It's all part of single sign on now...all that ID stuff is managed in the background (the ID is actually part of the public/private key encryption, much like PGP, so that's why it's a lot more secure than Exchange).

And if you're using Notes/Domino just for email, you wasted the company's money. The true strength is custom secure apps that streamline your business...email is just an app.

Perhaps Exchange does have a few advantages...except that along with Exchange almost inevitably comes Microsoft lock-in (Share-point, Office, Windows desktops, Windows servers, and so on and so on). And with Microsoft lock-in comes heavy expense per user, and the benefits of open-source solutions (more secure, way more economical, more customizable) are lost.

Just mentioning this because I think that it is important to look at the whole pie, and not just one piece of what rapidly turns into a huge investment of corporate funds into Microsoft's bank accounts. So, perhaps hiring sysadmins who do not mind working with more economical non-Microsoft solutions could be a smart investment for many companies trying to remain profitable in the current (or any) economic climate.

For example, Kerio Mailserver and Zimbra apparently work pretty well:

Agree with TDR, Domino was a pig to administer when my last firm used it.

Not saying that Exchange is perfect, but a damn sight better than IBM's monster.

With regard to 2010.. I'll be testing it when it goes live, but certainly not rushing to roll it out.

LOL. What planet have you been on for the last few years. Lotus costs a fortune to deploy and has more limited capabilities and higher integration costs. Having to deploy 'ID files' to everyone - ft!

Now that Exchange 2010 supports 500 heavy users PER SATA drive! The last few holdouts who were trying to pretend the extra costs of running Domino were not enough to incur the cost of migration to Exchange won't have a leg to stand on....

The job stats (and lower rates for Domino as everyone ditches it) says it all:

Its still going to be far more expensive and far less reliable, secure and scalable than Domino.

Maybe in another 10 years we'll get there!
