Same error exporting to existing excel file. Nav 2016 and licensed Excel 2016.
EDIT: seems the error is because the file is in use. Creating a new file with the same name and sheet name gets rid of the error. My guess is because the file takes a long while to open, or because something is corrupt in the file.

First thing you need to check -
Are you using Licensed Version of Excel?
Let me know the Results.
Thanks & Regards,
