Exchange PowerShell script to search a mailbox based on Message Class

Scenario:  You want to search a mailbox via PowerShell for any messages of a specific message class.

The link below contains a script that can be downloaded. I ran it from PowerShell to look for a CommVault message class (IPM.Note.Commvault.Galaxy.Stub) that would show if we have any stubbed messages in a users mailbox with success. Note: I had to change the location of the webservices.dll in the script.

.\Search-MailboxForMessageClass.ps1 IPM.Note.Commvault.Galaxy.STub

PowerShell: Search mailbox for items of a particular message class (ItemClass)
