Missing all files of a folder and the pst file cannot be repaired

Question

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:

Thanks for the update, Hong.
If we copy some emails to TechSupport folder, are those emails still visible in the TechSupportfolder?
Although it doesn't look like a view problem, we may also try to open Outlook with /cleanviews switch to seek our fortune. To do this, exit Outlook, press Windows key + R to open the Run command, type
outlook /cleanviews and press Enter. We may also try to search for the missing emails using Instant Search to see if there is any result.
In addition, we may also try to use the MFCMAPI tool to look into the TechSupport folder and check if we can see and open the missing emails. To do this, please follow the steps below:
1. Download MFCMAPI tool: http://mfcmapi.codeplex.com/
2. Exit Outlook and start MFCMAPI.exe.
3. Click Session > Logon, choose your profile and click
OK.
4. Double-click the PST file that has this issue from the list.
5. In the opened new window, expand Root Container > Top of Outlook data file > Inbox.
6. Find and right-click the TechSupport folder under Inbox, select Open contents table.
7. In the opened new window, check if you can see your emails in the upper portion of the window. If so, double-click an item to see if you can open the email in Outlook window.
Please let me know the result.
