Using mapped drives

Hello to everyone!

We are using a folder in a mapped drive, using the UNC path format. But at the moment of creating the output, I get an error: “Cannot use output destination”
Also, I have a folder with pictures that I use for dynamic images. They look good in the preview, but at the moment of creating the output, I get an image with an X (so the pictures are not found inside this drive).

What could be the problem? I tried to search but I didn’t find anything. I checked that the computer has permission to write and read.

Thank you very much for your help!

This look like a user rights issues.
When you are designing, the user under which you are has access to the image folder. When you run through, the service is trying to access it but doesn’t have proper rights.
