Why isn't the email feature working for me? Trying to email invoice from Quickbooks online from my iMac. Reset my email address and tried different emails addresses.

Hey there mdsdcontracting,

Welcome to the QuickBooks Community! Thanks for reaching out to us here. Being able to email invoices from QuickBooks is important. I can provide some information.

It may be browsing data on your system that is preventing the software from doing what it is supposed to do. Here are some steps to resolve issues that are caused by browsing data:
 

• Clear your browser cache if you're using a browser
• Try a browser if you're using the app
• Try a private browser window
• Try another browser type
• Make sure you're using a supported browser and system
• Reset your Internet or try on another computer or device
• Uninstall the QuickBooks Online App, and re install it.

If you're still unable to email invoices after trying these troubleshooting steps, I recommend reaching out to the support team outside of the Community. They'll be able to verify your account details in a secure setting, as well as view your screen to better assist you. They also have the necessary tools to create a ticket to get the issue resolved if they see fit. You can reach them by following one of these methods:
