Top free vSphere tools of 2012: Veeam, vKernel, Xangati make the list

Although Veeam Explorer for Exchange is currently in beta, it's worth a mention because the tool will allow vSphere users to mount Exchange Server backups and browse to the Exchange email database. With Veeam Explorer for Exchange, you can browse mailboxes and search or export items such as email, notes and contacts. It will mount Exchange Server backups created with the first tool on this list, the free version of Veeam Backup.

Honorable mention: Veeam ONE is the latest version of the Veeam Monitor product, but in a free edition.
