We are three people that work together sharing documents using the cloud service Box. We have no problem sharing documents except when it comes to indesignfiles. It says "Either the file does not exist, you do not have permission, or the file may be in use by another application". This even happens though only one of us have been working with the file. I have been in touch with Box support and after trying many different things they advice me to ask Adobe. How do we solve the problem?
Look for a .idlk file in the same folder and delete it.
