If you were talking to someone whose organization is considering Microsoft Exchange, what would you say?
How would you rate it and why? Any other tips or advice?
It is a product that is simple to manage, and easy to use.
VNA redundancy has grown in the data, VNA data variability has grown, even in case VNA found the server goes down, and users can still access their email. So basically everything is good. The feature VNA almost as good as having your own Outlook, although it's better VNA.
If you don't really mind the cost then go for Microsoft. You can never go wrong with them, their solutions are very good. They're stable.

One thing I've been doing is, before I deploy it to a production environment, I always create a "lab" where I try it out and make sure everything is working properly.
