I have a VBA macro for handling e-mail attachments in Outlook 2007 (based on
the version from Nicola Delfino). The macro saves any attachments in an
e-mail highlighted in the Inbox, then deletes them, and finally adds a line
of text into the original e-mail with the path where the file saves (see code
below). The macro handles the first two tasks fine, but then I receive the
following error when I try to add the text to the message:

Error Number: 4605
Error Description: This method or property is not available because the
document is locked for editing.

This happens when the text is being inserted into the e-mail message. When
I'm debugging the code, I've noticed that many of the WordEditor properties
are locked and unavailable. How do I unlock the underlying Word.Document
properties and add the text?

Thanks!
