Oh... right - forgot about that one.
Be careful of Exchange 5.5 as setting it up according to the manual leaves you with an open relay (see slipsticksystems for the how-to to shut the door on the evil spammers). I don't think you
can completely close the relay on exchange 5 and below.
The one feature Outlook has that I want is the ability to "work offline" in the sense that it makes a synchronized copy of the mail store that you can use when not connected. I wonder if there's a way to get Thunderbird to do this. I could just use Outlook - but it pretty much sucks as an email client (other than the "offline" part, that is).
Lotus Notes had this built in from the start (the notion was that it'd support various levels of connectivity and you could adjust synchronization filters to allow for the size and cost of your current bandwidth). Of course, this was back before we all had decent, and fairly cheap bandwidth (before HTML/HTTP, even - although SGML was around as a universal printer markup language).
Might be nice to out-do m'soft on this one...
- although I'm pretty sure the one thing keeping corporate types tied to Outlook is the
calendar. None of the other office suites seem to do this right...
