Multi domain in Exchange Online

Good day together
I need help with my settings in Exchange Online. I manage several customer domains via Exchange Online and host various mailboxes of these companies. Now it is so that in the address book email addresses appear across companies, so that company A also sees the mailboxes of company B in the address book.
How can I prevent this?

Thanks for the help in advance.

Best regards
Christoph
