This article providers step by step instruction on how to restore individual mail items back to user mailbox in Exchange 2007, Exchange 2010 or Exchange 2013
Scenario: user deleted folder in his mailbox
Let's use for our example following scenario:
User Billy has accidentally deleted his IMPORTANT folder, and by the time he discovered that folder is missing, item has been already purged from Recoverable Items storage container.
Here is screenshot of his original folder
In this scenario, we deleted "IMPORTANT" folder and purge "Deleted Items"
Steps to recover
1. Determine which database hosts user mailbox
We need to find out which mailbox database hosts Billy's mailbox. If your environment uses a single mailbox for all users, skip this step.
Exchange Management Console (EMC)
Recipient Configuration - Add/Remove Columns - Add "Database" field
here we see that Billy's mailbox resides in 2nd Mailbox
Exchange Management Shell (Poweshell)
same step can be achieved by using Poweshell
2. Create "Recovery Storage Group" in Exchange 2007 or "Recovery Database" in Exchange 2010, 2013
In this step, we need to create recovery database, which serves a purpose of temporary storage for our restored mailbox.
Make sure, that disk where you create recovery database, has enough free space to accommodate entire mailbox database. If you production database is 500Gb, you need same amount of space to restore a copy mailbox copy to recovery database
