This is because mounting Exchange Server 2010 on 2016 is not possible and the reason for it is different database structure. The only thing you can do is to install Exchange Server 2010 in the same environment, as Exchange Server 2010 can co-exist with Exchange Server 2016. Only option you have is to create new Exchange Server 2010, but the schema of Active Directory was up to date and modified. This is not the only issue as Exchange Server configuration is wiped out. Thus, users have to create Exchange Server 2016 but they are unable to mount the database once it is restored from backup. Here, you can’t shift the server from one host to another as this is a physical server. Let us suppose that you are working with Exchange Server 2010 and there is some hardware issue. Also, Microsoft will not provide support for Exchange Server 2010 which is near to its end of life. This means when you are using Exchange Server 2010, you will not get any updates.

For example, you have Exchange 2010 installed with you and you are running a program which is out of support. Also, we will clear the reasons behind this task.

Through this illustrative guide, we are explaining the process to mount Exchange 2010 database on Exchange 2016.
