I have a dead Exchange 2007 SP3 with Rollout update 21 in a 2007-2013 coexistence.
I downloaded an Exchange 2007 SP3 ISO from MS but it is an earlier version.
When running the setup.com /M:recoverserver for exchange 2007, how can I install SP3 with Rollout update 21?
Is it necessary for the ISO being used to be the same version as the original 2007 installation?
In a test environment, having the RU21 update in the update folder caused the install to fail.
Regardless of the RU21 update, the recover server install fails in the test environment. Are there any common causes for a recover server failure?
Thanks!
