "False". Using a managed C++ program I can execute any Exchange Server command from the "Microsoft.Exchange.Management.PowerShell.Admin"snapins using RunspaceInvoke->Invoke("Command"). However, if I try to run the Dismount-Database, an exception is thrown with the following message: "System.Management.Automation.CmdletInvocationException: Cannot invoke this function because the current host does not implement it.at System.Management.Automation.Internal.Host.InternalHostRawUserInterface.ThrowNotIntercative()at System.Management.Automation.Internal.Host.InternalHostUserInterface.PromptForChoice(String caption, String message, Collect" Clearly, this command is looking for the interactive reply of "Y" however, theDismount-Database command interface does not support a "-Force" option. Is there a way to format this command such that the RunspaceInvoke will execute it properly?

After many days of searching, I found an article that shows that the solution is as follows: Dismount-Database -Identity "Mailbox Database" -Confirm:$false How the author of this fix located the information in the documentation is beyond me. I've looked and looked.

I ran into the same problem with Move-StorageGroupPath cmdlet. This one includes a "Force" parameter which didnt seem to work,but after alot of fooling around I found I needed this "Confirm" parameter also when using RunSpaceInvoke. Thanks for posting your solution.

Thanks for your posting Fletcher. That was really helpful while I was doing the same thing with Powershell.
