Welcome to 42tools

What do we provide?

Our main product is an Open Source connector for Microsoft Exchange 5.5, 2000, 2003, 2007 and later versions. Our aim is to scratch one of the most annoying itches that the Open Source community have endured. This particular itch has been experienced for almost a decade. The problem that we are addressing is the problem of platform independent access for client applications to Microsoft Exchange from version 5.5 onwards. Our solution to this problem will enable a feature-by-feature compatible Microsoft Outlook replacement for Linux®, Microsoft Windows®, the BSDs or almost any other platform.

How do we do it?

We have developed a CORBA based framework on top of the Messaging Application Programming Interface commonly known as MAPI. Our development framework offers client applications MAPI based access to any MS Exchange server from version 5.5 onwards. We believe that we are providing the Open Source community with a development framework that is superior to any other approach. Our solution is distributed under the GNU General Public License (commonly known as the "GPL") or a commercial license. To traverse firewalls, both internal and external, we provide Lorica, a CORBA firewall conduit, also available under the GPL license.

Why do we do it?

We feel that there is a strong customer need for a non-Microsoft client application with full Exchange integration that is feature-by-feature comparable with Microsoft Outlook. The only technically feasible way to achieve this level of integration is to build a client access framework on top of MAPI. Out strategy is therefore to provide this framework to the Open Source community free of charge under the GPL and to the any commercial entity under a commercial license.

So, what is it?

We call our client access framework Brutus. Please see the FAQ, the developer documentaion or our whitepaper (A4 or US-letter) for further details.
