Retain 3.5.1 on Windows Server 2012
Retain is not connecting to Exchange after adding a load balancer. A clue was Prime size must be multiple of 64 and can only range from 512 to 1024 (inclusive).
Trying to bypass the load balancer was not successful.
This pointed up to a bug in Java 1.6.
This issue would not occur in Retain 4 as it uses Java 8.
