Eveloution is not recommended as a e-mail/calender application
connecting to Microsoft Exchange because of three main reasons:
First Microsoft removed WebDAV support in Exchange 2007 launched in
November 2006. Then the OWA Connector in Evolutions lost its ability to
talk Exchange 2007. This talk at GUADEC 2008 explains the situation:

GUADEC-2008-0.2.pdf
Secondly Evolution gets trouble handling Norwegian characters after
received +4000 mails. According to users, Exchange exhausting the memory
usage on the machine when running. Even systems with 1 GB RAM get
sluggish.
Third if you hear Linux-developers advice you on using Evolution in a
corporate setting, you should be aware of the lack of product quality in
an enterprise setting (when you got 600-700 logged on users and +3000
user accounts).
* What to do then?
Don't despair. You got several options:
-- You can replace your expensive MS Exchange install with Zimbra[1].
It cost less to merge to Zimbra than paying licenses for next MS
Exchange release.

-- An other solution is Kolab Groupware Solution which is sponsored by
the German ministry of interior:

-- If you want to use a stable free software client which uses
MS Exchange, you should wait until Openchange is ready:

Openchange addresses the hurdles dealing with the
changing Microsoft interfaces (API's) in newer MS
Exchange versions. That's possible after EU competitive
authorities forced Microsoft to document their API's in
2004. Microsoft delayed the EU ruling, and got an
additional 899 million Euro fine[4] in 2008.
Then the free software community were able to get
the needed documentation to support MS Exchange.

* Openchange are already supporting the PIM client
on KDE, also known as Kontact. As this slides shows
from Linux Conference Australia January 2009:

* Openchange support for Evolution also make good
progress.
Most likely Openchange support for different Linux clients (as Kontact or
Evolution) will be production ready late 2010. Warning. This is a
prediction. It might be earlier or later. Please consult the roadmap:

-- If you insist on using Evolution with MS Exchange, you might do this
as an experiment with a few users. But to prevent disappointments, you
might use the Microsoft web-client if the computer staff at the
municipality insist on using MS Exchange instead of free software
counterparts as Zimbra[1] or Kolab[2]. Zimbra are used in organisations
with 50.000 users. Kolab got installations from 3000 to 300.000 users.
