Permissions to email history

[LuckyLouie]

I have created 5 Group Email Accounts, 5 teams Scope Level to email: yes team team team
If the seller of the group "sellers team"corresponds with the customer in Opportiunity is created Opportiunity email history.
Is it possible that the members of the other team could see this "Opportiunity email history" when i assign Opportiunity to this person?
If i changed Scope Level to email to : yes all team team
it works, but eweryone see all emails form all group

It can be done with a workflow with formula in Update Related Records action.
