Today, we released an updated version of the Exchange Server Role Requirements Calculator.
This release focuses on bug fixes with the DAG auto-calculation functionality that was introduced in 8.3, as well as, support for ReplayLagMaxDelay.
In addition to allowing you to configure the ReplayLagMaxDelay value (default is 24 hours), the calculator has also been updated to ensure that the SafetyNetThreshold is configured to a value that is equal to or greater than the sum of ReplayLagTime+ReplayLagMaxDelay.
As always we welcome feedback and please report any issues you may encounter while using the calculator by emailing strgcalc AT microsoft DOT com.
