How to Attach An Email in Outlook for Mac [2022 Updated]

Emailing is an excellent way to send someone a message. However, as instant messaging becomes more prevalent, email technology subsequently becomes less relevant. But if there is something emails can do that instant messaging platforms can’t, it’s that you can send large files along with emails. These are what we call attachments since to send large files, you must attach them to the email. Every platform has different methods to send an attachment, but it’s particularly confusing with Outlook’s macOS app. If that’s what you’ve been struggling with, here’s how to attach an email in Outlook for Mac users.

Note: There are a variety of versions of Outlook, so it makes sense that you’d be confused as to what to do to attach a file to your emails. With that said, we’ll take a look at a user guide for each version of Outlook on Mac, starting with the web version.

Part 1: User Guide for Outlook Web App

When someone says they want to attach a file to their email before sending it via Outlook, they typically mean several things.

For one, they might be talking about sending a message as an attachment. They might also only be referring to pictures, or in some cases, the ‘attachment’ they want to send is a document. Depending on the file type, the process will vary.

With that said, let’s first take a look at how to attach an email in Outlook for Mac via the Web app if you’re referring to pictures:

  1. Go to the Outlook website.
  2. On the site, click the blue button at the top-left corner that says New message.
  • The email editor would then appear on the right side of the interface. There, find the icon that looks like a landscape. That icon should correspond to the Insert pictures inline button.
  • Upon clicking the button, a popup window will appear. Simply navigate to the picture you want to attach.
  • Select the picture, then click Open.

With this, you’d have already successfully attached a photo to the email. That’s all you need to do if you want to attach a picture. If you want to attach other file types, like documents or videos, here’s what you need to do, you must follow the exact same steps. The only difference is with step 3. Instead of the Insert pictures inline button, you must click the Attach button which should have a paper clip icon. The icon is located at the top of the email editor as well as at the bottom. Upon clicking the icon, select Browse this computer. At this point, you only have to follow steps 4 to 5 from the previous instructions.

Now, if you plan on attaching a message rather than files like photos or documents, you can easily do so by clicking on an existing message, then pressing Command + R or Ctrl + R to reply to it. That should attach the selected message automatically.

Part 2: User Guide for Outlook 2007, 2010, 2013, And Newer Versions

If you’re using the Outlook desktop app, then you’re either using 2007, 2010, 2013, or newer versions. Thankfully, the steps for all of these versions of Outlook are roughly the same. With that said, here’s how to attach an email in Outlook for Mac:

  1. Open the Microsoft Outlook program.
  2. Click File from the top menu bar.
  3. Select New from the resulting dropdown menu.
  4. Click Mail Message.
  5. Now look for the Message tab.
  6. Under the Message tab, look for the Include section.
  7. Click the Attach button which should be represented by a paperclip icon.
  • A dialog box should then appear. Navigate to the file you want to attach, select it, then click the Insert button.

With this, you can attach any kind of file. The steps for 2010, 2013, and newer versions of Outlook is roughly the same, though there are differences that might make the process a lot more burdensome if you didn’t know. After attaching the files, you should be able to find a list of attachments on your computer somewhere below the Subject section.

If you want a simpler method, then you can also try simply dragging and dropping the file you want to attach to the body of the message. This can work for multiple files as well. Just hold the Command key, then select all the files you want to attach.

That should allow you to select multiple items on your macOS computer. After they’re all selected, just drag them over to the body of the message, then release your left-click button. Now if you happened to attach the wrong file, you can remove the attachment by simply holding the Ctrl or Command key on your keyboard, then selecting the attachments you want to remove. Then, click the Remove button which should be represented by a trash icon.
