How to export an email message to the MSG and EML format

Problem:

You would like to save an email as an .eml or .msg file.

Solution:

In this article you will find out about the most common email formats and learn how to export your messages.

About email file formats

MSG is a proprietary file format used by Microsoft to store individual email messages and other single items (tasks, meetings, appointments, contacts, etc.) outside of Outlook. This format is compatible with any Outlook version.

EML is a standard used by a variety of email clients. This format is similar to a text file, and you can open it in any text editor (such as Notepad). This allows you to convert a .txt file into an .eml file if your email client does not export emails directly into .eml. You can use this format to export emails in Office 365 or many other email clients, for example Gmail.

How to save a message from Outlook as an .msg file

There are two ways to save an email as an .msg file if you're using a desktop version of Outlook:

  • On the message list, select an email and drop it to a local folder or desktop. A new MSG file will be created (Fig. 1.).
