Storage expiry

If you configure storage expiry, the Enterprise Vault Storage service automatically deletes items from archives when their retention periods expire. When the Exchange Mailbox task next runs, it automatically deletes the associated shortcuts from the mailboxes. Similarly, the Exchange Public Folder task deletes the shortcuts that are associated with expired items in public folders.

When certain items such as calendar, task, and meeting items are archived, the original item in the mailbox is not replaced with a shortcut. By default, the archiving task does not delete the original items when it performs shortcut deletion. To include such items in shortcut deletion, configure the registry setting, DeleteNonShortcutItems. The setting is described in the Registry Values manual.

If storage expiry for Exchange Server Archiving is based on archived date, and you have configured Enterprise Vault to archive unexpired calendar, meeting, and task items (that is, items with an end date in the future), then we recommend that you use the advanced Exchange Mailbox policy setting, Future item retention category. This ensures that storage expiry does not delete any archived calendar, meeting, or task items before their end date.

See Future item retention category.

To set up storage expiry

  1. In the left pane of the Administration Console expand the hierarchy until the appropriate vault site is visible.

  2. Right-click the vault site and then, on the shortcut menu, click Properties.

  3. In the Site Properties dialog box, click the Storage Expiry tab.

  4. Select the settings to use, and then click OK.

  5. You do not need to configure shortcut deletion in the Exchange Mailbox policy or Exchange Public Folder policy. The Exchange Mailbox task and Exchange Public Folder task automatically delete expired item shortcuts when they next run.
