Splitting database - not a valid file name - shared drive

[jbd83]

Hello
I am trying to split a simple database using the database splitter tool.
I can save the backend locally no problem but when I try to save to a shared drive (on office 365 / sharepoint) I get:
"Not a valid file name"

Any ideas?
Thanks

What is the name you are trying to save it as?

I created a test database with only one table and query - just called database1 and have tried saving the backend with that generated by the database splitter - which is database1_be

The issue comes when I add the file path - using UNC path as suggested in access online help

has the format:
\\ahsnkss-my.sharepoint.com@SSL\personal\firstname_lastname_organisation_onmicrosoft_com\Documents\database1_be
