So, I don't think anyone can call me a 'non linux' guy :)

But are you guys really telling you think the calendaring / scheduling
for individual users and the main corporate account, etc. .. are working
well enough with any Linux solution.

I have researched this very recently and I have not found a solution
that works even reasonably well.

Red Hat has even shifted their calendars to Google .. does anyone think
if an enterprise calendar that really worked was out there they would
not be using it?

I must confess, my servers are FreeBSD, but I'm quite sure the same is 
doable easily on Linux.

We use for calendars Owncloud (may migrate to nextcloud in some future 
to come). That authenticates against LDAP.

For mail we use postfix, dovecot and maia for spam filtering (the last 
harnesses spamassassin, clamav and few other things).

Of course, zimbra you mentioned earlier in the thread (or was it not 
you?), and Kolab provide more corporate-like collaboration environments, 
but I shied away from them as I set myself a goal to give users 
individual handle on spam/virus filtering in email, and neither of them 
has per-user spam preferences (take it with the grain of salt, I might 
have missed something...)

Just my $0.02.

And does that calendar solution allow for things like:

1)  Allowing all users in the organization to see users calendars and
see when they are free to schedule a meeting with them.

2) Allow for designated people to schedule meetings for others (ie, your
secretary/office assistant can schedule meetings for people, etc.)

3) Allow a calendar to schedule shared items .. like meeting rooms,
shared vehicles, etc.  So that people can check those out for specifc
time windows, etc.

Those are just a couple of minor things a lot of solutions can't do

And do they work with imap, etc.  Zimbra does not work very well with
Thunderbird and Lighting (for example) .. many solutions don't work with
Windows or Mac clients, etc.
