Understand the Root Cause and Identify

Let’s take a look at the reasons that contribute to this frustrating QuickBooks email problem. Discovery of causal reasons is the foremost step towards constructive troubleshooting and solution.

Common Reasons Behind the Email Connection Failure

It is very important to know about the main culprits of this issue in order to diagnose the errors effectively. Following are some of the most common causes for email connection failure while using QuickBooks:

• Incorrect Email Settings in QuickBooks

QuickBooks needs to be configured with certain values to be able to connect to your email server, these include the SMTP server address, port number as well as the authentication details. Badly configured settings are the leading cause of connection failures.  

• Interference of Firewall or Antivirus

The QuickBooks software can be prevented from accessing necessary email ports or executables by a firewall embedded in your machine, or by a third-party antivirus application.  

• Internet Connectivity Issues

If it is slow and unreliable, the internet may not, at times, allow QuickBooks to connect to the email server.

• Outdated QuickBooks Version

At times, using an outdated version of QuickBooks can be a source of compatibility problems with email servers.  

• Corrupted Network Data Files (.ND)

Through a network, QuickBooks may access corporate files because of these configuration files. Sometimes, corruption in these files can mess up the functionality of email.

• QuickBooks Database Server Manager Issues

In case of using QuickBooks in a multi-user environment, inconvenience with Database Server Manager may affect different functions including email.  

• Internet Explorer Settings

QuickBooks tends to use the Internet Explorer settings for some functions related to the internet despite it not being the case in some instances your primary browser. Poor IE settings may destroy email connectivity.

• Email Provider Issues

Though rarer, temporary downtime or other forms of modification of the server settings on the email provider side could still lead to connection problems.

• SSL Certificate Issues

Secure Socket Layer (SSL) certificates ensure secure communication. Problems with the certificates, either on your side or that of the email server, can cause a connection error.

Identifying the Email Server Connection Error

The “Could not connect to the email server” error shows a definite break between the QuickBooks application and the server assigned to send your emails. The reasons may be many, both from your local system and from the email service provider.

QuickBooks Unable To Connect To Email Server: Troubleshooting Guide

With these problem areas that can trigger this error being identified, let’s look at some of the effective ways to fix this as soon as possible and get your QuickBooks emailing back on track.

Solution 1: Update QuickBooks to the latest version

• After selecting the appropriate product, download the update file by clicking the Update button.
• To learn how to set up QuickBooks to download and install the latest updates automatically, you have to select the option that highlights Setup Automatic Updates.

Solution 2: Examine the webmail preferences settings.

If you are using an internet based email, such as Gmail, Outlook.com or Yahoo Mail, QuickBooks needs certain settings to be configured in order to connect. Also, you should check that all of the settings in webmail preferences are valid.

• In QuickBooks, head to “Edit”> “Preferences”
• You must choose the Email option after clicking on Send Forms in the left side.
• Select “Web Mail” as the mail provider.
• Click the “Add” button.
• Enter your email address.
• Now, you have to select your email provider from the drop-down list. E.g. Gmail, Outlook, Yahoo. The server details will most likely be pre-populated on QuickBooks.  

For Gmail:

Make sure that the “Less secure app access” is turned on under your Google settings account (thought Google is phasing this out, you may use App Passwords instead). Otherwise, go to your Google account and set up an App Password to use on QuickBooks.

For Outlook.com/Microsoft 365:

Most probably, you may be required to enable SMTP in your account settings. Take into consideration using App Passwords if two-factor authentication is activated.

For Yahoo Mail:

You may need to create an App Password on your Yahoo account and key in that in QuickBooks.

• Press “OK” on all windows in order to save settings.
• Just send an email test from the QuickBooks.

Solution 3: Verify and Reset Internet Explorer to Default

The steps listed below highlight certain parts of troubleshooting faults and problems with QuickBooks Desktop installation according to the email server. The instructions below describe how to resolve QuickBooks installation problems on Mac and Windows, and resolve problems related to the email error that users encounter:

• Launch Internet Explorer on your PC, then click the gear icon or the Tools menu (Alt+T).
• Select Internet Options by clicking.
• Click the Advanced tab and then select Restore Advanced Settings after completing the previous step.

• After choosing to restore, click OK, and then exit the browser.

Solution 4: Check if QuickBooks Access is blocked by any antivirus or third-party software

Your antivirus program or other security programs may be wrongly marking QuickBooks as a threat and denying its access to the email ports.

• Temporarily disable your antivirus software.
• Why not send an email from a QuickBooks? If it does, then your antivirus is probably to blame.
• Reboot your antivirus and then set it to allow QuickBooks executables (usually found in C:\Program Files (x86)\Intuit\QuickBooks XX) and the required email ports to the firewall of your antivirus. Check the instructions on your antivirus application documentation on how to add exceptions or allow programs.
• Likewise, verify the setting of any other firewall software that you are working with (including the Windows Firewall) to ascertain that QuickBooks is not blocked. For QuickBooks.exe and the associated email ports, you might need to make exceptions.

Solution 5: Control the QuickBooks Database Server Manager

If you need the access of business file in the multi-user scenarios, the QuickBooks Database Server Manager is needed.  Ensure it’s running correctly.

• On the server computer, to which the QuickBooks company file is located, open the “Run” dialog box (Windows key + R),
• Type services.msc and press Enter.
• In the services box, you must locate QuickBooksDBXX. You need to confirm whether the Status of the service says Running. Otherwise, you have to right-click the service and then choose Start button.
• Now, you will have to make sure that you are setting the Startup type to Automatic. You have to click on “Startup type” after right-clicking the service, choosing Properties, and, if necessary, providing the desired outcomes.
• If the service is running, re-start its service. Right-click and select “Restart.”
• Launch QuickBooks on a work-station and attempt to send an email.

Solution 6: Rename the Network Data Files (.ND)

In case you are using QuickBooks in a multi-user environment or if you are accessing your company file across a network, the corruption of .ND files can sometimes lead to an array of problems, including email connectivity problems. Renaming of these files causes QuickBooks to reconstruct them.

• Close QuickBooks on all workstations.
• If the access is needed for the QuickBooks Company file, you need to find its location. The extensions of the files contained in this folder will be .qbw, .qbb, and .ND.
• Search for files having extension as “.ND” (such as YourCompanyName.qbw.nd and YourCompanyName_LOCAL_DB.nd).
• Open a dialog box by right clicking on each .ND file and then rename it.
• There is a requirement for renaming the files to .old (e.g., YourCompanyName.qbw.nd.old and YourCompanyName_LOCAL_DB.nd.old).
• You will have to launch QuickBooks if you wish to gain access to the company file. As a result, QuickBooks will create new.ND files.
• See how an email is sent from QuickBooks.

Solutions Based on Different Email Providers (Gmail, Outlook, and Yahoo)

As previously mentioned, the exact steps to follow in making configurations may differ a little bit depending on the email provider that you are using.

Gmail

• Switch on “Less secure app access” in your Google account (if the option is available) or, better, create and complete the security measures of App Password.
