I can now, reasonably reliably, synchronise between my company exchange account and KDE for calendar and contacts. The only code change I have made is the activesyncd patch in https://bugs.freedesktop.org/show_bug.cgi?id=59265 It works mostly, although sometimes the server insists on a FolderSync. I am currently working on trying to reproduce that reliably so I can implement a fix in activesyncd to do the FolderSync if the server complains. At the moment I haven't worked out what causes the error. Note that if the error occurs, I can force a folder sync using: dbus-send --print-reply \ --dest=org.meego.activesyncd /EasCommon \ org.meego.activesyncd.EasCommon.get_folders \ string:'user@company.com' boolean:true I haven't yet added code to handle folder names so folders have to be set up using folder IDs (determined by looking in activesyncd's cache). I was going to add a Wiki page showing the configuration commands I use, but before doing that I thought I would post them here for comment. Is anything here wrong or unnecessary? # Activesynd setup gconftool --type string -s \ /apps/activesyncd/accounts/user(a)work.com/username workdomain\username gconftool --type string --set \ /apps/activesyncd/accounts/user(a)work.com/serverUri \ https://activesync.work.com/Microsoft-Server-ActiveSync # Contacts folder syncevolution --configure --template none keyring=KDE backend=kde-contacts \ database=akonadi:?collection=17 @KDE-test contacts syncevolution --configure syncURL= username=user(a)work.com \ backend=eas-contacts database=2 dumpData=0 printChanges=0 \ target-config@work-test contacts syncevolution --configure --template none peerIsClient=1 \ syncURL=local://@work-test username= sync=two-way \ work-test@KDE-test contacts # Personal contacts folder syncevolution --configure --template none keyring=KDE backend=kde-contacts \ database=akonadi:?collection=21 @KDE-test personal syncevolution --configure syncURL= username=user(a)work.com \ backend=eas-contacts database=25 dumpData=0 printChanges=0 \ target-config@work-test personal syncevolution --configure --template none peerIsClient=1 \ syncURL=local://@work-test username= sync=two-way \ work-test@KDE-test personal # Calendar folder syncevolution --configure --template none keyring=KDE backend=kde-calendar \ database=akonadi:?collection=19 @KDE-test calendar syncevolution --configure syncURL= username=user(a)work.com \ backend=eas-events database=1 dumpData=0 printChanges=0 \ target-config@work-test calendar syncevolution --configure --template none peerIsClient=1 \ syncURL=local://@work-test username= sync=two-way \ work-test@KDE-test calendar # Sync all three folders syncevolution work-test@KDE-test
