how to edit appointment created by dragging Outlook 2007 email?

[SandraNoble]

Just loaded Office 2007 on XP. In prior versions, I could create an
appointment by dragging an email message to my calendar. That still works.
The problem is that once I've done that in the appointment, I can no longer
change or edit any of the text from the original email message. I can add
data around it. For example, I cannot copy the event location from the body
of the appointment and past into the location.

Is it perhaps HTML or something as an image. It works ok here with text.
