QuickBooks Desktop Not Saving SMTP App Password for M365

Once you've authorized QuickBooks with your webmail account, QuickBooks Desktop (QBDT) will securely store your webmail credentials, @edzila. Let me walk you through some troubleshooting steps to fix this.

First, ensure that your QBDT is updated to the latest release.

If you are using Windows 10 or 11, you can check the Credential Manager in Windows. In particular, this step will allow you to view and delete saved credentials for signing into connected applications. Therefore, I recommend collaborating with a computer expert or an IT professional on this matter.

In the Credential Manager, look for any incorrect or outdated entries related to the M365 email account, and review or modify them. Then, reconnect to the webmail within QBDT: Connect your email to QuickBooks Desktop.

Once done, you can try sending an invoice again to test it if it resolves the problem.

If the issue persists, consider temporarily turning off your User Account Control as this can be an issue regarding user access permission. In this step, please know to turn it back on after this to prevent security risks on your computer. Here's how: 

1. On your keyboard, press Windows+R to open the Run window.
2. Type Control Panel. Then select OK.
3. Select User Accounts. Then select User Accounts (Classic View).
4. Select Change user account control settings. (Note: If you are prompted by UAC, select Yes to continue).
5. Move the slider.
   • Set to Never Notify and select OK to turn UAC OFF
   • Set to Always Notify and select OK to turn UAC ON ( Note: if prompted by UAC, select Yes to continue.)
6. Restart the computer.

Thank you, Jeff. I appreciate your insight. I am myself an IT professional, so no worries there. I will dig into these suggestions. I was worried that QuickBooks desktop was still only supporting basic authentication. 

Unfortunately, none of these solutions resolved the issue. The SMTP password still isn’t being saved persistently.

Just to clarify, QuickBooks Desktop is configured to use WEBMAIL, not OUTLOOK. This problem only started after the user enabled MFA on their Microsoft 365 account and generated an App Password for QuickBooks to send outbound emails.
