Please take a look to the following Diskussion.

Drag and Drop behaviour

I made a rough test with WYSIWYG editor. If a mail is added to Joplin via drag'n'drop in the WYSIWYG editor, the mail is not deleted in Outlook, independently if i use th CTRL key or not. Could the issue, that the mails are deleted in Outlook, base on the "new" MD editor CodeMirror?
