When I command: Get-MailboxDatabase -Status -Identity mailboxname the "Mounted" field contains true or false. If I do the same thing from RunspaceInvoke, the "Mounted" field contains no data. Why is this different between the PowerShell and RunspaceInvoke?

The solution to this was a matter of users. In the RunspaceInvoke context, I was not the user that was permitted to administer the Exchange Server.

What permission do I need to view the Mounted status.Currently I can see the Mounted status in the Exchange Mgt. Console but NOT in the Exchange Management Shell nor in the RunspaceInvoke (C#) context.Thanks in advance,Matt

Nevermind, stupid me forgot to add the "-status" flag which is also in your thread title so that makes me double stupid.
