Sorry to bother the Mageia forum with these questions. There are a lot of answers in the Evolution FAQ publication.
I include the following only for the sake of completeness. (It comes from the
Evolution FAQ publication).
The link may be old, but the similar questions and answers have been scattered in the new documentation.
Running evolution under KDE.
*** I upgraded Evolution - where are my icons gone? I only get red crosses...
Make sure that you have installed gnome-icon-theme and hicolor-icon-theme. Also make sure that gnome-settings-daemon is running. If you are using Evolution under KDE, add a line to start the gnome-settings-daemon before startkde in your .xsession file. For Evolution version 2.x also try executing gtk-update-icon-cache from a command line console.
*** Why is my font too small when composing emails in Evolution in KDE?
Make sure you have gnome-control-center and gconf-editor installed. Run gconf-editor and change the following key values:
desktop->gnome->background->draw_background (uncheck)
apps->gnome_settings_daemon->start_screensaver (uncheck)
apps->nautilus->preferences->show_desktop (uncheck)
Perhaps you also have to play around with some GNOME settings like dots per inch, mouse settings, keyboard repeat, etc. to prevent the gnome daemon from changing KDE settings.
Then run "gnome-appearance-properties" (GNOME 2.18 and earlier: "gnome-font-properties") to set your fonts (it will start the settings daemon) Now the final step it to ensure that the gnome-settings-daemon starts up automatically when starting up KDE (the KDE session manager will not do this for you) - or the fonts will be incorrect anyway. Go to $HOME/.kde/Autostart and create a file called gsd.desktop and put the following lines into that file:
[Desktop Entry]
Name=gnome-settings-daemon
Exec=gnome-settings-daemon --oaf-activate-iid=OAFIID:GNOME_SettingsDaemon
Terminal=false
Type=Application
*** Why can Evolution not be started from KDE, but from GNOME
Evolution is a GNOME application and should normally work perfectly under KDE if you have the required GNOME libraries installed. If you start Evolution under KDE from shell/console/terminal prompt/commandline and get errors about QPixmap and QPainter, it is very likely a theme problem. Try to not use gtk-qt, try a different theme under KDE.
*** Where does Evolution store my data?
Evolution stores your data in $HOME/.evolution/, your account settings in $HOME/.gconf/apps/evolution and your passwords in $HOME/.gnome2_private/Evolution. The passwords are not stored encrypted, just base64 encoded. SSL Certificates are stored in $HOME/.camel_certs, and if Evolution crashed while you were writing an email, there could even be a file $HOME/.evolution/.evolution-composer.autosave-123456 (where 123456 is some string). Note: If you run Evolution 2.8 or older, the file will be at $HOME/.evolution-composer.autosave-123456.
Note: If you run Evolution 2.32.0 or later version, ~/.evolution directory will be gone and the files will be partitioned into three base directories which are by default:
$HOME/.local/share/evolution - The user's data files
$HOME/.config/evolution - Various configuration and state files
$HOME/.cache/evolution - Disposable data caches
