Hi there,
Welcome to Box Community and glad to assist!
Yes, it's true that everyone in your mailing list would have received the invite.
Let us know if you have questions.
Thanks for posting!
Thank you Rona,
I want to know that "would the recipients of the "ML" have been able to access the invited folder?".
If a recipient other than me can access the invited folder, I think it's a security inciden !
