Cannot open MSG-file

I’m trying to open an msg-file I’ve received but Outlook cannot open it. When I try I get “Unable to read the item”.
How can I open it?

It sounds like the message has been stored in the new Unicode format and you are using Outlook 2002 or previous. These versions of Outlook do not support the Unicode format but only the ANSI format.

To be able to open it you must ask the sender to send the msg-file again but then save it in ANSI format first before sending it to you.

To change the default msg-format from Unicode to ANSI format, when dragging and dropping an email out of Outlook 2003 or Outlook 2007 into an Explorer folder you must change the following option;

Tools-> Options…-> tab Other-> button Advanced Options…-> option: Use Unicode Message Format when saving messages
