I have recently received many questions about the differences between Lotus Notes and Microsoft Exchange. Frequently, the tone of these questions indicates that the person wants assurance that Exchange is comparable to Notes in depth and breadth of functionality. To show that this is not the case, I have prepared the table below showing the Microsoft products that would be required to equal the functionality of the single Notes product.
I should point out that presenting the products in this fashion is not a fair comparison, since the Microsoft products exist in relative isolation, requiring a Visual Basic programmer — having knowledge of all the products — to cobble together a solution that would still not be as robust as Notes. Notes' out-of-the-box functionality is remarkable, and Lotus is moving ahead rapidly with further developments. Already, Lotus has announced two new releases of Notes for 1997. This is on top of three Notes releases in 1996, culminating with Notes 4.5 and the renamed Domino server.
The differences in these key products embody the differences in their companies. IBM and Lotus seem committed to make it easy for businesses to integrate communications, collaboration, and commerce in a single, multi-platform, client/server product. Microsoft develops products that are technically sound individually, but demonstrates a surprising lack of vision and focus by failing to provide an easy way for systems professionals in business — versus technicians or hobbyists — to integrate its hodgepodge of products.
Lotus has clearly proven the strength of Notes' architecture by the ease with which Internet protocols were incorporated into the single Notes product. Notes has all the right ingredients for continued success and, coupled with the financial strength, marketing experience, and database expertise of IBM, presents a challenge that will take Microsoft years to answer.
For these products, the familiar saying "You can't compare apples and oranges" should become "You can't compare an apple and some oranges."

As you can see in this update, several of our projects involve Lotus Notes in some way. Not only is Notes an integral part of our internal operations — it has helped us share information and improve our processes, regardless of where we work — but it is also a key part of how we can help companies improve their business processes and systems.
