/mcpWhen users delete messages, the deleted messages are not removed from the mailbox store until the next time the Clean Deleted Messages task runs. The task runs every 30 minutes and the schedule for the task cannot be edited. Note Changing the Maximum Size Supported for a Mailbox Store Step 1 In Cisco Unity Connection Administration, expand Message Storage and select Mailbox Stores. Step 2 On the Search Mailbox Store page, select the applicable mailbox store. Step 3 On the Edit Mailbox Store page, change the value in the Maximum Size Before Warning field. (For more information on each field, see Help> This Page). Do not change the value of this field if the mailbox store is already at the maximum size that can be backed up during non-business hours. Note Step 4 Select Save. Backup with Multiple Mailbox Stores The duration of backup depends on the size of a mailbox store. The Disaster Recovery System takes the backup of an entire mailbox store and the corresponding database during a single backup session. The default size of a mailbox store is limited to 15 GB so that the backup can be completed during non business hours. For more information on how to backup the multiple mailbox stores, see the “Backing Up and Restoring Cisco Unity Connection Components” chapter of the Install, Upgrade, and Maintenance Guide, Release 15, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/install_upgrade/guide/b_ 15cuciumg.html Configuring Mailbox Stores Consider the following points when creating, editing, or deleting the mailbox stores: • You can create or edit the settings of one mailbox store at a time. • You cannot delete a mailbox store if: • The mailbox store still contains one or more mailboxes. • The mailbox store is still referenced by one or more user templates. • The administrator is trying to delete the default mailbox store (UnityMbxDb1). Step 1 In Cisco Unity Connection Administration, expand Message Storage and select Mailbox Stores. The Search Mailbox Store page displays the currently configured mailbox stores. A user account without the System Administrator role cannot create a new mailbox store. Note System Administration Guide 111 Message Storage Changing the Maximum Size Supported for a Mailbox Store
