Office365 MFA Broke Email feature in Quickbooks 2020

I'm here to share troubleshooting steps to fix the error, jingxi02.

This error message usually occurs when we made changes with the settings of our email provider. 

We can fix this by making sure that QuickBooks isn't set to automatically run as admin.

Here's how:

1. Close your QuickBooks Desktop company file.
2. Click the Windows Start menu.
3. Enter QuickBooks into the search bar and then right-click the QB icon, select Open file location.
4. Right-click on the QuickBooks.exe file and select Properties.
5. Go to the Compatibility section.
6. Select the Run this program as Administrator option.
7. Go to Apply and then OK.

If the error persists, let's try setting up Outlook as your preferred email provider. Here's an article for more information: Set Up Outlook To Work With QuickBooks.

I'm just a post-away if there's anything that I can help. Take care!

That is the first thing we tried.  The app is not running as administrator.  The Outlook is set to default email program.  There is no change in the computer as all.  The only change is the Email now requires two factor authentication.  I think the problem is Quickbooks just doesn't know how to handle the Outlook with 2FA.

We are in the same situation as this guy.  Apparently, Intuit hasn't had any resolution or not even aware of this issue for two years.

Hello there, @jingxi02.

We have to try some recommended troubleshooting steps with your Microsoft application. Just as a reminder, these steps might be too technical and, you can ask the assistance of an IT professional if you're uncomfortable doing them.

Here's how:

1. Let's ensure that you update to the latest release of QuickBooks Desktop.
2. Let's verify if your Outlook is compatible with the version of your QuickBooks Desktop. First, let's determine the version of your Outlook: Outlook version information and Outlook's Ribbons. Next, let's verify if your Outlooks version is compatible with QuickBooks Pro 2019. Click the link and go to the Software Compatibility section for QuickBooks Pro/Premier 2019 and Enterprise 19.0.
3. Make sure that the QuickBooks default email program is Outlook.
4. Set Outlook as the default email program in Internet Explorer.
5. Edit the Mail Profile settings in Windows. Change the WIN.INI file in Windows.
6. Run the Detect and Repair tool in Outlook.
7. Uninstall and reinstall Office and your QuickBooks.

 For in-depth information and detailed instructions, you can refer to the Outlook is missing in QuickBooks Desktop Send Forms preferences article.

Please give these steps a try. Keep me posted how on the results by leaving a comment in this thread. Take care always.

The Quickbooks software has been updated to the latest patch on 2020 version.  I don't think this is anything with the Outlook or the computer setting or the Quickbooks installation at all.  As I said, everything was working perfectly before the email enabled the  two factor authentication.  As soon as the 2FA is enabled on the mailbox, the Quickbooks stops working with the Outlook.  I already tried disabling the 2FA in the user emailbox, and Quickbooks works again with the Outlook. as soon as the 2FA is disable in the email box.  So the issue is strictly Quickbooks just doesn't know how to generate email when the emailbox requires 2FA.  Intuit should look into this as bug or lag of feature support.

I have the same problem and had to switch to let QB send the emails.  You have to enter the MFA password the first time you send and email thru QB.  I have not figured out any other work-a-round. Hope this helps. 

I have seen the issue be resolved by setting up an "app password" in 365. it is similar to using "less secure apps" with G Suite. Here is a link.
