Hello, @Bokihein.
I can share some information about resolving the error you're having when sending your invoices.
After making sure that you've updated the program to the latest release, ensure the email preference is correct since this will affect how you send transactions in QuickBooks.
Here's how:
- In QuickBooks, select Edit and then select Preferences.
- Click on Send Forms and choose Web Mail.
- Set your User Id and Edit.
- Select Use enhanced security and select OK. We’ll also ask you to sign in to your Intuit account to complete the process.
- Your Gmail sign-in page will display. Sign in and grant Intuit access.
Refer to this article for more information about checking your app preferences that may be blocking the connection to your Google account: Fix webmail password issues in QuickBooks Desktop.
There are times you'll encounter error messages about the system not being able to connect to the email server or the remote server. In case this happens in the future, I've attached a link on how to fix it: Fix Error: Could not connect to the email server. The articles I've provided above are for the United States but still work in your QuickBooks Desktop (QBDT) file.
Let me know if you need further help with your invoices. I'm always glad to help in any way I can. Have a wonderful day!
