Exchange_Mailbox WMI class empty

I am trying to setup a script to monitor the size(contents) of specific exchange mailboxes. I found a script that does this using the \\COMPUTERNAME\ROOT\MicrosoftExchangeV2:Exchange_Mailbox Namespace, but when I run a WQL query (Select * From Exchange_Mailbox) to show what is in the class, it just returns nothing!!!

I know WMI is working, because if I run Select * From Exchange_Server I get the list of all servers in the exchange farm.

I THINK this is a problem with exchange. Has anyone else seen this before?

Please See the Following KB as it may resolve your issue:

Why are some of the counters not returning values within my Exchange Server or SQL Server Monitor?

If the KB does not resolve the issue, please see our WMI troubleshooting Guide

Yeah.. I already tried everything in the WMI troubleshooting guide. The weird thing is I can return information from other Classes within the same namespace which is what is making me believe there is a problem that Exchange is not populating the class.

Which version of Exchange are you using?

I would also check to see if maybe Microsoft changed the WMI Class.
