Outlook BUG - "Resend This Message" doesn't work for .EML files

I seem to have come across a bug with outlook.

I have an email in eml format, message.eml.

In this certain scenario, I want to resend the email using the outlook action Resend This Message

Note: You cannot do this if the email is a .msg, as the option is greyed out

You edit the message as you wish and press Send.

Instantly you will receive an email from outlook (system administrator) saying that the email was undeliverable.

This "email" has no headers, as it is generated locally by outlook. This is it's content.

Your message did not reach some or all of the intended recipients.

  This message could not be sent.
  Try sending the message again later, or contact your network administrator.
  Error is [0x80070005-00000000-00000000].

This only seems to happen with .eml files, I have tested this on multiple systems with different versions of outlook / windows.

It works on Windows 7, Outlook 2007; it doesn't work on Windows 8.1, outlook 2013

Has anyone ever come across this before, and does it happen to you too?

It indeed doesn't work with Outlook 2013... if your EMLs contain From: header (doesn't matter what address is).

To workaround this, just delete From: header from your EML files (using any text editor like Notepad, remove the line that starts with "From: "). When resending them, you'll get additional warning but it will work!

Another workaround is to select the same account in From field on Outlook message's window (yes, just select the same account you're already seeing on message).
