I ran into a strange problem today with a client using Windows XP and Outlook Express. They had to install a new copy of Office 2007 because they lost their certificate of authenticity for their old copy (don't lose those folks). Subsequently, their spell checker in Outlook Express now only uses the French dictionary. Thanks Microsoft!! Once again, fabulous upgrade to the "new" Office 2007.
After some investigation it turns out that the only viable option for Windows XP users using Outlook Express and Office 2007 is to download a free spell checker for Outlook Express. We have been recommending this one for years . Click here to download and install the spell checker and your Outlook Express spell checking errors will be history…unless you are French.
