It's great to see you here, @CHRISD11.
I want to make sure you're able to send your email in QuickBooks. But before anything, I'd like to ask what email provider are you using or is connected in the program. This will help me check if there is an ongoing issue with your email.
For now, if your password isn’t accepted, see QuickBooks will not accept my webmail password for more information on how to fix it.
Please let me know if the steps work and mention me if you add additional details for this email issue. I'll be more than happy to help.
