email network connection failure

When I try to email a purchase order, it comes back with network connection failure. The thing is, I'm on the network, because it's Enterprise, with remote network connections. It has always worked in the past, and even worked this morning once. Any ideas?

Hi there, janai.


Thanks for reaching out to us. I'm here to help resolve this issue so you can email a purchase order successfully. 


Are you using Gmail when sending email for Purchase Order? If so, you can use Secure Webmail for an easier and safer connection to your email provider. You can try setting up Secure Webmail.


Here's how:

  1. From the QuickBooks Edit menu, select Preferences and click Send Forms.
  2. Select Web Mail and click Add.
  3. Select your provider from the drop-down and enter your email address.
  4. Ensure that the Use Enhanced Security checkbox is checked.
  5. Click OK.
  6. When prompted, sign in to your Intuit account. The username or email address you use here may not necessarily be the same as the one you are connecting to QuickBooks.
  7. Your webmail provider's login page will display. Sign in and choose to grant Intuit access. 

For additional reference, you can check this article: Set up email service.


However, if you're using an outlook email let's toggle the settings in the Preferences window. Here's how:

  1. Go back to the Send Forms tab and select QuickBooks Email instead of Web Mail
  2. Click OK.
  3. Close and re-open the Preferences window.
  4. Go back to the  Send Forms tab and change it back to Web Mail

If the issue still persists, I recommend calling our QuickBooks Desktop Support Team. They have additional tools to do a remote session and investigate this further. 

  1. Click this link:
  2. Select the version of QuickBooks, click Contact Us.
  3. Type-in Technical Support on the search bar. 
  4. And click Get the Phone number below.

Please let me know how it goes. I'll be here if you have any questions. Have a good one.

Thank you for the information. I can not get past the add email info with out it stating network error. Please try again later.  I will not pay QB for support, as I pay a year fee for payroll support.  I will scan and email my invoices manually.


Thank you

Hey @WPCladydi,


I appreciate your efforts in trying out the steps provided by my colleague above. Let's try some troubleshooting steps first to isolate the issue.


Some issues arise when your company file is damaged or is not working properly. To ensure that there are no problems with your company file, let's run the Verify & Rebuild Data utilities.


You may follow these steps to run the data utilities:

  1. To Verify Data:
    1. Click on File from the menu bar.
    2. Choose Utilities, then click on Verify Data.
    3. If you see QuickBooks detected no problem with your data, select OK.
    4. If Verify finds an issue with your data, you will be prompted to Rebuild Now or View Errors.
  2. To Rebuild Data:
    1. Click on File from the menu bar.
    2. Choose Utilities, then click on Rebuild Data.
    3. On the QuickBooks Information window, select OK.
    4. If your screen displays QuickBooks is not responding but your cursor is moving, Rebuild is still ongoing.
    5. Select OK when you see Rebuild has completed.

You may refer to this article for more details: Resolve Data Damage on Your Company File.


If you've verified that there's no problem with your company file, but still unable to send emails, you'll need to make sure that you have a strong internet connection.


Fill me in if you have any other questions. I'll be sure to get back to you.

I received the message that Quick Books detected no problems with my data.


This problem just started, I was emailing invoices for years up to Friday 5/10, when I came in on Monday I was unable to do email invoices.  I kept getting a "Quickbooks is unable to send emails due to network connection failure"  Nothing changed from Friday to Monday so I really don't understand what is going on.


Thank you for your time and efforts.

Thank you for getting back to me, @WPCladydi.


There are some reasons why this error occurs. Let me provide some of these and help you further.


Usually, when sending emails in QuickBooks, some errors occur. Some causes of these are:

  • Incorrect email setting
  • Damaged MAPI32.dll file
  • QuickBooks running as administrator
  • Damaged QuickBooks installation
  • Damaged Outlook installation
  • Outlook open in the background when sending email through QuickBooks

To resolve this error, let me help you perform some other troubleshooting steps. First, you'll need to ensure that QuickBooks is not running as administrator. To achieve this, you may follow these steps:

  1. Right-click the QuickBooks icon, then select Properties.
  2. Select the Compatibility tab.
  3. Deselect Run this program as Administrator. But if this option is grayed out, click on Show Settings for All Users.
  4. Select Okay.
  5. Exit, then restart QuickBooks.

Second, you need to ensure that your email preference is set correctly in QuickBooks. Kindly follow these steps:

  1. Click on Edit from the menu tab.
  2. Choose Preferences.
  3. Click on Send Forms from the left panel.
  4. Select on the My Preferences tab.
  5. Toggle the options in the Send e-mail using box, then select QuickBooks E-mail.
  6. Click on OK.
  7. Close QuickBooks and all other programs.
  8. Restart Windows.
  9. Restart QuickBooks.
