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.

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.

After delete the email document from ICN, the “uploaded successfully” tab was still in Outlook.

The end User select the email message on outlook and add/upload to ICN repository with entry template. Added document can be found in the repository. Email message on outlook have a tag for “Uploaded successfully”.

User delete the email message in the repository. But when user checks back the MS Outlook message. The indicative tag is still showing on the message.

As shown below, those emails uploaded to DMS will have the orange toggle indicator whereas when the email was deleted in DMS, the indicator is not removed.

![alt text][1]

CPE and CEC version 5.2.1.7; ICN version 3.0.1; Navigator for office plugin 3.0.1

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.

Batches being created and shown in monitor on tmweb.net, but not in the batches folder. All aborting.

I have an application that is working perfectly via vScan, but we are adding IMAP email functionality. I set up the workflow, created the ruleset, rules and task profiles that I needed, and set up a rulerunner thread to process the incoming emails.

When rulerunner starts batches start showing up in the tmweb.net monitor (all aborted), and no batch folders or files are created. In the tmweb.net workflow settings for my EmailScan task, the mode is Batch creation and the program is set to VScancl.aspx. I have tried setting the program value to RuleRunner as well with the same results.

Unless I missed something, the documentation is lacking the key setup information outside of the actual Ruleset/Rule info.

Any thoughts or suggestions are welcome.
