Version: 1.11.2 (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages After creating the first account (say "office"), i use "rebuild cache" to sync my existiting mails from kolab server to kmail. After creating the second dimap account (say "home"), and then again using "rebuild cache" to transfer the existing mails from the kolab server to kmail, in the treeview my first account "office" is renamed to "home". So in treeview I have two accounts namend "home", now. The "rebuild cache" for the "real home" works. But every time, when, the renamed "office" account tries to sync with the server, certainly it complains about none existing folders, because kmail tries to sync the "office" folder structure with my "home" account on the kolab server. This bug is reproducable on several client machines. When using only one mail account everything goes fine.
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.
