What are the causes of error 0x80004005 Operation failed in Outlook

Some of the major causes of MS Outlook error 0x80004005 are listed below:

  • Spyware
  • Virus
  • Registry problems – missing or corrupt registry keys.
  • Script blocking feature enabled when using Norton Antivirus.

This error can prevent you from receiving and sending emails from your Outlook account. Therefore, you need to fix this error because the PST file folder in MS Outlook cannot send and receive emails because of this error.

Usually, it happens due to incorrect identification and reporting of antivirus software. This is the most common case with Norton antivirus.

Most antivirus software has a feature called “script blocking”. When an application on your computer tries to run a script from a .bat or .reg file, the script blocking feature is run to check for malicious code in the file. If malicious activity is detected, an attempt is immediately made to block the script from running.

Usually, antivirus programs incorrectly detect malicious code even in a clean file (false positives). In general, your anti-virus software may block a script running MS Outlook due to a false positive. This causes MS Outlook to generate error code 0x80004005.
