I also have the same problem in that Evolution throws the "unknown error" when I try to add an exchange server.
I actually have two exchange servers that I connect to, and the first server I configured worked fine. Server two is at a different location and I suspect is configured differently. I also attempted to run this with exchange-connector-setup-2.8 outside of Evolution, however I had no further success. I went through the various contortions of OWAURL/exchange/username, and domain\username in the authentication fields to no avail. $ rpm -qa | grep evolution evolution-webcal-2.7.1-6 evolution-sharp-0.11.1-10.fc6 evolution-2.8.3-1.fc6 evolution-data-server-1.8.3-3.fc6 evolution-data-server-devel-1.8.3-3.fc6 evolution-connector-2.8.3-1.fc6 beagle-evolution-0.2.13-1.fc6 $ uname -a Linux localhost.localdomain 2.6.19-1.2911.6.5.fc6 #1 SMP Sun Mar 4 16:41:13 EST 2007 i686 athlon i386 GNU/Linux Even so, I may be able to offer some insight. The OWA url I am having problems with is running on https, and it has an incorrect encryption certificate. It is a private site, and is self-signed but I guess they changed the server name a while ago and nobody bothered to update the cert. The page is self-signed to https://foo.company.com/, however the current system is running on https://foo2.company.com. When visiting the site, the browser prompts you to accept the site in its incorrectly signed state. Is it possible that this is a common thread for this problem? If this is a real problem, I can ask the administrators to update the security certificate, but I would rather not waste their time idly. Thanks for your advice!
