Mail quota settings must not restrict receiving mail.


Overview

Finding ID Version Rule ID IA Controls Severity
V-33591 Exch-1-301 SV-44011r1_rule ECSC-1 Low
Description
Mail quota settings control the maximum sizes of a user’s mailbox and the system’s response if these limits are exceeded. Mailbox data that is not monitored against a quota increases the risk of mail loss due to filled disk space, which can also render the system unavailable. Failure to allow mail receipt may impede users from receiving mission critical data.
