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 version of Outlook for Windows.

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 for Windows 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 for Windows:

• 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.).

How to save a message as an .eml file

In Outlook on the web (Office 365)

To export an email to the EML format in Outlook on the web (OWA), click the email to open it, then click the ellipsis (three dots) icon in the top right corner and select Download (Fig. 3.). You will be able to save the .eml file on your local drive.
