Stellar Phoenix Mailbox Exchange Recovery literally saved my job as it helped me recover my companys exchange server. The server was showing Dirty Shutdown error due to which the EDB file was not mounting.
I even tried to repair the EDB file using various powershell commands but they yielded no results. After scrambling on the internet for a while, I came across Stellar Phoenix Mailbox Recovery and to my surprise I was able to preview all the mails in the preview pane of the free version so I immediately bought the paid version and then started the recovery process.
The software worked like a charm & successfully recovered Exchange database file. In short, this software is a life saver.
