Email wouldn't be nearly as valuable if you couldn't attach documents and images. In Outlook 2016, you can click Attach File in the ribbon above any new message screen, or you can use the drag-and-drop method to send files as attachments in Outlook.

When Outlook is running, and you begin with the file visible in Windows Explorer, a new email with that file attached is but one drag-and-drop action away.

Create Attachments via Drag-and-Drop in Outlook

To attach a file swiftly using drag-and-drop in Outlook:

  1. In Windows Explorer, open the folder containing the file you want to attach to an Outlook email.
  2. Open your Inbox in Outlook.
  3. Grab the file from Windows Explorer with your mouse and drop it on your open Inbox.

Microsoft Outlook automatically opens a new email message screen with the file attached. You only need to enter the recipient information and the content of your message before clicking send.

Can I Attach Multiple Files With Drag-and-Drop?

The drag-and-drop method for attaching documents works with multiple files as well. Highlight several documents to select them and then drop them into Outlook to create a new message with all the files attached.

How to Send Links to Documents on a File-Sharing Service

The drag-and-drop method only works with files on your computer, not with files that reside on a file-sharing service. You can send a link to those files, but Outlook doesn't download the document and send it as an attachment. Copy the link and paste it into your email. The email recipient clicks the link to view the attachment.
