Question

Quickbooks is unable to send emails due to network connection failure

I have been trying and failing to send my PO through quickbooks to a vendor the last couple days. I get the "Quickbooks is unable to send emails due to network connection failure." error message. I have updated windows on my server, I have updated quickbooks, I have deleted my email address from the send forms tab in preferences and re-inputted my email, I have switched from the quickbooks emails and clicked ok - just to go back to the regular email, I verified the file, rebuilt the file and none of this has worked. 

 

The vendor I was trying to send the PO to has two different names, separated by a semi-colon, in the "To:" box. As a last ditch attempt to do something, I deleted one of the names from the box. It worked. Can someone help me as to why this is happening all of a sudden?

Good morning, @gary5077

 

Thanks for coming to the Community with your question about sending emails through your QuickBooks Desktop account. 

 

QuickBooks requires recipients to be separated by a comma and a space, rather then a semicolon. This may be way you were able to send the email until after deleting the semicolon plus the other name. 

 

I recommend trying this method to see if it works for you. 

 

I hope this helps. Feel free to come back if you have any other questions or concerns. Have a splendid day!

Here's how to reach them:

 

  1. Open QuickBooks.
  2. Go to Help, then select QuickBooks Desktop Help.
  3. Select Contact Us.
  4. Give a brief description of your issue, then select Let's talk, and then choose a way to connect. Phone support may be limited due to volume.

Finally, I just discovered the solution too....I deleted the second email in the To line that was separated by a semicolon....it used to work that way in old versions I think. Anyway, I just added the persons email to the CC section and it sent. Nice to know that you can put more than one person in the "To" field separated by a comma and a space.  Problem solved. However, it should not send up a "network connection error".....

Great to hear it's working, @glaciator.

 

I'm here to ensure that you won't encounter the "network connection error". Some of the possible reasons for connection error are the following:

 

  • Windows firewall and other internet settings are blocking the QuickBooks file to access the required ports.
  • The Network Descriptor (ND) file is missing or corrupted.
  • The hosting computer is in standby or hibernation mode. This may interrupt your connection due to which you cannot access the company files.
  • Your server connection is interrupted.
  • QuickBooks installation files are corrupted.
  • Multiple QuickBooks database service windows are in use.
  • Your QuickBooks company files are damage

 

To get that resolved, you can download and run our QuickBooks Desktop (QBDT) Tool Hub. This tool help fix problems and errors in QBDT. Let me guide you how:

 

  1. Close QuickBooks.
  2. Download the QuickBooks Tool Hub. Then, save it on your Desktop.
  3. Open the file you downloaded (QuickBooksToolHub.exe). Follow the on-screen steps to install and agree to the terms and conditions.
  4. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
  5. From the launchpad, click Network Issues.

 

This process will take 2-3 minutes to complete. Once done, restart your computer and try sending an email in QBDT again. 

 

For details about the tool, check out this article: Fix common problems and errors with the QuickBooks Desktop Tool Hub.

 

Additionally, here's our help content with topics and articles about QBDT. Just choose a title that'll fit your concern.

I just ran into this issue after 2 days of emailing invoices normally. If there were more than one email address, it was getting rejected.  I assumed maybe the person was no longer working for the company... until I ran into the issue again. 

 

I just recently switched from using our comcast.net email address to using Outlook, I'm still learning about Outlook so Google helped a bit, so did this post. I wasn't using semicolons but commas with spaces in between. Removing the space helped & I am at the moment able to send batch invoices with no issue. Hoping it stays this way! LOL

I don't have a solution yet but I encounter this every month when I send bills.  It sends 9 or 10 emails and then it pops up with the message - Quickbooks is unable to send emails due to network connection failure.   It probably will let you send more the next day but I send all my bills the same day so I click on save the attachment after clicking to send it - then manually mail it.   What a colossal PITA.

February 2, 2023

With one customer, I get the email cannot be sent because of network connection failure. For different customers, the QB sends the invoices via webmail just fine. Why the difference?

May 23, 2023

Mine started doing this after QB forgot my email info. I had previously had mine setup manually, but used the auto setup with google this time ( which was laborious) After setting it up it would only send 3-7 emails and then give the network connection failure message. 

After fiddling around a bit, I decided to just set it up again manually, saying "others" on pulldown menu when it asks what email provider. The outgoing SMTP server for Gmail is smtp.gmail.com then I clicked the box at bottom SSL/TLS and entered 465.  It works fine again. If you have a different provider you can look up the SMTP server info for them individually. 

If you need more info on how I did this, feel free to ask. Hope that helps someone with the same problem!

Thank you PBWCPC, you got me in the right direction.

 

I had a problem with error popping up for every computer at our office for sending out estimates or invoices (We have Gmail webmail). It started popping up randomly a few weeks before, but we just pushed the send button again, and it would send. Now though every time it happens.

 

I got it to work now, here is my fix:

For the Web Mail, select Other instead of Gmail.

Put in the stmp.gmail.com, 587, check box respectively. (Like PBWCPC says)

In Gmail, make sure you have IMAP enabled.

Make sure "Less Secure Apps" is enabled from your google account (This is what fixed it for me)

Then next time you send an email from QB, it will ask you to for your password. It worked for a couple computers in our office.

 

(Now I am having problem on another computer where it can't access the email server, but that is a separate company/email domain...not sure why though)

I have sever clients who will get more than one email e.g. [email address removed] as well as [email address removed] 

 

If any of the email addresses have changed and no longer are active e.g. jsmith no longer works at acme, you get the generic message saying qb is unable to send emails due to a network connection failure which sounds more like QB can't even ping 8.8.8.8 let alone send emails to anyone in the world.

June 2, 2023

Our client is using QB 2023 Accountant Desktop.  Webmail has been successfully configured to use Gmail with enhanced security.  Both the Intuit and Gmail security logins have been entered successfully.  She is intermittently receiving the "unable to send emails due to network connection failure" error.  Sometimes the form gets sent with a second attempt, sometimes it does not send at all, regardless of the attempts.  The intermittent nature of this error suggests it's something on the Intuit side.  Please advise.

 

June 2, 2023

We have just started having the same issue about 2 days ago.  It will send a few emails and then we get the error.  Try again later it might work. It might not. We are connected to gmail using the advanced security option.

 

Please advise a fix.

I am having the same problem all of a sudden. It started yesterday or the day before. At first when I kept trying to send emails, eventually it would go through. Now, none will go through. I tried all the same things as you. New update issue? 

September 8, 2023

We are running into this too...  We are using outlook with enhanced security.  it seems if the if the cc field has more than one email address, they are separated by a comma or semicolon and a space.  If we remove the trailing space after the comma or semicolon and keep both email addresses.  we DO NOT get a network failure.

 

[email address removed], [email address removed]  == FAILED  
[email address removed],[email address removed]  == SUCCESS.

The best part?  - if you send it without spaces.  and then SAVE the CC field when prompted...Quickbooks APPENDS a space after the comma or semicolon, basically breaking itself.

Use a comma, not a semi-colon

April 24, 2024

I ran into this issue and change out the semi-colon for a comma and removed any spaces in the CC line when adding two other recipients. It worked the first time, thought I got lucky and tried to recreate the solution, only for quickbooks to send the network error again regardless of syntax. Is there anything else I'm missing?

Let me help you get past this error message when sending emails, jorsh.

 

We can use the QuickBooks Tool Hub to fix common issues like what you're having when sending emails within QuickBooks Desktop (QBDT). Here's how:

 

  1. Close QuickBooks.
  2. Download the QuickBooks Tool Hub file.
  3. Please open the file and follow the on-screen instructions on how to install it. Make sure to agree to the terms and conditions.
  4. Double-click the icon on your Windows desktop to open the tool hub when the installation finishes.
  5. Once the QuickBooks Tool Hub is open, select Program Problems.
  6. Select Quick Fix my Program.
  7. Start QuickBooks Desktop and open your data file.

 

Thus, I'd also like to know what email provider you're currently using. This way, we can isolate the problem.

 

In the meantime, a workaround is changing the email provider set up on your QB account.
