Configure Deleted Item Retention and Recoverable Items Quotas

 

Applies to: Exchange Server 2010 SP2

Topic Last Modified: 2012-12-11

When a user deletes items from the Deleted Items default folder by using the Delete, Shift+Delete, or Empty Deleted Items Folder actions, the items are moved to the Recoverable Items\Deletions folder. The duration that deleted items remain in this folder is based on the deleted item retention settings configured for the mailbox database or the mailbox. By default, a mailbox database is configured to retain deleted items for 14 days, and the recoverable items warning quota and recoverable items quota are set to 20 gigabytes (GB) and 30 GB respectively.

noteNote:
Before the retention time for deleted items elapses, Microsoft Outlook and Microsoft Office Outlook Web App users can recover deleted items by using the Recover Deleted Items feature. To learn more about these features, see the "Recover deleted items" topic for Outlook or Outlook Web App.

You can use the Shell to configure deleted item retention settings and recoverable items quotas for a mailbox or mailbox database. Deleted item retention settings are ignored when a mailbox is placed on In-Place Hold or litigation hold.

To learn more about deleted item retention, the Recoverable Items folder, In-Place Hold, and litigation hold, see Recoverable Items Folder.

Use the EAC to configure deleted item retention for a mailbox

  1. Navigate to Recipients > Mailboxes.
  2. In the list view, select a mailbox, and then click Edit Edit Icon.
  3. On the mailbox property page, click Mailbox usage, click More options, and then select one of the following
    • Use the default retention settings from the mailbox database   Use this setting to use the deleted item retention setting that’s configured for the mailbox database.
    • Customize the settings for this mailbox   Use this setting to configure deleted item retention settings for the mailbox.
      Keep deleted items for (days)   This box displays the length of time that deleted items are retained before they’re permanently deleted and can’t be recovered by the user. When the mailbox is created, this value is based on the deleted item retention settings configured for the mailbox database. By default, a mailbox database is configured to retain deleted items for 14 days. The value range for this property is from 0 through 24,855 days.
    • Don’t permanently delete items until the database is backed up   Select this check box to prevent mailboxes and email messages from being deleted until after the mailbox database on which the mailbox is located has been backed up.
