    One of the new features added in Exchange Server 2010 Service Pack 1 was called Shadow Redundancy Promotion.

  • Exchange Log Truncation Failure in a DAG

    Today I visited a client who had noticed that no log files had ever been removed after any backup within Exchange 2010 SP1.

  • Hub Transport Load Balancing

    In Exchange 2010 (not SP1) and Exchange 2007 there was no memory of unavailable transport servers and so the round robin method of load balancing across the hubs in the target delivery site or smarthosts used by connectors sourced to your current server was just that – round robin.
