Mail: Trash box missing
Set up my Vivaldi e-mail account. Sent a test mail from another account, worked well until I tried to remove the test-mail from my inbox: "Error, no trash-folder". Tried to create a trash-folder, worked, but still the same error when I tried to delete the test-mail. Was able to transfer the test-mail to my "new" trash-folder, by using "move to folder", but still unable to delete it from there - same error-message: "no Trash-folder".
Solved: My new Trash folder was originally set up with inbox as parent-folder. Created another Trash-folder with no parent-folder, and from there it worked well - no problem to delete the messages (emtying the Trash-folder).
