Is OpenPaas production ready?

I work with a small public administration organization (less than 100 users). I am looking to upgrade our aging Exchange server with something more modern, open and license-less . I have been looking at OpenPaaS and it seems it could actually fit well our needs.

Before investing time in testing I would like to hear of any testimonials, also, does OpenPaasS as an organization offer any kind of paid support ?

Thanks in advance for your time,
