If you want to send pictures or other files in Outlook.com or Outlook on the web, you have three options:

  • Send as an attachment: this is the classic, old-school method.

  • Send pictures inline: add pictures directly to the text in your email.

  • Share from your OneDrive account: perfect for large files, or large numbers of pictures. Your recipient receives a link to only the files you want to share in your OneDrive.

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. We recommend that you use the Preview option if it's available.

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