Have various Outlook 2016 search problem recently, but couldn't solve the latest one. User is on Windows 7

What happen:

Everytime the user starts the Outlook, it will give this warning.

Search cannot complete the indexing of your Outlook data. Indexing cannot continue for C:\Users\xxxxx\Documents\Outlook Files\xxxxxx.pst (error=0x81404005). If this error continues, contact Microsoft Support.

Search will works, but will not index any new incoming emails

If user close the Outlook and start again, it gives the same warning again, and previous unindex emails will be indexed. But subsequently new incoming emails will not be indexed again until the next Outlook restart.

We have tried:

  1. rebuild the index
  2. create a new mail profile
  3. move the pst to the totally new pst
  4. update Office to latest version 1705, Build 8201.2102
  5. run a repair Office

still having the same problem.

any suggestion?

Update: With the help from Richard Batty here, we located the offending update that causes this problem. On Windows 7, the update is KB4022719, on Windows 10 it's KB4022715.

    How come this search problem only occurs maybe 5% of the time?  Do we know the actually caused it?  When people blame the windows updates, that just doesn't sound right. The updates mentioned in previously as a cause, I don't even have those windows updates I have seen some people have a problem searching, but it doesn't cause errors.  In certain cases re-indexing works and other cases fixing the pst file.  If the fix is come 6-27-15 will everyone get this at the same time?  

    I guess I need to know why certain things happen so I can explain this to others who might have the same problem.  

    Also if someone googles the problem, re-indexing is always the answer.

    The search issue is being tracked in this document (Issue #5), https://support.office.com/en-us/article/Outlook-known-issues-in-the-June-2017-security-updates-3f6dbffd-8505-492d-b19f-b3b89369ed9b?ui=en-US&rs=en-US&ad=US.  Windows will be releasing a Windows Update fix for it on 6/27.  

    There is a workaround in the document to stop Outlook using Windows Search and rather use the legacy built-in search.  Its slower and less feature rich but will work in the interim.  I posted the reg key workaround here if it saves time manually add it in, https://1drv.ms/f/s!AobSYdEz_BdhhrZ0HtSxgApkhHDvEg.  Use Disable key for now and after fix comes out use the Enable key to put it back to Windows Search.
