Hi, does anyone know of a free outlook exchange server for linux, a bit like openexchange, but free, as I am looking into converting our company server to linux (only about 6 users).

Any info would be great, Buck

Let me ask you this, Is there any features that you would use that can't be solved with a simple mail server such as postfix? Calendar Sharing such? I don't know of any solutions off the top of my head, but if you let us know what your needs are, chances are that there are tons of software out there that can help you out. Maybe just not an all in one solution. Just my 2 cents.

Thanks for the info, the trouble is. I need ALL the features the exchange server provides, and I need it to work *almost* flawlessly with ms office. Running linux on the clients is not an option (I wish it was). Probably the most important features are mail, and calender sharing.

I can do mail by myself I think, but I don't know where to start with Calander Sharing

Actually, Calendar Sharing is quite easy. Simply set up an anonymous FTP server (can be on the same box) with read/write support. Then create a contact within Outlook with the free/busy information (Tools/Options/Calendar Options/Free-Busy Options/Publish at My Location in Outlook 2003) of "ftp://ipaddress/username.vfb" without the quotes. In the Search part of Free/Busy, set it to "ftp://ipaddress/%username%.vfb" without the quotes again. If you want to create a small script for everyone to have the same contact info, here's a simple VB script you can use below: Anyways, when the user goes to invite a person to a meeting, they invite them from the contacts list, and it'll pull up their schedules. It won't show what they are doing, but it will show that they are busy during that time. Hopefully I'm not rambling on too much, but if you have any features that you need, feel free to ask as there's probably a solution for it. Anyways, here's the script below. Just edit to your own needs and save it to a .vbs file extension and run it on the windows client (can be thrown into a startup script if need be) Warning! it will not give you any kind of indicator that it ran sucessfully and such and does not check for the existance of exact users. So in other words, if you run this script 10 times, you'll have 10 contacts with the same information.

' Script To Create an Outlook Contact
' This script will uses COM Automation to access
' the Outlook Object Model in order to create a new
' Contact item.
'
'
' Note that the CreateObject call uses the generic
' reference, "Outlook.Application" with no version
' number. This assures that the script won't break
' just because the client machine doesn't contain
' the correct version of MS Outlook. The script
' will break, however, if no version of Outlook is
' found on the client machine
