I appreciate you for chiming in on this thread, safetyfirst.

Intuit takes account and data security very seriously. Please know that this isn't the experience we want you to encounter. Let me guide you in spotting scams and ensure you'll be able to file a report in QuickBooks Online (QBO).

The sender ID "do_ not_reply@intuit.com" isn't listed in the Sender Policy Framework (SPF), an email authentication system that prevents email spoofing. If Sender ID filtering is enabled, emails from do_not_reply@intuit.com are automatically rejected.

That said, you'll have to contact your IT person or domain provider to temporarily disable Sender ID filtering or get help on what’s causing you not to receive the email. 

Furthermore, it's best to get in touch with our customer support. This way, you can file a report about your experience, and we can take action, so this won't happen the next time.

I'll also share this article so you can recognize official Intuit correspondence and websites: Identify suspicious activity, phishing scams, and potential fraud.

Please don't hesitate to reply if you have concerns about spotting email spoofing in QBO. The Community is here to help anytime.
