If you use both Outlook and OE or WLM, *.eml attachments on messages within OE/LM will open in Outlook and replies will be sent using Outlook.
The Reply and Forward buttons work but the resulting message may be missing the Send button. The registry hack below opens the *.eml files as an Outlook message. I've used this method for years to avoid opening OE when I open eml files in email or on my hard drive. eml files are simple text files and can be opened in Notepad or a web browser, either by changing the extension from eml to txt or HTML, or by changing the file association to Notepad.
