Solution 13: Verify Email Settings and Antivirus Restrictions

If you are experiencing a similar problem, we recommend checking your email settings, as some configurations and filter options may be preventing emails from QuickBooks Desktop.

• Make sure you enable access for less secure apps and set access preferences for specific applications such as QuickBooks.
• Furthermore, be aware that antivirus software may restrict connections.
• Review your antivirus settings, disable them if required, and then try emailing yourself again to see if there is any improvement.

Solution 14: Access a Sample Company File

Let’s try opening a different company file to see if the problem is isolated to one file rather than the full application. Follow the below steps:

• Go to QuickBooks’s File menu, which is found in the upper left corner.
• Select “Close Company.”
• In the No Company Open window, click the drop-down arrow next to the option to open a sample file.
• Click on a different company file that has an invoice template in it.

Now try emailing the invoices again. The data in your current company file might be harmed if you open the sample file. In that situation, use the Rebuild Tool as follows:

• Click File, then Utilities.
• Select Rebuild Data.
• After it has resolved the difficulties, return to File and Utilities.
• Tap Verify Data.

In another situation, repair QB Desktop using the Install Diagnostic Tool and Quick Fix My Program (Solution 2) to resolve the software’s damaged components.

Solution 15: Add RAM to your PC

Sometimes you may have a short memory in your RAM, resulting in the qbmapi64 out-of-memory error. Increasing the space may help to solve the problem.

Solution 16: Update and Make Microsoft Outlook the Default Email Client

To update MS Outlook follow the steps:

• In Microsoft Outlook, select the File tab.

• Click Update Now.

Now, set up Microsoft Outlook as your default email app:

Now, add an email address as follows:

• Access the File menu in the Microsoft Outlook.
