Unfortunately, as a general rule Word and Outlook of different versions do
not work well together.

However, in this case I'm not sure why they should not.

Are you merging to HTML format, plain text or attachment? If you're using
HTML, can you experiment with plain text?

A number of people have reported similar problems even with same-version
copies of WOrd and Outlook recently, but my attempts to get to the bottom of
it haven't got far yet - using Outlook|Detect and Repair seems to do the
business for some people.

The other thing to do is contact Microsoft Support directly, if you have the
retail product and only just installed it. If I experienced the problem
myself, I would do it, but I don't.

If you do find the answer, please post back!
