Today, we released an updated version of the https://aka.ms/e2013calc. This release focuses on bug fixes with the DAG auto-calculation functionality that was introduced in 8.3, as well as, support for https://blogs.technet.microsoft.com/exchange/2016/03/03/lagged-database-copy-enhancements-in-exchange-server-2016-cu1. 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. For all the other improvements and bug fixes, please review the http://blogs.technet.com/b/exchange/archive/2013/05/24/exchange-2013-server-role-requirements-calculator-release-notes.aspx, or http://gallery.technet.microsoft.com/Exchange-2013-Server-Role-f8a61780 the update directly. As always we welcome feedback and please report any issues you may encounter while using the calculator by emailing strgcalc AT microsoft DOT com.
