You can get by with your specs for the small # of users.

I suggest don't take on the support costs.

The listed solutions are all great but I feel you are just to small to put that kind of energy into this solution.

With that few users just use google and it's shared calendar and spend all that saved time on something else. If you really want to use outlook, look for an exchange service where you pay them to host and manage an exchange server for you. If you want everything that exchange does without any headaches stick with exchange. There is no perfect open source solution to replace exchange but rather it just replaces some of the functions.

Outlook calendar works off this package but still connects to something like Citadel or whatever for email?
I set up a simple ftp server with anonymous users being able to write to it and in outlook, I set the free/busy schedule to publish to ftp://ipaddress/user.vfb and made sure the same information was true within the contact in Outlook. That took care of calendar sharing for me.

It'll show you that they are busy or available, but it won't show you what they are doing (like a doctor's appointment or some such thing), so there's still a bit of privacy for the user.

You can also write a quickie vbs script that'll import all the contacts with the free/busy information already in it if you'd like everyone to have the same contacts list.

If you want to know more, let me know and I'll share some code with you.

Opensource alternative to Microsoft Exchange

I have a client that are looking at groupware or MSExchange functionnalities.

They're comfortable with open source software.

They have about 80 users with Outlook used as a pop3 client. They don't have any groupware solution in place right now.

I'm looking for suggestions. I heard about Zimbra, Open-xchange but is they matrix somewhere that compares different open-source groupware solutions ?

I think the main functionnaity they're looking for is shared calendar, web-access maybe.

Both of those options fit that bill. The AJAX web client for Zimbra is very nice and installation is simple.
Took me about 15 minutes to install Zimbra on my Debian box and another 10 to configure it.

@xp_newbie: FC4 hasn't been supported/updated (inc security updates) for a while now. You should think about upgrading ideally...


exchange, groupware, microsoft
