Moving 350,000 EMails with a specific subject from FolderA to FolderB

I have a folder by name FolderA. I have some 350,000 EMails with the subject: “Splunk has been disabled”. I also have another about 45,000 EMails in FolderA which have other subjects. How can I move all the 350,000 EMails with the subject: “Splunk has been disabled” from FolderA to FolderB ? I need to ensure that only these 350,000 EMails move from FolderA to FolderB, and that the other 45,000 EMails remain in FolderA.

Can someone let me know how to implement a policy or a Rule to get this done ? This is in Microsoft Outlook.
