When an email message is dragged directly from outlook desktop app and dropped into the upload control's drop zone on the webpage then the email in the outlook in getting deleted and moved to the deleted items folder.
I search for the issue on other tech forum and found one solution where it mention to define the dataTransfer dropEffect as "copy" in the code but I am confused to exactly where to put this code and which particular event.
Following is the issue resolution claimed on the internet for your reference.
Code: Select all
event.dataTransfer.dropEffect = "copy";
