/mcpDisabling and Re-Enabling a Mailbox Store Each mailbox store is automatically disabled when you take the backup of that mailbox store using Disaster Recovery System. When a mailbox store is disabled: • You cannot create a new mailbox in the store. • You cannot move existing mailboxes into or out of the store. • New messages for users with mailboxes that are in the disabled store are queued for delivery until the store is re-enabled. Cisco Unity Connection Administration provides an option to manually disable a mailbox store but you should not disable a mailbox store that is in use. Step 1 In Cisco Unity Connection Administration, expand Message Storage and select Mailbox Stores. Step 2 On the Search Mailbox Stores page, select the mailbox store that you want to disable. Step 3 To disable a mailbox store: On the Edit Mailbox Store page, uncheck the Mounted check box and select Save. Step 4 To re-enable a mailbox store: On the Edit Mailbox Store page, check the Mounted check box and select Save. Controlling the Size of Mailboxes You can specify mailbox size quotas and change the message aging policy in Cisco Unity Connection Administration to control the size of the user voice mailboxes. Mailbox Size Quotas To help control the size of the user voice mailboxes, Unity Connection allows you to specify quotas or limits on the maximum size of voice mailbox. You can configure quotas so that Unity Connection: • Issues a warning when a mailbox reaches a specified size. • Prevents a user from sending messages when the mailbox reaches the limit. • Prevents a user from sending or receiving messages when the mailbox reaches the limit. By default, Unity Connection is configured with the system-wide mailbox size quotas listed in below Table . However, to handle the varying needs of users in your organization, you can override the system-wide quotas for individual mailboxes and for user templates.
