In the company I'm working at we have our files on a server that we share. When a customer have some edits requested we get an email in our system with the changes required. Me or one of my colleagues dive in to the job and fix the things in InDesign and then send a pdf back to the customer.
This works really great and it's usually small changes here and there in quarterly and annual reports we work with.
But now it seems like the temporary file saved on the server isn't working like it used to.
This morning I jumped in to fix one job that came in the email system and I saved the pdf and sent it to the customer. And a few seconds one of my colleagues said he tried to save a pdf, but it was already saved. So he was working in the InDesign file the same as I was working on it.
This couldn't be done before. InDesign said the file was already open and I guess it's because the temporary file was in the folder while someone was working. Now it doesn't care if the file is open by someone else.
We did a test now (we have contact over Zoom during the Corona), but I opened the file and then my colleague opened the same file with no problem.
This is something that needs to be fixed. Otherwise we need to call each other and ask about every single file before we start working with it.
Something must be wrong here. It used to work fine before.

I hope you understand what the problem is and please let me know if this can be fixed.
