Thank guys for your response.. :)
Commercial: -Novell SLOX server soon to be end of life however ( I think they will support it however for 5 years..check with SUSE Novell first however) -Novell Small Business Suite...includes groupwise license for 5 -SUSE Linux Enterprise Server....with additions that you need to add such at Netline (same as SLOX) or OpenGroupware.org
Another thing why they need prefer commercial, they can blame to the vendor or system integrator if something goes wrong :) *aren't we.. * The problem with suse openexchange in my country, it's lack of support, i dont know if there is vendor that can give support for openexchange. :(
Non Commercial - Kolab - OpenGroupware.org
Yes, I know we can use kolab or opengroupware as another solution. But to convince the management, I need a bullet proof tools that can migrate their exchange. Another option is Skyrix with OpenGroupware.
The key element however is the migration strategy and user feature sets that required. If outlook integration is required then the best I have tested to date is the commercial pluggin from Skryix available for OpenGroupware.org
There are other solutions of course but this is a SuSE list..:) Yupe.. still the best solution for suse.. :)
Good luck.
