You do need Microsoft's Word, Excel or Powerpoint installed so that MS Outlook Express can use the spell checker. OE cannot use Corel's Word Perfect for spelling. OE does not come with a spell checker of its own--not Dell's fault. Open Help in OE and look up spelling. It says: To check the spelling in messages
Outlook Express uses the spelling checker provided with the following Microsoft Office programs: Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. If you do not have one of these programs installed, the Spelling command is not available.
Or you can download spell checker for OE, such as this one
or this one
Note, I am not endorsing these, they are just two examples I found when I googled for 'spell checker for Outlook Express'. Suggest you do that and choose one you fancy.
