Here at the College of Veterinary Medicine, we currently have: GroupWise 7 running on NetWare OES for ~1,500 users and resources We are in the process of moving this to GroupWise 7 on SLES/OES in an active-active clustered configuration connected to an EMC Fibre Channel SAN. In my defense of GW over Exchange, here are some very important points: - GroupWise is cross-platform for both the server and end user, Exchange 2007 server will only run on Windows 2003 R2 and Outlook is only Windows-based (maybe on Mac too?) - Licensing is much simpler: GroupWise only requires you purchase a license for each user. For Exchange you must an Exchange server license for any server that will run and Exchange service, both a Windows CAL and an Exchange CAL for each user, a license for each user who want to use the full Outlook Client, etc - GroupWise is directory agnostic, while Exchange requires MS AD. - You have the ability to cluster GroupWise (on Linux) for no additional cost. Trying to do this with Exchange will most certainly require purchasing/upgrading licenses and products. -- Stephen Bogdanski Network Support College of Veterinary Medicine Michigan State University >>> On 12/7/2007 at 11:59 AM, <[log in to unmask]> wrote: > Nag- > > > > We are in the process of evaluating and deciding on a new departmental > email system and wondered what everyone else was using. > > > > If you could take a second and quicky reply with what department you are > in, what software you use and what version, and possibly in what > configuration (ie.
