In the event that a company gets invited by the wrong email address, do not worry there is a fix for this.
If you are an admin inviting another user, you have control of their company page while they are still in the inactive state.
Navigate to the company page and scroll down to the Account Managers panel.
Select their company name.
Click Add Point of Contact.
Now you can enter the correct email address and send an invite.
Once the user has activated the account they will take over the admin control and can delete the user with the incorrect email address.
