For New Outlook, I can't drag and drop attachment.

I second this request

You are exactly right. And they said it would be available this month and we're still waiting, which doesn't help with the issue.

Hi Mea, just in case I can't find this in their official announcements somewhere, do you have a link for this? I want to follow up with MS Support about this because I'm actually having some users report issues not being able to do this like they can with the current old Outlook, which itself has problems that have since been resolved in the new version, so they're lacking smooth performance in either app.

Haven't heard hide or hare from anyone at MS... The following (so far) has worked for me...

First try turning off "preview" mode (this seems to be where the issue is based from all I've read).

Revert to the "Old" classic view outlook if you are using the "New" outlook revert back (see this post for instructions if needed: https://techcommunity.microsoft.com/t5/outlook/i-need-to-return-to-my-classic-outlook-i-need-to-turn-off-new/m-p/3993858)

Drag and drop worked after turning off preview and restarting outlook.

Interestingly I was able to turn preview back on and it continues to work (i am running the "Old" classic outlook (which is fine, i prefer it to the "new" one anyway.

Hope it works for you.

It's problematic that this change, just like that, can be done when what we have works great and what we're going to doesn't. It's like going from a modern automobile to a Model T horseless carriage.
