All files under folder Inbox\TechSupport suddenly are missing. The Folder Size window shows this folder has a size of 180719KB.
I used "C:\Program Files\Microsoft Office\Office15\SCANPST.EXE" to try to fix the post files a few times, the problems remains. No matter how many times I run SCANPST.EXT on this pst file, it always find the following error:
Internal errors were found in this file. They must be repaired for this file to work correctly.
Here is the log:
