"Delivery Error: Delivery Server Down" is an error message that can happen in QuickBooks, especially when trying to send emails from within the QuickBooks application. This error message indicates that QuickBooks is unable to communicate with the server responsible for sending out emails, which could be due to a temporary server outage, network issues, or misconfigured email settings.

Worried about How to fix delivery error: delivery server down QuickBooks error? Here are some steps to troubleshoot QuickBooks delivery server down issue.


  1. Check Internet Connection: Ensure that your computer has a stable and active internet connection. A poor or unstable connection can stop QuickBooks from communicating with the email server.
  2. Check Email Server Status: Sometimes, the email server being used by QuickBooks might experience temporary outages. Check the status of the email server provided by your email service provider to see if there are any ongoing issues.
  3. Restart QuickBooks: Close and reopen QuickBooks to see if the issue continuous. A simple restart might help resolve the communication problem.
  4. Check Email Settings in QuickBooks:
  • Open QuickBooks and go to the "Edit" menu, then select "Preferences."
  • Choose "Send Forms" from the left sidebar.
  • In the "My Preferences" tab, make sure that the email account you're using is selected and configured accurately.
  • Check the SMTP (outgoing mail) settings, including the server name, port, and security settings. Make sure they match your email provider's recommendations.
  • If you're using Gmail, Yahoo, or another popular email provider, you might need to use their specific settings for sending emails through third-party applications.
  1. Firewall and Antivirus Settings: Sometimes, security software or firewalls on your computer might block QuickBooks' communication with the email server. Temporarily disable your firewall or antivirus software and see if you can send emails from QuickBooks. If it works, you might need to adjust the settings of your security software to allow QuickBooks access.
  2. Update QuickBooks: Ensure that you're using the latest version of QuickBooks. Updates repeatedly include bug fixes and improvements that can address communication issues.
  3. Contact QuickBooks Support: If you've tried the above steps and the issue still continues, it's recommended to reach out to QuickBooks customer support. They can provide specific guidance based on your setup and help you troubleshoot the issue further.

Remember to be cautious when making changes to email and security settings, as incorrect configurations could potentially cause other issues. If you're unsure about any step, consider seeking assistance from a technical expert or IT professional.
