Character coding conversion error when using Emacs with Outlook

I'm currently using outlookedit.el to roundtrip e-mails from Outlook in order to remain sane when corresponding with people. It is working beautifully except for when I have to use special characters, in this case "åäö" which are used in swedish.

When I open an e-mail containing these characters in Outlook (C-c o e) they all look ok in Emacs but when I save my changes back to Outlook (C-c o s) "åäö" turns into "åäö" switching back to Emacs (C-c o e) they are converted properly by Emacs into "åäö" again.

If, instead of using outlookedit.el I copy/paste text between Outlook and Emacs character conversion appears to be performed perfectly but I would prefer not to have to do it this way.

I've tried to force Outlook to encode e-mails both into US-ASCII, ISO-8859-1 a开发者_C百科nd UTF-8 under Options -> Mail Format -> International Options... but the result is always the same.

How can I (preferably) modify my .emacs to handle the character conversion properly or reconfigure Outlook to make roundtripping these characters work?

My current Emacs configuration is up for inspection at http://github.com/dholm/dotemacs/.

My guess is that between the Shell, and outlookedit.el, something is happening with your character encoding. You could try setting the default coding system of your buffer to either UTF-8, ASCII, or CP-1252 (The windows default).
