If you are trying to attach a file from SharePoint, rather than OneDrive or your local computer please see How to attach a file from Classic SharePoint to an e-mail in Outlook .

If you want to share a file with someone directly from OneDrive or SharePoint then please see How to Share a File or Folder Directly from SharePoint or OneDrive

In Outlook there are two seperate ways of attaching a file to an email. You can either Share the file with someone or Attach a copy. 

  1. Go into the Mail app in Office 365 and begin to compose a message.
  2. Click the attach button to open the prompt.
  3. This will show your files in your OneDrive with an option to select a local file as well.
  4. Find the file and select the check box next to it
  5. Press Next at the bottom
  6. When you press next, it will prompt you with two choices, either Attach as a OneDrive file (if you select a file on your computer instead it will say Upload and attach as a OneDrive file, this is the same action however it will upload your file to your OneDrive under the Attachments folder before it sends the email) or Attach as copy
    1. Attach as OneDrive file will share the file with your recipients.
    2. Attach as copy will attach a seperate version of the file that the user will be able to edit and it will not affect the original file.
  7. Once you have pressed your choice, it will attach the file. The icon on the file will change depending on your choice in step 6

 Once you have attached a file but chosen the wrong option to attach, you can right click the file and press either Attach as copy or Upload to OneDrive depending on what you need to do.
