I can no longer email invoices

I've checked our files to see if there's an open investigation, Ocmkt. I found none. Let me help you email the invoices.

I'll share a few possible why you're unable to send the transaction:

• The email is set up incorrectly.
• A damaged QuickBooks installation.
• Domain admin is blocked.
• Account security settings from your email provider.

First, let's make sure QuickBooks is updated to the latest release. Our program periodically provides release and updates to fix emailing concerns and add new features.

Then, let's check the email preferences. Here's how:

1. Click Edit.
2. Select Preferences.
3. Click Send Forms, then go to the My Preferences tab.
4. Select the email you're using, then click Edit.
5. In the Server Name field, ensure the server name matches your email provider's settings.
6. Click OK, then OK again. 

Once done, you can try to send the invoices to your customers. 

Although, if you've encountered an incorrect password message, I'll provide you the article with the steps to fix it. 

You can keep in touch if you need more help from this.
