The server is SBS2011 Standard SP1, with Exchange Server 2010 SP1 (22.214.171.124).
Rollup 7-v2 for SP1 and Rollup 8 for SP1 have been applied.
Updates are done every week via Microsoft Update, but SP1 Rollup 8 for Exchange is the most current update that has come down. According to “Exchange Server and Update Rollups Build Numbers”, the most current for Exchange 2010 is “Update Rollup 8-v2 for Exchange Server 2010 SP3 - Build number: 126.96.36.199”.
I have found steps to install SP3, but can “Microsoft Exchange Server 2010 SP3” be applied and then the most current update, or should it be updated in steps (SP2, then SP3)?
