It was clear from this thread that the moderators didn't have any clue what happened, or how to position this to customers.  The fact of the matter is that emails in the inbox are being deleted despite the fact that no changes were made (such as sweep), no items were ever placed in the delete folder, and the inbox space hadn't been used up.  (I'm assuming an arbitrary folder message limit was implemented in the switch over to outlook.com, which seems to be when these issues started originating)

Then in subsequent threads, I notice the moderators locking every single thread bringing this topic up.
