And the user will not be able to download the incoming mails.
You may get similar error messages (0x800ccc0d or 0x800ccc0e) while sending emails also.
Causes of Outlook error 0x80004005
Following are some of the leading causes for error code 0x80004005:
- Script Blocking by an antivirus tool
- Missing or Corrupt Registry Keys
- Malicious Attacks
This usually happens due to false identification and reporting by the antivirus software. This is most common with Norton Antivirus. Most antivirus software has a feature known as Script Blocking. If any application on your PC tries to run a script from a .bat or .reg file, the Script Blocking feature becomes active to check for any malicious code in it. If any malicious activity is discovered, then it immediately tries to block the script from executing.
It is often the case that antiviruses falsely detect malicious code in a clean file too (False Positive). In general, your antivirus software might block some scripts run by MS Outlook due to false-positive detection. This will result in MS Outlook throwing the error code 0x80004005.
Registry keys are used to store information and settings for software programs, user preferences, hardware devices, OS configurations, and much more. Any corruption or damage to the keys might affect the proper functioning of MS Outlook, and hence this error.
Any kind of malicious attack on the PST or other Outlook files can be the reason for several abnormal behaviors, including this error.
