Several instances make the Exchange Database (EDB) corrupt, and however, there is no reliable manual solution available to recover them. Luckily, few vendors on the internet are providing automated solutions for Exchange Database recovery. One that is preferred and recommended by several organizations and Exchange administrators is Shoviv
Exchange Recovery Manager. I used this tool a few months back to recover my EDB file that got corrupt due to my nonsense.
Honesty I tried a few other tools before picking this, the thing I love about this tool is it is cost-effective and offers a perpetual license. Hence you have to pay once and use the tool anytime to export EDB to Office 365, PST, and Live Exchange. Also, its incremental export and filter option make this tool a more reliable solution to get desired results.
You can use the free version to check the software skills and compatibilities. It is recommended to users utilize the demo version before making any decision.
