Hi everybody!
As a long time user of IBM Lotus Notes i've begin to be curious on Novell GroupWise. In our companies Education License Agreement we also have license on GroupWise, but since we use Notes, GW has not been used.
Because of all strange problems and extremely difficult management of Notes, we are beginning til think on GW.

Latest public release is GW8.0.3, but i've received a Beta-mail about GW 2012 that is out as Public Beta.
To download this Beta i discover that even GW 2012 only runs in 32-bits modes. Will it be a 64bits version of GW? How do GW handle 4000 users? Do GW support HA(Load Balance and High Availability)?
Can we use IBM Tivoli to as backup-solution for GW?
