MS Exchange 2007 vs IBM Lotus Domino 8

Postby MSguru » Sun Jan 06, 2008 12:05 am

Hi all,

I have started being regular here. I have been wondering if any one thought of posting a comparison between IBM Lotus Domino 8 & MS Exchange 2007. Both are new and the main e-mail systems products in the market today. I have always been a big Exchange fan, but never tried Domino. I would like to see them apple-to-apple.

Wow! That has to be the most biased comparison of two competing products I have ever seen.

Hi MC_Admin,

Sorry that you think this way of the comparison. We are trying to keep things as unbiased as possible on here. If you can point to what you don't agree with or the points you like to add and you are confident its true please post back with it and we will discuss it and consider adding it if its valid.

Thanks for posting.

Going to have to agree with MC_Admin on this one. This was a heavily biased report. When you look at the feature comarison between Louts vs MS on a purely email basis, there is no comparison.

The report that I want to see is a report taking the day to day business functions and breaking out what the two systems can do. For example, who has the best calendar system. Those are the types of things that my users care about the most.

I have to disagree with MC_Admin & Archaic_admin. Or let's say have a different point of view. I have been working with Exchange since 5.5 and with Lotus since Version 6. Both have their own good and bads.

IBM Lotus Domino is a full messaging solution, where Exchange is mainly and e-mail system as even mentioned by MC_Admin & Archaic_Admin arguments. Thought it will be really unfair if you compare Lotus with Exchange only for features offered by Exchange and ignore all the extra features offered by Domino. For the Business & IT People the return of investment is very important. Its very important how much would you get for what you paid.

In addition, I have noticed most companies which uses exchange their management is not happy about the relative stability their administrators are reaching even with their administrators are working as twice as hard as Domino. In domino, most of the administrators time is spend in developing more usages of it instead of maintaining it. It offer all in one package. In the other hand, I can't deny that MS Exchange offer many whistles that the end users love. So the comparison can be fair if we are looking for a full solution and at the bigger picture, but a more detailed one comparing only e-mail functionality will be good if that all you are planning to use the system for.

How is this biased?

This isn't biased, those are plain facts. If you're going to accuse the authors of bias, at least detail your reasons for saying so, thereby giving them an opportunity to reply.

I'm a Domino Admin of 13 years experience and I admit I don;t know much about Exchange, and so I would love to hear some reasons from Exchange admins on why they think Exchange is better. Even on a purely email vs email platform, if that's what they'd prefer.

Here's some things I have heard about Exchange so feel free to rebuke if you can:

The jet-based data store is not designed to grow into the hundreds of gigs as commonly seen in modern corporate email systems. As a result, there are only two kinds of Exchange Administrators - the kind who have experienced data loss and the kind who soon will. I am sorry, but in todays corporate environment where compliance is often very important, you cannot afford to base your email system on a server that has such a reputation of being this unreliable.

We all know that Outlook/Exchange is far more prone to virus attacks than Notes/Domino. Apparently Exchange has more flexible anti-spam controls but Domino has good enough, and if you use a service such as messagelabs or mailcontrol you don't need that anyway.

You have to take the server off-line to backup the data store. I wouldn;t have thought this was true with open file backup clients so can someone tell me?

In my current job, we have a target of 99.9% server uptime during production hours - not including any scheduled maintenance/upgrades. I am sure that would be impossible to meet under Exchange but we do it easily. We cover Australia and New Zealand which includes several time zones so production hours is 13 hours per day. That allows for about 4 minutes downtime per server per week.

To my knowledge, the one thing MS does better, other than marketing, is integration, especially if your company is using microsoft desktops. Having the lions share of the market, 3rd party applications such as document management systems tend to build their integration into Exchange first and Domino is done almost as an afterthought. Having said that, if you are a SAP house do some reading on an upcoming product called Atlantic.

Hello MR Mc_admin,

I working on Exhcange from last 6 years.

I do;nt know much about Lotus but in your comparasion you have mentioned

"Exchange 2007 require newer 64-bit hardware and more servers (at least 6 server in case of redundancy) where Lotus Domino can reach full redundancy with two servers only, this is due to the new roles Exchange 2007 came up with. "

This is not true , as you can get the redundancy by implimenting only 2 servers in Exchange 2k7 instead of 6 server.

As you can club the rolles which is not recomended by MS but supported.

Take care.........
