I am in the process of 2010 to 2013 migration and in a co-existence setup, 3:3 CAS & Mailbox roles deployed.

Suddenly the first installed 2013 mailbox server crashed and not booting up.Help me with proper ways that how can we forcefully remove the server and install other MBX server in the setup?

Since it's a 1st installed MBX 2013 server, there are certain operations in exchange admin console are not working and searching this server..like error connecting to server MBX** //administrativegroup/

pl. suggest

Hi Jacky,

As we know that once Exchange Server 2013 installation gets completed, it will create the default mailboxes (Administrator and Discovery Mailbox) and the Arbitration Mailboxes on the default Mailbox Database. If you want to remove the 1st MBX server, you have to move all the default mailboxes which in default mailbox database, but now, the default mailbox database crashed as the same as server crashed.

So, the proper way is that try to recover the server.

Best regards,

Hi Niko,

its completely on a virtualized environment.

When I try for a windows recovery mode, it doesn't discover a windows installation directory.

Do you feel that above sneff's reply will work out to recover with default mailboxes? or

Since I moved only 10 mailboxes to the Exchange 2013 setup, I can reinstall the complete 2013 environment say all 2013 HUB and CAS

Pl. suggest.
