Assume that you export a mailbox into a personal folder (.pst) file by using the new-mailboxexportrequestcmdlet in a Microsoft Exchange Server 2013 environment. There are subfolders in the “Deleted Items” folder of that mailbox. In this situation, the subfolders are not visible in the .pst file in Microsoft Outlook. You can verify this issue by creating a new subfolder that has the same name as the invisible folder. However, this operation cannot be completed.
