Egroupware is wonderful! Thanks.
The screenshots look great!!! Too bad I can't install the software and try it out, though. The documentation, forums, comments, etc. say that the "eGroupware-egw-pear-xxx" package also needs to be installed and that the file can be found here at SourceForge (under Files). I cleaned my eyeglasses to make sure I wasn't missing something but the file still isn't there. Also, just to be sure, I had another IT professional try to find the file -- no success. Apparently I'm not the only one with this issue, so if anyone can find this elusive file then please share your discovery here or on the EGroupware Community Forum...
Very good groupware by the set of features. Unfortunately I couldn't get the mail module to work in version 14.1 (with a standard setup and installing packages from the source list), always ending up with "emailadmin_imapbase::openConnection (841) ->open connection for Server with profileID:8 failed! Tried to access unknown attribute 'capability'!". That's mission-critical but maybe they manage to fix this issue. I am furthermore missing SyncML which was abandonned after version 1.8. However it is one of the very few solutions that supports CalDAV and CardDAV. One should be prepared to spend quite a time for the configuration. There is no manual, just a (quite minimalistic) setup tutorial. I don't know whether paying customers get some documentation.
