The first release is Exchange 2010 Service Pack 3. It was talked about back in September that it was ‘coming soon’ and then on the 12th February it was announced as live on the Exchange Team Blog. This update brings many fixes and most importantly allows coexistence with Exchange 2010 and Exchange 2013. Whilst Enterprise Vault 10.0.3 does support Exchange 2013, it does not (yet) have certified support for Exchange 2010 Service Pack 3. So, wait, before installing the service pack!
The second release also announced on 12th February is:
Exchange 2010 SP 2 Update Rollup 6 AND
Exchange 2007 SP 3 Update Rollup 10
Typically Enterprise Vault certification doesn’t go down as far as the individual rollup levels, so, these *should* work and you *can* install them. However, it is strongly advised to test them out yourself on a lab environment which hopefully has many of the same components deployed as your production environment. You might also consider pinging the Enterprise Vault forum on Symantec Connect for feedback before taking the plunge on your production environment.
