Drag and drop WORKS. However, deletes email. Can we fix?

I use the outlook application for my emails. 

I drag the outlook email to chrome cor upload to the web app.

That all works fine.

However, upon doing this, my email moves from inbox/sent to the deleted folder within outlook.

Is there some setting I can change to stop that email being deleted?

We're having the same problem -- seemingly after some system updates (possible outlook/windows updates).

We use a plugin to allow users to drag emails directly into our web application for upload, but this has recently started deleting the email (although upload still works).

(Chrome, Outlook 2016)

Glad it's working. :)

We don't use a plugin here. Which one are you using?

Ours still deletes after a reset.

I assumed everyone needed a plugin to drag/drop directly from Outlook into a web browser, but I guess this is a new feature they added that you've started using?

We wrote our own plugin using "EasyHook", which copies the email to a temporary file to upload from.

I'm having the same problem.

We're using a plugin, but we uninstalled after chrome updated to 76.

Now my emails are being deleted after the drag-and-drop.

Anyone have a solution to this?

I may have found a potential solution. The emails get deleted due to the dropData.action being set as ‘move’. If it’s set to ‘copy’ it seems to resolve the problem. This is based on the Javascript code. I have not tested it. The solution was found here:

https://bugs.chromium.org/p/chromium/issues/detail?id=322605

This is specifically Chromium, so I am unsure how this affects chrome yet. Also... this is now not an issue with outlook, but with chrome/javascript. 

I don't know how to fix the issue as javascript is based on the website rather than the user. I'll keep looking for how to modify the value.

I hope this will help you to resolve your issue or find someone who does!

In my particular application, I set the dropEffect to "copy" in the dragOver event.

Ex:

Angular component

@HostListener("document:dragover", ["$event"]) dragOver(ev: DragEvent): void {

    if (ev && ev.dataTransfer && ev.dataTransfer.dropEffect != "copy") {

        ev.dataTransfer = "copy";

    }

}

You can extrapolate that to a normal javascript function without issue, I think.

Setting dropEffect in any other events didn't seem to have an effect.

Thank you. This fixes the issue, in my case I had something like this.

$(document.body).on('dragover', function (e) {

e.originalEvent.dataTransfer.dropEffect = 'copy'; // 1 line of code fix

e.preventDefault();        

       // whatever

}).on('drop', function (e) {

// whatever

});

That one line just there solves the issue, even having it like that in a chain.
