A deployment is using an external third party mail gateway, and this has mandated the creation of a user mailbox within their instance of Exchange 2016 Standard, to serve as a journaling mailbox for internal e-mails.
This is all fine conceptually, but the internal mailbox is not emptying when it passes the e-mails over to the third party gateway for logging, and it has somehow grown to approximately 250GB in size, which is obviously causing problems for the server.
Given its size, I cannot readily see how I could issue a command to purge the contents of this mailbox's inbox other than via the Exchange Management Shell, and so I was wondering if anybody here knows how to permanently delete the contents of a user's inbox via the Exchange Management Shell and, if so, how you would go about doing it.
Thanks so much for your time in advance, and I hope you are all keeping safe and well :)
