I have imported data using Get External Data and then tried to edit it via
Get External Data/Edit Query, but I get a message "This query cannot be
edited by Microsoft Query". I can't understand why I get this message or how
to access the query wizard under these circumstances. I even re-created my
query from scratch in case it was due to anything I added to the file, but I
still get the same message in the newly created query. How can I
re-establish the Query Wizard?
