Let's get you back up and running, VirginiaVet.

I appreciate your effort in performing some troubleshooting steps beforehand. To get this sorted out, updating your QuickBooks Desktop to its latest release is a good start when it comes to fixing program-related issues. This makes sure you have the most recent fixes and security updates.

Here's how:

1. Click Help at the top menu bar and choose Update QuickBooks Desktop.
   
2. Go to the Update Now tab.
3. Select the Reset Update and click Get Updates to start the download.
4. Once done. Hit OK and restart QuickBooks.
   
5. When prompted, accept the option to install the new release.

Once updated, go to the Web Mail Preferences in QuickBooks Desktop and check your email settings from there. See the steps below:

1. From the QuickBooks Edit menu, select Preferences.
2. On the left pane, select Send Forms.
3. Under My Preferences, select the email account you are using, then select Edit.
4. In the Edit Email Info screen go to the SMTP Server Details section and set the server name and port to your email provider settings.

If you're still getting the same result, you can go through the following article and proceed to Solution 3: Fix Error: Could not connect to the email server.

I'll be adding this write-up: Connect your email to QuickBooks Desktop. You'll find more details about connecting emails with QuickBooks as well as a list of SMTP Servers and Ports.

Let me know how it goes by leaving a reply below. I want to make sure you're able to work your Gmails with QuickBooks. I'll be right here if you need anything else. Have a good one!
