When QuickBooks stops sending invoices after a software update, it can interrupt billing and delay customer payments. The problem may be related to changed email preferences, Outlook compatibility, Gmail authorization, or an issue with the email provider. In some cases, invoices remain pending even though QuickBooks appears to have completed the sending process.
If you experience QuickBooks invoice email not working after an update, first identify whether you use QuickBooks Desktop or QuickBooks Online and whether the problem affects every invoice or only certain messages. This guide covers practical troubleshooting steps to help restore email delivery. For additional troubleshooting guidance, contact BooksMerge at +1-866-513-4656.
A QuickBooks or email application update can change compatibility, authentication, or configuration requirements. Common causes include:
QuickBooks email preferences changed or became misconfigured.
Outlook is no longer communicating correctly with QuickBooks.
Gmail or Outlook webmail authorization needs to be renewed.
An email provider has changed its authentication requirements.
QuickBooks invoices are stuck in the email queue.
The recipient's email address is incorrect or the message has bounced.
A browser issue is affecting QuickBooks Online.
The exact cause depends on the installed version and email method. Start with the checks below before reinstalling software or changing security settings.
Begin with basic application checks before making changes to your email configuration.
Save your work and close QuickBooks Desktop.
Restart your computer.
Open QuickBooks again.
Select Help > Update QuickBooks Desktop.
Select the available update options and install any applicable updates.
Reopen QuickBooks and try sending one test invoice.
If the problem started immediately after updating Microsoft Office or Outlook, check the installed Office version as well. An outdated or incompatible Office release can interfere with QuickBooks email functions.
For related troubleshooting, you can link to QuickBooks Desktop Update Errors within this section.
Incorrect email preferences can trigger a QuickBooks invoice sending error, especially if QuickBooks no longer uses the intended email application.
For QuickBooks Desktop:
Open QuickBooks.
Select Edit > Preferences.
Choose Send Forms.
Open the My Preferences tab.
Verify whether Outlook or webmail is selected.
Confirm that the selected email method is supported and correctly configured.
Save the settings and send a test invoice.
If you use Outlook, open it separately and make sure you can send an email normally. If Outlook is missing from the options, check whether your QuickBooks version supports your installed Outlook version and whether an Outlook profile is configured.
Avoid switching email methods randomly. Confirm which application you intend to use and configure it consistently.
If QuickBooks cannot send invoices through Outlook after an update, the issue may involve the Outlook profile, application compatibility, or QuickBooks email preferences.
Try these checks:
Close QuickBooks.
Open Outlook and confirm that you can sign in and send a message.
Check that the correct Outlook profile is configured.
Confirm that Outlook is supported by your installed QuickBooks version.
Reopen QuickBooks and review Edit > Preferences > Send Forms.
Select Outlook if it is available and appropriate for your configuration.
Send a test invoice.
If QuickBooks displays an Outlook-related error, record its exact wording before attempting advanced repairs. Some issues require updating Microsoft Office or correcting the integration settings.
For official instructions, refer to Intuit's guide to fixing QuickBooks email errors with Outlook.
If QuickBooks Gmail not working with QuickBooks after an update, your Google account may need to be authorized again.
For QuickBooks Desktop using Gmail through webmail:
Update QuickBooks Desktop to an applicable current release.
Open a transaction or report and select Email.
Choose Send.
If a webmail authorization window appears, select Continue.
Sign in through the official authorization process if prompted.
Select Allow to grant the requested permission.
Try sending a test invoice.
Google and Microsoft authentication changes can require renewed authorization for supported email integrations. Do not disable two-factor authentication or share your password to bypass the issue. <Cite refs={["turn838668search5"]}/>
For QuickBooks Online, the process is different. Open the invoice, select the sending option, and check the From address. If you use a connected Gmail account, verify that it is authorized to send on your behalf. If delivery continues to fail, remove and reconnect the Gmail address using the available QuickBooks workflow.

If QuickBooks invoices not emailing is the main problem, determine whether QuickBooks failed to send the message or whether the email was sent but not delivered.
Follow these steps:
Verify the customer's email address.
Send a test message from Outlook or Gmail outside QuickBooks.
Check QuickBooks' email preferences.
Look for authorization prompts or email provider alerts.
Check the recipient's spam or junk folder.
Review any delivery failure notification.
Send one test invoice after making the necessary corrections.
If only one customer is affected, investigate the recipient's email address or email filtering. If every invoice fails, focus on your QuickBooks configuration or email provider.
After an update, you may discover QuickBooks invoices stuck in email queue. In QuickBooks Desktop, invoices marked for later delivery may remain in the queue until you send them.
Open QuickBooks Desktop.
Select File > Send Forms, if available in your version.
Review the forms waiting to be sent.
Confirm that each invoice is addressed correctly.
Check whether any invoices have already been delivered.
Select the appropriate invoices and choose Send Now if they are ready to send.
If the queue does not clear, close and reopen QuickBooks and check the email application again. Do not repeatedly resend every invoice without checking delivery status, because customers may receive duplicate messages.
For guidance on verifying delivery, see Intuit's instructions for checking whether an invoice was emailed.
A QuickBooks invoice email failed message can indicate an email configuration or delivery problem.
To troubleshoot it:
Confirm that your email provider is working.
Verify the recipient's address.
Review QuickBooks' Send Forms preferences.
Check whether your email account needs renewed authorization.
Confirm that your software versions are compatible.
Record the exact error message if the failure continues.
If the error says QuickBooks cannot connect to the email server, review the provider-specific server and security settings. Use the settings supplied by your email provider rather than guessing server names or ports.
If the issue affects other QuickBooks features too, QuickBooks Tool Hub Download may be a useful internal link for readers who need to troubleshoot broader Desktop program problems. Tool Hub is not a dedicated fix for every email issue, however.
If you use QuickBooks Online and invoice emailing stopped after a browser update, test whether the issue is browser-specific.
Sign out of QuickBooks Online.
Close and reopen your browser.
Sign in again.
Open the affected invoice and verify the recipient details.
Try a supported, updated browser or a private browsing window.
Check Intuit's service status if multiple invoices or users are affected.
If the problem happens only in one browser, review its extensions and cached data. If it occurs across multiple browsers and users, investigate account settings or a service disruption instead.
If you need to deliver an invoice before resolving the email problem, check whether your QuickBooks version allows you to download or print the invoice as a PDF. You can then send the PDF through your regular email application, following your business's privacy and recordkeeping procedures.
Before sending it manually:
Confirm the invoice details and total.
Verify the customer's email address.
Check whether QuickBooks already sent the original invoice.
Record the manual delivery.
This workaround can help avoid billing delays, but it does not correct the underlying QuickBooks email problem.
Keep QuickBooks and your email application on compatible versions.
Check email preferences after major software changes.
Reauthorize supported Gmail or Outlook integrations when prompted.
Maintain accurate customer email addresses.
Review pending invoices before resending them.
Keep regular backups of your QuickBooks company file.
Record the exact error message when a failure occurs.
Check official release notes when an issue starts immediately after an update.
The update may have affected email preferences, Outlook compatibility, or account authorization. Start by checking the email application independently, reviewing QuickBooks' Send Forms settings, and verifying that your software versions are compatible.
Check the internet connection, confirm the customer's email address, verify the email configuration, and test one invoice. If the problem began after an update, check for additional compatible updates or authentication prompts.
Outlook may have an incompatible version, an incorrectly configured profile, or a problem communicating with QuickBooks. Confirm that Outlook sends emails independently, then review the Send Forms preferences and compatibility requirements.
In QuickBooks Desktop, open File > Send Forms if available and review the pending messages. Confirm which invoices have already been delivered before selecting Send Now to avoid duplicate emails.
Check that Gmail works in your browser, then verify the authorization and email settings in QuickBooks. Follow the official reconnect or authorization process when prompted, and avoid disabling security protections.
Yes. If your version allows it, save or print the invoice as a PDF and send it through your regular email application. Verify the delivery status and record the manual email to prevent duplicate billing.
QuickBooks invoice email problems after an update may be caused by changed email preferences, Outlook compatibility, Gmail authorization, or pending messages. Check the email application first, review QuickBooks settings, and confirm delivery status before resending invoices. If the problem continues, use the exact error message to guide further troubleshooting rather than changing unrelated company-file settings.
