Hi Neil, 

Welcome to Box Community and happy to assist! 

To help you with your collaboration issue, 

• Make sure that you're both looking on the same exact folder. 


• Did you uploaded a new file or edited an existing file? Did you saw the file uploaded/edited without any errors? 


• Are you seeing the file by yourself in the Box website? 


• Lastly, is your collaborator accessing the file through his/her local Box folder or the Box website? Please make it a habit to always check   box.com for the newly uploaded/edited files.
