Short answer
Offload means only the connection between the client and the Kemp is encrypted.
Re-encrypted means that the connection between the Kemp and the Exchange server is also encrypted.
 
Basically offload means taking the encryption overhead away from Exchange. In a large environment that can make a significant difference to performance, particularly when all connections use SSL.

If the Kemp was located in a data centre or separate to the Exchange server for some reason, then you may want to re-encrypt the traffic. Same LAN, probably not necessary. Depends on the kind of data you are moving about.

No idea. I haven't deployed a Kemp in over 18 months. I only deploy JetNexus now.
