I have installed Exchange 2013 CU8 on Windows 2012 in coexistence with Exchange 2007 SP3 Rollup 16 and as soon as I installed the MBX roles (2 servers) the default databases came with Unknown index state.
I have followed this article https://support.microsoft.com/en-us/kb/2807668 and restarted the servers which brought the DB to healthy again but after couple of minutes it fails once again.
Is this a bug on Exchange 2013 CU8 with Windows 2012? Because I already installed it on 2012 R2 and I didn't have this issue.
I would appreciate any suggestions or comments.
