Version: (using KDE KDE 3.5.1) Installed from: Debian testing/unstable Packages Well, in older versions of kmail I was able to move a folder from one IMAP account to another, thus enabling me to migrate users from Courier-IMAP to Exchange and vice versa. Suddenly, this is no longer possible.
This was disabled for now because KMail forgot to also move the subfolders of a moved folder. Instead the subfolders were lost (cf. bug 114985). We'll re-enable this again as soon as subfolders will no longer be lost. Due to lack of time this will probably not happen before KDE 4. Maybe moving of folders not containing subfolders will be re-enabled earlier, but for now we chose the easiest solution in order to prevent the above mentioned critical bug.
I've implemented the moving of nested folder a while ago. The code is in KMail in th e3.5 branch, all is needed is to remove the blocking code in kmfoldertree.cpp as shown in the report #114985. See here for details: http://bugs.kde.org/show_bug.cgi?id=114985 http://websvn.kde.org/branches/KDE/3.5/kdepim/kmail/renamejob.cpp?rev=487311&sortby=date&view=log
So what's the status here? I don't think I can move forlders recursively with KDE 3.5.6...
It works for me in KDE 4.3
