Details:
Before new mailboxes can be enabled, they must be processed by the Exchange Provisioning task. On a default system, this task will run once a day. On the task properties, you can schedule the task to run twice a day at specific times.
Starting the Task Controller service and archiving task also force a run to process new mailboxes that have been added to provisioning groups.
After Exchange Server mailboxes have been processed by the Provisioning task, they need to be enabled. This can be done automatically, when the Exchange Mailbox task runs, or manually. When an Exchange Server mailbox is enabled, a new archive is created for the mailbox in the vault store specified for the Provisioning Group. An archive has an associated account that is used for billing purposes, and one or more users who can access the information stored in it. To force the Exchange Provisioning task to process mailboxes
1. In the left pane of the Administration Console, expand Enterprise Vault Servers, and then your Enterprise Vault server.
2. Click Tasks.
3. In the right-hand pane, right-click the Exchange Provisioning task and select Properties.
4. Check that the reporting level is as you require. Full reporting will list each mailbox that is processed, the provisioning group, Mailbox and PST policies assigned the user name associated with the mailbox and the action taken. Summary statistics about the task run are included at the end of the report. You can configure the task to generate reports when the task is run in both report or normal mode.
5. In the right-hand pane, right-click the Exchange Provisioning task and select Run now.
6. Select whether you want the task to run in report or normal mode. The task will then start processing the mailboxes in the provisioning groups.
7. If you selected the option for mailboxes to be enabled for archiving automatically, they will be enabled the next time the Exchange Mailbox task runs. If you did not select the option to enable new mailboxes automatically, you must enable them manually.
To enable one or more mailboxes manually
1.In the Administration Console, click 'Enable Mailboxes' in the Tools menu or click the 'Enable Mailboxes for Archiving' icon on the toolbar. The Enable Mailbox wizard starts.
2.Work through the wizard and click 'Help' on any of the wizard screens for further information.
