Re: Hosted Exchange Email

You will need a new, fairly large server. For that number of
mailboxes, DO NOT run Exchange on the same system that is already
doing file & print, unless it is way under utilized and has lots of
free disk space. We also have a separate (small) proxy server outside
the firewall for OWA, so that the email server does not get hit
directly from the outside world.

We have a similar number of users; it takes ~1/2 a person to manage on
an ongoing basis.

I agree with the advice about running on a dedicated box, but you really
don't need a huge server for 160 users.

I've been running Exchange 2003 for 125 users on a Proliant DL360 G5 with
one dual-core Xeon processor (3.2Ghz) for the past 2 years. We've had no
unscheduled downtime at all. Service packs & hotfixes are the only reason
the machine is ever bounced, and that might account for a total of a few
hours per year, at most.

1/2 a person to manage Exchange on an ongoing basis? There's no way that I
spend even ten hours per year on it. I really have no idea what that person
could possible being spending that much time doing with Exchange.
