Exchange operates with a hidden deleted items folder referred to as the "dumpster." In Exchange 2007, end users can manually purge email in the dumpster, thereby bypassing an organization's legal hold. This was a major legal risk.
Exchange 2010 introduces a new and substantially improved dumpster that fixes this design flaw, and offers additional benefits.
End users can use the dumpster to restore single emails that were deleted by mistake. Here is how it works: When an email is first deleted it moves to the Deleted Item folder. It remains there until the Deleted Item folder is emptied. Next, the deleted email moves into the dumpster where it is held according to a retention policy set by the administrator. Normally the dumpster retention period is set for 30 days, allowing users to change their mind and restore deleted email within that period.
The dumpster retention period can be set for longer periods or an unlimited time, and this is the important benefit to the organization. Organizations that require retention of email for regulatory compliance, for example, can use a dumpster retention period of n years as prescribed by the law. Organizations facing legal discovery can set the dumpster retention to an unlimited period, in effect putting email deletion on hold until the legal case is resolved.
Dumpster retention periods are set on a per-mailbox basis. Thus, if a legal case requires some of a user's email to be retained indefinitely, for example, then all that user's email is retained indefinitely.
Finally, it should be noted that the dumpster has an important role in the new backup strategy adopted from Exchange 2010 onwards. Because Exchange databases are so large, traditional backups and restores have become impractical. Thus, the approach to backup with Exchange is now:
