Can an email address be invited to multiple teams in Cursor?

Our company uses the same email suffix across multiple teams in Cursor. My current team has configured SSO (Single Sign-On) with login restrictions enforced at the IDP (Identity Provider), allowing only team members to log in. However, members from another team cannot access their account. Here are my questions:

  1. Can the same email address exist in multiple teams simultaneously?
  2. If we configure the email addresses from the other team to log in successfully, will those users be automatically added to my team, and will this incur additional charges to our billing?
