Troubleshooting steps to fix ‘scanpst.exe fails with Fatal Error 80040818’

Outlook PST powers the smooth functioning of Outlook by acting as a safe-house for all emails, contacts, calendar entries, notes, etc. associated with user mailboxes. However, with time and continued usage, data keeps piling up within PST files pushing them towards size limit breach and eventual corruption. The ScanPST.exe utility offered by Microsoft comes handy to detect and fix errors and corruption within PST files. While it works in most situations, sometimes it can fail due to several reasons and throw cryptic errors like the ‘Fatal Error 80040818’ leaving users confused and clueless as to what should be done next.



Read on to find out everything there is to know about this error and how you can fix it without much trouble.



Causes that trigger ‘Fatal Error 80040818’



Outlook supports PST files of two formats – ANSI and Unicode. Outlook versions 2002 and earlier supported ANSI format PST files which were bound by a 2GB size limit. This limit was extended to 20GB for Unicode format PST files supported by Outlook versions 2003 and beyond. The amount of data that your Outlook PST can handle therefore depends on the format in which it is encoded. Whenever the size of the PST file approaches its limit, it starts facing the threat of corruption.



Other causes of PST file corruption include:



  • Accessing ANSI format PST file with Outlook 2003 or later versions
  • Over-stuffing PST files with data without cleaning or archiving them once a while
  • Abrupt system termination or Frequent Power surges
  • Virus infection to the files
  • Bad sectors on the hard drive where the PST is saved

If your Outlook PST file has been corrupted owing to any of the above mentioned reasons, you are bound to face problems. Resolving them at the earliest is the only way to get back to work.

Excel files reporting “someone else is working in file” when trying to save to network share

I need a solution

I’ve been encountering an issue with Windows 10 clients using Office 2016 Excel to open/edit/save Excel files to a network share.

We are running a mix of SEP 14.0.3752-14.0.3876 clients, managed by SEPM 14.0.3876. Our file server is Windows Server 2016. Our clients are Windows 10, builds 1607, 1703, and 1709.

What happens in that a user opens the Excel file, makes edits, goes to save, and gets an error that the file is being worked on by another user and cannot be saved (which is not the case). A ######.tmp files gets created on the share (which is normal when an Excel file is saved), but this file should disappear during a proper save. Instead, the ######.tmp file remains, so Excel thinks that the Excel file is in use and fails to save.

The real kicker here is that it happens randomly across various users having the issue, and from one day to the next, I might not see it on the same client working on Excel files on the same share. And I cannot duplicate the error when I try. It is maddening!

Why am I posting this in a Symantec Forum? Because I have tried various workarounds on the Windows side with no luck, but the constant in all this is that SEP is running on my Windows 10 clients (and Windows Server clients). I even removed SEP from the file server hosting the share, leaving only the Windows 10 clients running SEP, but I am still seeing the issue.

Any thoughts? Perhaps SEP is running some sort of scan that is causing the locking, but if that were the case, wouldn’t I see this on all my clients accessing the multiple shares on my servers?

Could you please confirm if this is working as designed? Is the tag just described that the emails have ever been uploaded to ICN successfully? Even if after upload, the document was deleted.
