After contacting support they were not able to resolve my issue, they maintained that it is a network issue on my side. I could not find any answers here or anywhere on the internet and decided to report this issue.
Because I share my processed photos with the rest of the office, my only solution was to un-install V8.3 and go back to V8.2.1, by doing that it resolved my problem.
So yes Adobe you have network issues in V8.3 as version 8.2.1 works perfectly when saving files to a network drive.
This is not a windows issue, since I do only have this problem with Lightroom.
I found a work around, in the export box you can select in the top "select folder later". I you use this, you are allowed to export.
My system: Windows 10, target export folder a mounted folder from a NAS. It is *NOT* an issue with the network folder itself. While LR complained about the "read-only" folder, I could create sub folders and files there as usual.
The export into a local folder worked fine.
After the first error message, I opened the common export dialog and did a "select folder" operation (just to be sure, that the preset has correct settings).
After selecting that folder on my NAS - the export dialog was still open and no export was started yet - I got the "read only" message again.
i am experiencing the same issue.
If I choose a network drive directly on the export path I get the "The specified folder is not writable". However, if I choose a subfolder from where the image is located, even if the image IS in a network folder, then it will allow to export it there.
It appears to happen when the Export folder is in fact a network folder using a UNC path.
All my Export profiles used to work perfectly under 8.2.1
Please address asap.
I too am having this exact same problem since the update. I cannot export images to any folder except my Desktop. It keeps telling me "The specified folder is not writeable"
It worked fine yesterday before the LR Classic update Version 8.3. Once exported to the Desktop, I can cut and paste to any folder (which LR will not export to), but this is not an ideal solution, especially when it worked fine yesterday.
This has really slowed up my production work, so please Adobe, get a fix sorted ASAP. Thanks
Since Lightroom 8.3 writing-access to the office LAN server was denied when trying to export or publish to/on the server. Downgrading back to Lightroom 8.2.1 solved the problem.
Would be great to be informed when the bug is solved.
