Hello,
We have a 2010 Environment where the MaxDumpsterTime is set to 4 days and has been for years. We introduced Exchange 2013 recently. When I look at the SafetyNetHoldTime value I see that it is set to 4 days instead of the default 2 days which is my understanding. I know we didn't change the SafetyNetHoldTime value. Is it possible the SafetyNetHoldTime gets the value from MaxDumpsterTime which is odd because they are two different settings for two different versions of Exchange?
