Causes of Outlook Error: Not Implemented

Several prominent factors contribute to the occurrence of this error:

  • Antivirus Application
  • The ‘Not implemented’ error can be triggered by antivirus applications that scan emails before sending or receiving them. This process can lead to issues with the send/receive functionality, causing the error to occur.

  • Installed Add-in in Outlook
  • Another potential cause of the error is the presence of Outlook add-ins or plug-ins that interfere with the normal performance and functioning of Outlook.

  • Outlook Send/Receive Settings file damaged
  • The error may also arise when the send or receive settings are dysfunctional, often as a result of damage to the settings file.

  • MS Outlook not installed properly
  • The ‘Not Implemented’ error might occur if you have two different versions of MS Outlook installed on your system simultaneously.
