I'm not sure I understand your question. If I were to save the file locally, then the other computers would not have access. Here's a quick break-down:
Onenote Notebook file (2010-16 file format) resides on local server, mapped to each of the following computers:
Computer 1) Windows 10 (recently updated to Onenote 2016 from 2013)
Computer 2) Windows 8 (recently updated to Onenote 2016 from 2013)
Computers 3-6) Windows 7 Onenote 2010
When we use computers #1 and #2 (both Onenote 2016), it seems everything is operating normally. However, once an edit is made to a specific page, users on computers #3-6 report that particular page as being corrupted.
Yesterday, we upgraded computer #3 to Onenote 2013. It now is behaving like the Onenote 2016 computers in that it no longer reports a corruption, but when it is used to make an edit, all the Onenote 2010 computers report a corruption. Weird, because we've
been using Onenote 2013 and 2010 without any problems for years. Maybe having a Onenote 2016 edit the file changed something??
I need a quick solution, so will be upgrading all computers to either 2013 or 2016 (which version depends on cost).
I hope conveying my problem helps others with this issue!
