How to Fix Outlook Error: Object not found

Outlook Send Error: “The operation failed. An object could not be found” or “Object not found”

Description: the “object not found” error message is triggered when you are trying to send an email from Outlook. The regular reasons are:

  • Your Outlook profile is corrupt
    Solution: go to the Windows Control Panel -> Mail -> Mail Setup -> Show Profiles -> Add. Create a new Outlook profile, add your email account(s) to it, open Outlook with your new profile and try sending the message again.
  • Your automatic SMTP settings are not picked up correctly
    Solution: manually configure your outgoing SMTP server settings in Outlook. The easiest way to do it is by removing your email account (from the Outlook file menu -> Account Settings) and adding it again (this time make sure you do not use the option to auto-detect mail server settings). If you are unsure about the SMTP values, please contact your email provider.
