Is it possible that this also affects network shares that are not mounted as drives in Windows? I had a similar issue in the training yesterday but haven't had the time to copy the stack trace..

Yes, the behavior with mapped network drives is very annoying actually (since a while already):

With a given server \\myserver.example.com\some\share mounted on drive letter X:\:

• the Image Reader (Table) will read the image from X:\..., but not from \\myserver...
• the CSV Writer (and other writers) will complain about missing writing permissions a refuse working when trying to write to X:\... but work just fine when writing to \\myserver... (see this forum topic).

If you guys can push a bit on that front, it'd be awesome 🙂

I stumbled over this issue at a workshop here in Heidelberg again. With the IT setup here it was even more confusing since the Desktop folders of users in the computer pool are mapped to a remote location. So people actually thought that they had copied over their files to the local machine while they were just pushing them from one network share to another:
