Hardware & Software virtualization support

Does not support Virtualization

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* We are not sure what is Microsoft idea of not supporting Exchange 2007 in any type of virtualization at the moment and not even releasing a date when it will be supported. Yes, it might work but won't be supported by Microsoft.

* As Virtualization becoming to be the market trend at the moment due to the fact of it saving money, space, hardware, and easy provisioning it seems a real catch when Microsoft does not support it when exchange 2007 requires a lot more roles and more hardware which could been virtualized and allow good  saving on the hardware cost.

Upgradeability & Integration:

Earlier versions Application Support

               Yes

               Yes

                  No

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* IBM Lotus Domino 8 can do in place upgrade of earlier versions of Domino, where Exchange 2007 can only do a complicated migration of earlier versions. It even requite upgrading Exchange 5.5 to 2000/2003 prior to migration.

* IBM Lotus Domino 8 can integrate with earlier versions of Domino, MS Exchange 2007 can do the same with Exchange 2000/2003, but not with Exchange 5.5.

* Applications written to work with earlier versions of Lotus will most likely work with Lotus Domino 8, where applications written for earlier versions of Exchange will more than likely not work with Exchange 2007 which is a huge waste of investment. 

Solution Type

  Complete Solution

Messaging only       Solution   

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* IBM Lotus Domino 8 offers e-mail, Contacts, Calendaring, team spaces, forums, Integrated IM & Presences awareness, and development tools.

* MS Exchange 2007 only offer a messaging solution and if you need any further functionality you have to pay for an extra product.

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* IBM Lotus Domino 8 has NSF-based composite application that includes both NSF and Eclipse components that offers an easy way to make applications that integrate into Lotus Notes without extensive coding. In the other hand, Microsoft does not offer any equivalent to that.

Clustering Type:

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* IBM Lotus Domino 8 Cluster is on the application level which make it more flexible and give a higher availability than Microsoft Exchange 2007 Cluster which is OS Level cluster and highly dependant on the OS Clustering capability of windows 2003.

Replication Reliability:

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* IBM Lotus Domino has implemented replication for ages to be one of the most reliable and efficient replication methods available.

* MS Exchange 2007 is the first Exchange version to support replication. The replication was not reliable in the RTM release and got a bit better with SP1 but still not the best. In addition, Exchange 2007 replication is not efficient and requires a large amount of dedicated bandwidth which can be expensive.

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* IBM has release Lotus Domino 8 as a solid product fully tested and ready for production, but was a bit late to market.

* Microsoft as usual early to market with half raw product at the RTM version of Exchange 2007 with many bugs and features missing few examples:

Note: these were few of the issues Microsoft fixed with SP1, but even SP1 had its own issues that Microsoft admit in the release note of SP1 and the installation of SP1 has not been smooth for many customers.

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* Microsoft as usual has kept their product maintenance quite time-consuming doing updates for exchange, operating system fixing failures and recovering data stores. It seems they are trying to help administrators look busy to keep their jobs.

* IBM has kept again the Install & Forget approach. After Domino has been installed you only need to visit the box if you need to add or enable a feature. It does not mean administrators will lose their job, but will have an easier life.

Microsoft Office Integration

Yes, but require a free connector

-: IBM Lotus Domino 8 VS MS Exchange 2007 :-

* As Microsoft Office is a Microsoft product which as expected  integrate better with Microsoft Exchange 2007 and without the need for any extra packages, though IBM has released a connector for Lotus Domino that will provide a quite good integration with office. In the other hand, IBM has their own mail Client Lotus Notes which is a great one.

Security:

offers advance security features including: local encryption, digital signatures, Server & user defined level SPAM control, and granular access control.

Although Microsoft has put a lot of effort into building some spam protection and enhancing their security features in Exchange 2007 they still struggle as usual with many security leaks, virus propagation and security holes.
