Update Windows OS

QuickBooks and every other application depend on the OS to run and execute their functions efficiently.

1. Launch the MS Office on your system and click File on the left.
2. Tap Accounts (Office Account if you run MS Office directly) and navigate to the Product Information tab.

Method 2- Set MS Outlook/Webmail as Default App in the System Settings and QB Preferences

QuickBooks cannot send or receive emails on its own and uses your system’s default mailing app to deliver them. In case the mailing app set as default on your system or QB preferences is incompatible with the software, sending emails will no longer be a luxury for you. You’ll have to change the system settings and QB preferences to send emails without problems. Refer to these steps-

1. Launch the Control Panel window and access the Apps option from the left menu.
2. Click Default Apps and select Mail in the following window.
3. You must select from MS Outlook or Webmail to set it as the default mailing app on your computer.

Change QuickBooks Preferences

After configuring the system settings, you must also set MS Outlook as the default mailing application in QuickBooks Preferences. The software might ask for your Username, Password, Incoming email server address, incoming email server type, and Outgoing email server address. Contact your email/Internet provider for the details (if required) and use the following steps to connect the email to your QB Desktop-

1. Launch your QuickBooks Desktop and access its Edit menu from the top.
2. Tap Preferences and click the Send Forms option.
3. Select Outlook from the list and tap Add to set it as default.

If you encounter problems with emails after configuring the system settings and QB preferences, check out the next solution.

Method 3- Repair the Corrupt Mapi32.dll File

The Mapi32.dll file is a critical component of the Messaging Application Programming Interface (MAPI) used to connect QuickBooks and all the PC applications with the email clients (Webmail, MS Outlook). A QBmapi64 out of memory error on Windows 11 develops instantly when the Mapi32.dll file gets damaged and fails to run when you try sending emails. You must repair the Mapi32.dll file as shown in the following steps-

1. Open the File Explorer (Windows + E) and tap the View option at the top.
2. Ensure the Hidden items checkbox is marked and go to the search bar in the File Explorer.
3. Type ‘fixmapi’ and go to its location using the search results.
4. Find Fixmapi.exe from the list and double-click it to run the application.
5. Perform all the steps instructed by the application and wait until the Mapi32.dll file is completely repaired.
6. Open your QuickBooks and try setting up or sending emails.

If the error is still not fixed, you must proceed to the next method.

Method 4- Check the Internet Speed and Configure the SSL Settings

A lousy internet speed threatens tasks in QuickBooks Desktop requiring an internet connection, like downloading updates, sending emails, etc. You must ensure that the Internet speed delivered by your service provider complies with the QB requirements of 3Mbps on average and a minimum of 1.5Mbps. Here’s a quick way to run the Internet Speed Test-

1. Access Google’s homepage on your web browser and search for ‘Internet speed test.’
2. Click the first link to open the online tool and tap Start to run the Internet Test.
3. Wait for it to complete and compare the results with the QB requirements.

If the Internet speed is satisfactory, you can proceed to configure your SSL settings. However, if it is too low for QB to run smoothly, you must try turning the router On and Off, check for cable damage, or change your network service provider.

Adjust the SSL Settings on your Windows

Secure Sockets Layer or SSL is a security protocol Windows OS uses to establish an encrypted link between the servers and your web browser. This ensures data exchange without the risks of unauthorized access or malware. Unfortunately, QuickBooks won’t be able to send emails if the SSL settings on your Windows aren’t correctly configured and stop the software from accessing the internet. Configure the SSL settings using the following steps-

1. Launch the Internet Properties window through the Control Panel or directly using the ‘inetcpl.cpl’ command in the Run window.
2. Navigate to the Advanced tab and look for SSL settings checkboxes in the list (located at the bottom).
3. Only mark the Use SSL 3.0 checkbox among the SSL settings checkboxes and move to the Content tab.
4. Tap Clear SSL state and close the settings window after saving the changes.
5. Launch your QB Desktop and try setting up emails again.

If you cannot send or set up emails in your QuickBooks, jump to the next solution.

Method 5- Change the QuickBooks Folder Permissions

QuickBooks out of memory error while emailing can also emerge if the software fails to access the location of its program files. You’ll also see an error message on the screen or experience a lag in the software when you select a file to send through email and QuickBooks fails to access it due to a lack of folder permissions. If you are facing problems while sending some specific files through email, use the following steps to configure the QB folder permissions and use the same steps on the folder containing the files you want to send through email-

1. Right-click on the QuickBooks folder in C: Users\Public\PublicDocuments\AppData\Intuit\QuickBooks20XX and go for the Properties option in the list.
2. Move to the Security tab and click your Account in the list.
3. Tap Change Settings (if the option is available) and single-click the Full Control checkbox in the window.
4. Save the changes by clicking Apply and try sending emails from your QB Desktop again.

Run QuickBooks Desktop as Administrator

Rather than changing the folder permissions individually, you can also grant admin rights to your QB Desktop. Running the program as an administrator allows it to access all the system files without interruption and prevents it from Windows Firewall restrictions. You can either assign admin privileges to QuickBooks or sign in with your Windows admin account. Here’s how-

1. Go to the QuickBooks folder and right-click QuickBooks.exe (Software launch icon) inside it.
2.  Click the Compatibility tab and single-click the Run this program as Administrator checkbox to run it as administrator.

Or

Sign in as a Windows Admin User
