    Hi @IniobongNkanga-8038

    As we know, if a user exceeds one of the outbound sending limits as specified in the service limits or in outbound spam policies, the user is restricted from sending email, but they can still receive email. So we could try to modify outbound spam policies to prevent this user from blocking.
