I'll make sure you'll get the invitation email, @SWH4911.
Have you checked your email's spam folder? If not, I recommend that you check it and look for the invitation email from there. Once you've found it, accept the invitation to access QuickBooks Online (QBO) using your corporate email.
If you have and the invitation email isn't visible, I recommend resending it. Make sure you have a stable internet connection and that you've entered the email address correctly to avoid any delays.
