To perform a restore on this server, you must use Version 15.2 (Build 1118.21) or a later version of Exchange Server.

Hi. I need recovery Exchange 2019 on-premise, but i got error:

To perform a restore on this server, you must use Version 15.2 (Build 1118.21) or a later version of Exchange Server.

But last CU: 15.02.1118.007, We can't do a recovery from a security update, can we?

I think one of the administrators made a mistake in the server registry and now I have problems.

What to do ? Maybe I can change the build version in the schema ? But where is this parameter stored?
