Based on experience at a number of jobs, Exchange may appear to be easy to
configure, but as soon as you get past the utterly basic configuration,
when management or other departments want more, it then becomes a major

I work for a US federal contractor these days, on site (civilian sector)
and they just gave up, and moved to M$ cloud for it. And most people HATE

Searching, if you're not using Outlook, is either terrrible or nonexistant
(they've started auto-archiving here, and I'm hearing there is no search).

In addition, if you go to 365, you are NOT BUYING the software, you're
renting the service. You will be paying every year, and a service contract
will cost, and, presumably, cost more every year.

Linux, once you get over the learning curve, is not that difficult to
administer. and there's a lot of online help (just don't expect us to do
your job for you, as a few folks who've posted here over the years seeem
to expect). You can also get contract help. If that's important, you might
consider upstream, who do provide paid support.

And it will cost a lot less than M$.

I don't know of any mail system that you cannot do that in. Every one
allows that.

Yup. And fixes come a *LOT* faster, often in hours or days, as opposed to
M$'s "there's no probem, it's your fault (insert one week to three
months), ok, ok, we've got a fix

Back in the last century, the old mainframe line was "nobody ever lost
their job by recommending IBM"; since the nineties, it's been
"recommending Windows", because that's all they know. We won't say how
much M$ pays, both for advertising, FUD, and illegal under the table
payments to manufacturers.
