How to recover Exchange server?

This is using MS Exchange Server 2013 on MS Hyperv VM. This is the only one combined-role Exchange server. This server was found invaded by ramsonware since 5 Oct, and after much investigating, we found that it is quite certain to say that it if beyond repair. There were a daily routine backup using Veeam backup and replication, but we suspect that all the backup images for the past 2 weeks are also encrypted by ramsonware (certain files and folders). Are we able to rebuild the same exchange server by running the exch setup file?

Or else what would be the best way in order to get the exchange server back into operations.

Thanks in advance.

Hi,
If you are sure it is beyond repair copy the EDB file and recover the server using  /M:RecoverServer switch
Create another server with the same name and IP address. reset the computer account in AD.

Hi,
First of all Prevent Ransomware from Executing on your server. There are some certain steps for that. You can go through below given links:
http://blogs.catapultsystems.com/jstocker/archive/2014/06/10/how-to-prevent-ransomware-from-infecting-to-your-enterprise-applications/
https://blogs.mcafee.com/business/security-connected/prevent-ransomware-on-your-servers/

After that you can Execute exchange EDB file recovery command in PowerShell or EMS. If that doesn't seems working then you can try any third party Exchange Database Recovery Tool. Just try their demo version to check whether it is working for you or not. If you find it working very well then you may go for purchasing.
