Intune Connection Setup/Change Email

Trying to get our Intune tenant connected so that we can start to purchase organizationally owned Android phones and manage them within Intune, similar to what we have done with Apple. 

When I set up the enrollment to connect to Managed Google Play, I foolishly used my Microsoft account to connect them. I thought better of it and thought I’d try to add a different email to our tenant, and connect using this instead. I’ve tried to add this new email by inviting it through Google Admin. I get prompted to log in using my Microsoft account, when I do this, I get the following:
 

The user I’ve invited, still shows up as “pending” in Google Admin. What else do I need to do so I can use this new account instead of mine?
