I know some reason why your new admin is not getting the invitation, k-brown. I'm pleased to discuss this matter thoroughly, including the ways to help address this concern.

In QuickBooks Online, there are several reasons why invited users aren't receiving their email invitations. Here are the following:

• The mail servers can block the email, which places the invitation within their junk or spam folder.
• Your company's email address was entered incorrectly in the software.
• Email invitation already expires, as it will expire after 48 hours once sent.

Aside from verifying your new admin's email address, let's ensure your email address is entered accurately from your company settings. Here's how:

1. Head to the Gear icon, then Account and settings.
2. Choose the Company tab and click the Edit icon from the Contact info section.
3. Please re-enter the company email address carefully and avoid using extra characters or leaving blank spaces.
4. Select Save and Done.

After that, you can proceed to Steps 2-3 in this article to ensure the new user has an Intuit Account so you can resend the invitation: What to do if invited users did not receive your email invitation in QuickBooks Online.

On the other hand, you can always keep track of the changes made within your company file, including who made these changes. For more information, consider skimming this material: Use the audit log in QuickBooks Online.
