Why isn%27t my QB 2012 able to send emails all of a sudden%3F I was forced to get Win 10

Thanks for posting here in the Community, @birdbox.

Windows 10 isn't compatible with QB 2012. This is the reason you're unable to send emails through the program. 

To help fix this, you'll need to upgrade QB 2012 to the latest version. You'll first have to create a backup of your company file before the upgrade process. This protects your data from accidental loss. 

To upgrade, you'll need to install and activate your new QuickBooks. Then, prepare the file for update. For detailed steps, go through this article: Upgrade To A New QuickBooks Desktop Version. 

Once upgraded, you'll have to set up Outlook as your default email service in the program. the Before you get stared, check the system requirements for QuickBooks Desktop. This is to make sure your Outlook is compatible with the software version. Here's how: 

1. Create an Outlook email profile. 
2. Contact your ISP (Internet Service Provider) for your email information. 
3. Set up Outlook. 
4. If you're unable to see Outlook as an option, you can fix it by checking out this article: Outlook is Missing in Send Forms Preferences.  

You can visit this article for detailed steps: Set Up Email Service. After that, you can now email your sales forms through the software.
