Help me to find a free Exchange Server File (.edb) Recovery Software

When I am trying to use “Setup /m:RecoverServer” switch in MS Exchange 2016, it throws invalid command error.

 

As an administrator, I know that powerful software like Quest Recovery Manager for Exchange (https://www.quest.com/products/recovery-manager-for-exchange/) or Stellar Exchange Server recovery (https://www.stellarinfo.com/edb-exchange-server-recovery.htm) can recover data from severely damaged .edb database also.

But, Our organization is not ready to allocate the budget for paid tool. Can any suggest freeware? I am also ready to improve Powershell Command skill.
