In this article, I will show you step by step guide on ‘How to attach an email to another email in Outlook 2019, 2016, 2013, 2010, and Outlook for Microsoft 365? 

Understanding Email Attachments

When we discuss email attachments, we’re referring to files that we send along with our email messages.

These files can range from documents to images, and their inclusion is essential for sharing additional information that can’t be communicated effectively through text alone.


  • What Are They: Attachments are separate files bundled with an email.
  • Common Types: Documents, photos, videos, and spreadsheets are typical.

Email Attachment Tips:

  • Size Limits: Most email providers have a size limit for attachments (commonly around 25MB).
  • Formats: Ensure the recipient can open the file format you’re sending.
  • Security: Scan for viruses before sending attachments to maintain cybersecurity.

Attaching an email within an Email: 

Some email clients allow the act of attaching an entire email as a file to another email. This can be useful for forwarding or preserving the context of a conversation.


  1. Find the Email: Locate the email you want to attach to your mailbox.
  2. Options Menu: Access the options, sometimes denoted by three dots or an ‘Actions’ menu.
  3. Forward as Attachment: Select the option to ‘Forward as Attachment’ or a similarly worded command.

By understanding these elements, we can attach emails or files with confidence, knowing we’ve provided all necessary information to our recipients.

Case Study: As a Project Coordinator in the power sector, my primary responsibility involved compiling daily progress reports from various site offices and sending them to the corporate office. These reports were usually sent via email with an Excel sheet attachment detailing the progress, and the subject line typically read “Progress Report dated <date>.” One day, I received a request to forward the progress reports of the past 15 days for a potential review meeting. Instead of forwarding each email individually, I innovatively compiled all the emails from the last 15 days into a single email with each report attached. This approach not only saved me considerable time but also impressed my seniors with the efficiently compiled information. My skill in compiling project progress was effectively applied to organizing and summarizing the progress emails, demonstrating both resourcefulness and expertise.
