Moved shortcuts and changed retention categories

Before Enterprise Vault 8.0, an archive did not reflect changes to the location of a shortcut in an Exchange mailbox, or a change to the retention category of an archived item. For example, if a user moved a shortcut to another mailbox folder, the item's location in the archive was still the original folder from which it was archived.

With Enterprise Vault 8.0, when a user moves a shortcut to another folder in an Exchange mailbox or changes an item's retention category, the change is reflected inside the archive.

The main changes are as follows:

* Enterprise Vault Web applications that previously allowed a user to restore to an item's original location now allow the user to restore to the current folder. The current folder is the location in the mailbox that corresponds to the location of the item inside the archive.
* A user can now select one or more folders to search in Exchange Browser Search and Outlook Integrated Search.
* There is a new tab (named Moved Items) in the Exchange Mailbox Policy to control the updating of moved items. You can also control whether the retention category of moved items is updated.
* Shortcut deletion is now performed as part of the archiving process in the scheduled background run of the Exchange Mailbox Task and the Exchange Public Folder Task. Previously, shortcut deletion had its own separate schedule.
* As there is no longer a separate schedule for shortcut deletion, the Shortcut Deletion tabs in the Exchange Mailbox Task Properties and the Exchange Public Folder Task Properties have been removed.
* The Run Now dialog boxes for the Exchange Mailbox Task and the Exchange Public Folder Task now include shortcut processing. There are four Run modes: Archiving and Shortcut processing, Archiving, Shortcut processing, and Report.
* The Exchange Mailbox Task produces a new report file in Archiving and Shortcut processing mode and in Shortcut processing mode. The report shows which folders contained moved items that have been updated.
* Two new audit categories have been added: Archive Folder Updates and Retention Category Updates.
