    Hm, I tested only against Exchange Online, so it might be a cloud-only thing 😕

    [18:23:41][O365]# Get-MailboxFolderStatistics vasil -FolderScope Inbox | select *ItemsInFolder*

    VisibleItemsInFolder : 6615
    HiddenItemsInFolder : 150
    ItemsInFolder : 6765
    DeletedItemsInFolder : 0
    ItemsInFolderAndSubfolders : 6777
    DeletedItemsInFolderAndSubfolders : 0
