I'm using Qb desktop pro 2017. I have always sent invoices through my Thunderbird email program without issues. Since I was forced to update to windows 10, my invoices send through quick books, but, when sending, it shows the inv. attachment, says invoice was sent successfully and when the customer receives the email there is no attachment. It seems that sometimes it works other times it doesn't.  HELP!!???

Let's make sure that your customer's PDF reader is updated, Scot1012.


One of the possible reasons why they're unable to see the attachment is when their Abode Reader is outdated.


You can share this article with them for the detailed steps to update it: How to update, repair, or re-install Adobe Reader/Acrobat. Then, go to the How to update Adobe Reader/Acrobat section.


Once updated, let's try sending an invoice with the attachment again.


If you want your customers to pay their invoices online, you can check this article: Let your customers pay invoices online.

Thank you for the response. I am having them try this, but, the problem isn't that the attachment won't open. The problem is that the attachment isn't there to try to open. Is there a setting that will send the emails through my thunderbird email program like it used to? I never had an issue then.



Let's get the missing attachments to appear on your customer's email, @Scot1012


It could be the Mozilla Thunderbird version your customer is using isn't updated. That's why no attachments are showing when they receive the email. 


To help fix this, have your customer update their Thunderbird program by performing the steps below. 

  1. Go to Menu at the upper right. 
  2. Select Help.
  3. Choose About Thunderbird
  4. When the updates are ready to be installed, click Restart Thunderbird to Update


Also, you'll have to make sure your Thunderbird program is updated. This fixes the program-related issues. Once done, you can send the invoices with attachments to your customer again. 


If the same issue persists, you might consider using Webmail as an alternate email option. Then, use the SMTP setting that you have in your Thunderbird email client. For detailed instructions, visit this article: Set Up Email Service


I'm just a comment away if you need further assistance. Have a great rest of your day, @Scot1012
