Original title: Subfolders gone from WLM but still there in Outlook

Today all of the subfolders disappeared from WLM. There is no little  triangle indicating subfolders.  I have Win 8.1 with autoupdate.  The Inbox is current but no subfolders.  Other folders do not have their subfolders either. Compact view seems to only toggle on and off.   The  Recovered folder in storage does not have any of the subfolders. I closed and opened WLM but does not help.

Outlook does have all the subfolders. but I do not like working in Outlook.
