A Cisco Unity Connection user receives a notification warning that the mailbox is reaching the maximum size allowed. Where can a Cisco Unity Connection admin go to change this setting?

Class of service controls user access privileges and feature restrictions such as maximum message length, but it does not contain storage quota threshold settings.

The Messaging section governs message playback behavior, notification devices, and message aging policies - not the raw storage quota limits that trigger size warnings.

The Mailbox Quotas configuration page in Cisco Unity Connection Administration allows an admin to set the warning quota, send quota, and send-receive quota thresholds that determine when users are notified about mailbox size limits. Adjusting the warning quota value on this page directly controls the point at which the system sends an over-limit warning notification to the mailbox owner.

Contract templates are not a standard configuration object in Cisco Unity Connection Administration and have no role in mailbox quota management.

Disk capacity is a system-level monitoring view showing overall server storage utilization and does not contain per-user quota warning threshold settings.
