Could you please share the following information with us:
1. The pdf files and the output Word file.
2. The OS platform that you are using.
3. The Acrobat dot version you are on.
I have messaged you with the email address you need to share the information at.
Thanks for your patience.
Thank you for your response.
I have sent you the files and the information you requested.
I have now rescanned the original document, duplicated the scan, cropped odd and even pages and combined them in a single 32 page pdf. However, unlike last time I did not re-order the pages. I then output to Word. The first sixteen pages came out ok, but the next 16 did not. So the essence of the problem is not that only alternate pages are output to word. Rather it is that only those pages in the first of the underlying files in the combined pdf are output to Word.
Have mailed you with the workaround.
