Common Errors When QuickBooks Email Stops Working

When email stops functioning in QuickBooks, you may encounter one or more of these issues:

• QuickBooks freezes when sending an email
• Error: "QuickBooks is unable to send your emails to Outlook"
• MAPI32.dll errors
• Nothing happens after clicking "Send"
• QuickBooks crashes when trying to send forms

Why is QuickBooks Email Not Working?

Here are some of the most common causes:

1. Incorrect Email Settings

QuickBooks depends on precise configuration settings to communicate with email applications like Outlook, Webmail, or Thunderbird.

2. Damaged or Missing MAPI32.dll File

This Windows component is essential for email integration. If corrupted, QuickBooks can’t send messages.

3. Unsupported Outlook Version

Certain versions of Outlook are not compatible with some QuickBooks Desktop versions.

4. Administrator Permissions

QuickBooks may lack the necessary admin privileges to send emails via your default mail client.

5. Faulty QuickBooks or Windows Installation

Outdated or corrupted installations of either QuickBooks or Windows can prevent email functionality.

How to Fix QuickBooks Email Not Working

Let’s dive into tried-and-tested solutions to restore email capability in QuickBooks.

Solution 1: Check Your Email Preferences

1. Open QuickBooks and go to:
2. Edit > Preferences > Send Forms
3. Click the My Preferences tab.
4. Make sure the correct email client is selected.
5. Click OK and restart QuickBooks.

Solution 2: Run QuickBooks as Administrator

• Right-click the QuickBooks icon
• Select Run as administrator
• Try sending the email again

This ensures QuickBooks has full access to your system’s resources and email settings.

Solution 3: Repair MAPI32.dll File

1. Close all programs.
2. Go to C:\Windows\System32 and locate MAPI32.dll
3. Rename it to MAPI32.old
4. Restart your system
5. Run Fixmapi.exe (also found in the System32 folder)

This process repairs damaged messaging interfaces that prevent QuickBooks from sending emails.

Solution 4: Set Outlook as Default Mail App

2. Select Outlook
3. Click Set this program as default

This ensures QuickBooks connects to the correct mail client.

Solution 5: Update QuickBooks and Windows
