Version: 1.12.4 (using 4.3.5 (KDE 4.3.5), Gentoo) Compiler: x86_64-pc-linux-gnu-gcc OS: Linux (x86_64) release 2.6.31-gentoo-r10 So... I have an IMAP server (courier-imap) and more computers. I want the same contacts on all. After a few days of trying to set up KMail's groupware server I came to the following conclusions: 1. KMail is unable to use more root IMAP folders, althoug the UI allows it's creation. The reason could be described here: http://www.courier-mta.org/FAQ.html#namespace 2. KMail is unable to use other folders than the root folders for GroupWare resources (i.e. select MyImap/inbox as groupware folder path). If presented with a folder like MyImapAccount/inbox/MyGroupwareFolder KMail silently fails by not creating necessary subfolders (Contacts, Calendar etc.), which further leads in KAddressBook to a peculiar error about no writable resources being available. Trying to create other root folders is not possible (see 1). I believe the above two are bugs and should be fixed either by (a) allowing subfolders of inbox to be GroupWare containers (b) not allowing users to select subfolders of inbox as groupware root.
I have to add all this succeeded through Disconnected IMAP. Through connected IMAP I was not (yet) able to do anything useful, except crash kmail (apparently if I enter TheIMAPResourceAccount=... it simply crashes - if not, it does nothing). Also, I have chosen the 'deprecated' version (iCal/vCard)
OK, as a workaround, I created a Disconnected IMAP account that connects to the same IMAP server. And it works. However, when the second computer is connected to an IMAP server already having those groupware folders, KMail keeps trying to create those and, quite expectedly, presents me with the failure to do so (since they exist already - duh!)
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
