I thought you were describing Gmail/Google there...

Works better though

> I'd suggest the even more pertinent question to ask is: Who still voluntarily uses Outlook?

In corporate environment Exchange/Outlook is an awesome tool for e-mail, instant messaging, calendar, contacts, booking resources, etc.

I hope you're not referring to Microsoft Lync as "an awesome tool for IM", because I must disagree with you on that if you are.

I had to use Lync at my last job and to be honest it was one of the contributing factors to my leaving.

It breaks links, it breaks basic copy/paste functionality in clear and obvious ways, it wastes screen real estate like its going out of style, it's slow clunky and cumbersome... No Thankyou.

I agree Lync has its drawbacks, but still is pretty useful in terms of sharing desktop, integration with calendar, etc.

Pretty much any Exchange shop that's standardized on Microsoft's tools. There are a lot of them out there.

Probably a sizable chunk of fortunate 500s.

A lot are using Zimbra now days. My company made the switch a few years back.

Lower TCO, has all the same features of Exchange (plus some collaboration features Exchange lacks), plus it's open source so you can hack on it or make your own custom modules if you desire.

It integrates with windows and other microsoft services a lot more closely than thunderbird.

The Bat! Is what I used on Windows back in the days .. nostalgia

I do. It's nice. Super fast for power users compared to web mail apps, and probably the best native client for Windows in terms of functionality. I'm not even locked into Exchange.

Best email/calendar/contacts integration?
