EDB Diff for Exchange Server allows to compare two Microsoft® Exchange Server email databases. Mailboxes and items that differentiate these email databases are stored as PST files.
Supported Exchange Server versions: 2007, 2003, 2000 and 5.5
The resulting data is saved into a set of Personal Storage File (.pst) format files in 'Added' (for items present only in newer email database) and 'Removed' (for items present only in older email database) folders. PST files are readable with Outlook or other compatible email client.
