Hi, After upgrading from Jessie to Stretch, I would like to redo from start my akonadi configuration. However I do not find how to do this. Worse, launching kontact I get 2 dialogs, first one is "another mailer is running do you want to import from it (but greyes out) and second one is an error message "could not fetch resource" then nothing.
Another problem is I cannot edit the application menu (the right click on the K button gives a menu but the "Edit Applications" entry does nothing. So if someone has an idea how to unblock this, I would be glad
