QuickBooks is a widely used accounting software designed for small and mid-sized businesses. One of its vital features is the ability to send invoices, reports, and other documents directly through email. However, many users occasionally encounter a frustrating issue where QuickBooks is not sending emails.
This article outlines the top 10 solutions to troubleshoot and resolve the issue efficiently, ensuring seamless communication with clients and vendors.

1. Check Your Email Preferences in QuickBooks
The most common reason QuickBooks fails to send emails is incorrect email preferences.
How to Fix:
Go to Edit > Preferences > Send Forms.
Check if the correct email provider (e.g., Outlook, Webmail) is selected.
Re-enter the email ID and re-authenticate if needed.
Make sure QuickBooks is configured to use the correct email client and that your credentials are up to date.
2. Ensure QuickBooks is Running as an Administrator
Sometimes, QuickBooks needs administrative privileges to access email functions, especially if it's integrating with Outlook.

How to Fix:
Close QuickBooks.
Right-click the QuickBooks icon on your desktop.
Select “Run as administrator.”
If this resolves the issue, adjust your shortcut settings to always run QuickBooks with administrative privileges.
3. Update QuickBooks to the Latest Release
Outdated software often contains bugs that may prevent emails from being sent.

How to Fix:
Open QuickBooks.
Go to Help > Update QuickBooks Desktop.
Install any available updates and restart your system.
Keeping QuickBooks updated ensures compatibility with your email client and fixes known glitches.
4. Verify Internet Explorer Settings
QuickBooks Desktop uses Internet Explorer (or its legacy settings) for some background functions, including email.
How to Fix:
Open Internet Explorer.
Go to Settings > Internet Options > Programs tab.
Ensure your default email program is set correctly.
Under the Advanced tab, reset settings to default.
Outdated or incorrect browser settings can interfere with email delivery.

5. Check MAPI32.dll File Integrity
QuickBooks uses the MAPI32.dll file to communicate with email programs like Outlook. If this file is damaged, QuickBooks can’t send emails.
How to Fix:
Close all programs.
Search for and run the fixmapi.exe utility on your system.
Restart the computer.
This resets the MAPI32.dll file and often resolves communication issues.
6. Check for Email Client Compatibility
QuickBooks Desktop works best with full desktop versions of email clients like Microsoft Outlook. Using web-based or unsupported clients can cause issues.
Recommended:
Use Microsoft Outlook (2010-2021) or Outlook 365 desktop version.
Avoid web-only versions like Gmail or Yahoo unless configured through QuickBooks Webmail.
If you use Gmail, make sure your account allows access from less secure apps, or enable two-factor authentication and generate an app password.
7. Repair Microsoft Office
If the email client (usually Outlook) is corrupted, QuickBooks won’t be able to communicate with it.
How to Fix:
Close all Office programs.
Go to Control Panel > Programs and Features.
Select Microsoft Office, then click Change > Repair.
This repairs the Outlook installation and can resolve issues with email functionality.

8. Reconfigure QuickBooks Email Settings
Sometimes email settings in QuickBooks get misconfigured due to software updates or external interference.
How to Fix:
Go to Edit > Preferences > Send Forms.
Click on My Preferences and then Add.
Enter the correct SMTP server settings, port number, and SSL requirement based on your email provider.
Common SMTP settings:
Gmail: smtp.gmail.com, Port 587, SSL required.
Outlook: smtp.office365.com, Port 587, TLS required.
9. Temporarily Disable Antivirus and Firewall
Security software might block email functions in QuickBooks.
How to Fix:
Temporarily disable your antivirus and firewall.
Try sending an email from QuickBooks.
If it works, add QuickBooks and your email client to the list of allowed applications.
Do not forget to re-enable your security software after testing.
10. Reinstall QuickBooks Desktop
If none of the above methods work, QuickBooks itself may be corrupted and may need reinstallation.
How to Fix:
Use the QuickBooks Clean Install Tool to uninstall and reinstall the software properly.
Restore your company file and reconfigure email settings.
A clean install often resolves deeply embedded configuration issues or corrupted files.
Final Thoughts
Emailing directly from QuickBooks saves time and helps streamline operations. When this feature malfunctions, it can disrupt business communication and cash flow. However, by following these top 10 solutions, you can quickly identify the issue and get your email functionality working again.
If the problem persists despite these steps, it might be time to consult with a certified QuickBooks ProAdvisor or contact Intuit Support for more advanced help.
