If Google IME Is Set as the Default Input System, Text Entered in Outlook 2007 May Be Committed Unintentionally

For various reasons, after changing my mail client to Microsoft Outlook 2007, I found that text I typed in the message body of Microsoft Outlook 2007 was being committed unintentionally. It appears that ATOK can have a similar symptom. I eventually avoided it as follows, so I am sharing this for my own future reference as well.

1. Start Microsoft Outlook 2007.
2. Choose Tools > Options.
3. On the Mail Format tab, click Editor Options.
4. Under Advanced, click Enter converted text into the document and set it to .
5. Click OK to close the Editor Options dialog box.
6. Click OK to close the Options dialog box.
