How to save a mail into an .eml-file with Outlook?

"None of the solutions worked with Outlook 2016, but there is a workaround using the OWA Webmail interface:

Open the OWA Webmail view to your list of emails
Click the ""New"" -> ""Email message"" button.
Drag the mail you want to export as .eml into the new email body from the sidebar. It will show up as an attachment.
Click the little arrow on the attachment, then ""Download"" in the menu (see screenshot).

You'll get a .eml file called ""eml"" which will contain the full original email including all headers and attachments.

On older (yellow) versions of the OWA web interface Outlook, you can do the following instead:

Create a new email draft
Drag two (2) mails into the draft
Send the email to yourself
Open the email you just sent and click on the ""Download all attachments"" button."

"Send the email to a Hotmail or Outlook.com account
View the Message Source
Save as an .eml file"

"I got this to work in Gmail UI. Select the dropdown menu on the right of reply and select view original. Then copy paste the content into textpad save as filename.eml and select text file.

I havent figured this out in Outlook 2016 though."

"Bit of a drawn out process, but fairly simple:

Open Outlook and Outlook express on your computer.

In Outlook Express:

Select Import > Messages from the File menu.
Select Microsoft Outlook from the dialog box and press Next.
Select the folder (or all) that you want to convert. Press Next.
After importing, press next.
Find the imported folder and highlight all the messages - Drag them to a folder and they will be saved as .eml format.
