One of the often overlooked features in Exchange 2010 is Single Item Recovery. The ability to recover quickly deleted items, without restoring a database from point in time backup has been present in Exchange for quite a while.
From the End-user’s perspective, you see the same graphical interface and it is easy to assume, that you are dealing with the same plain old Dumpster and Recover Deleted Items in Microsoft Outlook or Outlook Web App. Moreover, the enhanced Dumpster functionality is not enabled out of the box, and nothing in Exchange Management Console suggests about its availability.
In reality, the whole concept about the dumpster has been updated and in Exchange 2010 we get a totally redesigned Dumpster version 2.
In the following Step-by-Step video tutorial, we demonstrate how to enable, configure and use Single Item recovery in Exchange 2010. As you will see, once the Purges and Versions subfolders come into play, we get the so called Immutability in Exchange 2010:
– When the end-user purges an item, it is not removed from the mailbox but simply placed in the Purges subfolder, where it is kept for the specified by us retention period.
– When an item is modified, Copy-on-write protection takes place and a copy of the original item is placed in the Versions subfolder.
– Dumpster content (Recoverable Items Folder) is indexable and we can use Multi-mailbox search to find items based on predefined criteria.
