It's easy to attach pictures, files, and other items to your Outlook messages. Outlook keeps track of the documents you’ve recently worked on, whether they're stored on your computer or saved in OneDrive (cloud only). And no matter where they're stored, Outlook lets you quickly choose whether to send the document as a traditional attachment or upload it to OneDrive and share a link to the file. You can also set permissions on any file sent from OneDrive that allow message recipients to view and edit them or share them with others.

Select a tab option below for the version of Outlook you're using. What version of Outlook do I have?

Note: If the steps under this New Outlook tab don't work, you may not be using new Outlook yet. Select Classic Outlook and follow those steps instead.

In new Outlook, you have the option to:

Attach a file  |  Upload a locally saved file to your OneDrive  |  Show a picture in the body of a message  |  Attach an email  

Attach a file to an email message in new Outlook

New Outlook keeps track of the files you have worked on recently and suggests them whenever you decide you want to attach a file to an email message. Some file types are blocked from being sent or received. See Blocked attachments in Outlook for the complete list.

  1. In a new message, a reply, or a forwarding message, select Attach File from the Insert group on the Message tab.

    Tip: You'll only see Insert group on the ribbon when you select New mail, or after you select Reply, Reply all, or Forward on a received message.

  2. Select your file from one of the following locations:

    • Suggested files The three most recent cloud files you've worked on will be displayed here. These files may be on OneDrive, SharePoint, or another online document library. Select a file to attach to your email.

    • OneDrive Locations include OneDrive, SharePoint sites, or connected third-party cloud storage providers. Select one of the locations to open a new window and then select your attachment.

    • Browse This Computer Opens a File Explorer window where you can choose a file from your computer.

  3. If you select a file on your local computer or group document library, a copy of the file is attached to the email. Selecting a OneDrive or SharePoint file, however, provides you with additional permission options and information. 

  4. Send a link or send a copy: Sending a link to the OneDrive or SharePoint file keeps the size of your email message small. If you choose to send a copy of the file, the entire file is attached to the email, just like it would be if you selected a file on your computer. If you choose to send a link to the file, you can also set the permissions on your file.

  5. By default, if you're in a business environment, everyone within your organization can edit the linked file. To change these permissions, select the arrow at the right of the attachment name to display a drop-down menu with a variety of permission options.new Outlook attachment permissions window

    • Organization can Edit: if you want anyone in your organization to be able to modify the file. They will also be allowed to share the item with others.

    • Organization can View: if you want anyone in your organization to be able to read, but not modify, the file. They will not be allowed to share the item with others.

    • Recipients can Edit: if you want only the recipients of your email to be able to modify the file. They will also be allowed to share the item with others.

    • Recipients can View: if you want only the recipients of your email to be able to read, but not modify, the file. They won't be able to edit or share the file with others. To learn more, visit Sharing files, folders, and list items.

  6. If new Outlook detects that your recipients won't be able to view the file, for example, if it's stored on a SharePoint site that's only accessible to you, you'll see the link highlighted in red with a warning icon next to it. Select Manage access to resolve the warning message. You can also manage permissions by selecting the arrow.

    Note: If you attach a file as a copy, any changes your recipient makes won't be synchronized with the version of the file in OneDrive or on SharePoint.

Warning about forgotten attachments 

If you mention an attachment in your email message but don’t include it before sending the message, new Outlook will display a warning about the forgotten attachment. You can then decide to add an attachment or send the message without one.

Tips for sending and receiving file attachments

  • If you reply to a message that has an attachment, the attachment won’t be included in the reply.

  • Don't open an attachment sent in an email message unless you trust the content and the person who sent it to you. Attachments are a common method for spreading computer viruses. 

  • Long file names of attachments might be shortened in Outlook on the web. This won’t affect the contents of the file.

  • You can only attach files to calendar events that you or a delegate created.

  • In addition to restricting the size of individual messages, some email systems put a cap on the total size of your mailbox. Since each message you send is stored in your Sent Items folder, reducing the size of attachments can also help keep your mailbox size small.
