Preview pane images accessed via UNC on a server in Dropbox are blank.

This is a tough one. We have Dropbox syncing our server files and access those via mapped network drives on workstations. All files stored locally. The problem is images stored on the server in the Dropbox folder will not preview in the windows explorer preview pane. I create a share outside of Dropbox and boom it works. The thing is PDF, DOCX & XLSX preview fine. It's just images (JPG, PNG, BMP, TIFF). Yeah Dropbox doesn't support server OS ok. Server is 2022. We have had this setup since Server 2012 and has been working great for over a decade. Thinking of moving onto something else, no not SharePoint already tried that. We have heaps of data and SharePoint is too expensive. Maybe a NAS. If anyone can think of something I haven't tried that would be awesome. Must be a permissions issue somewhere.

Hi @spinmaker, thanks for contacting us.

As you've mentioned, currently Dropbox doesn't support server OSes, and as such the amount of support we can provide is limited.

Are the files available locally on the device, in order for them to preview?

This will help me to assist further!

Hello and thanks for the reply. Yes preview works locally and when accessing over the network when the folder is not inside Dropbox. I just tested on 2 Windows 11 machines and its the same issue. The preview pane will be blank when images are accessed over a network regardless if its Windows server or Windows 11. it's only images. PDF, Excel and Word Docs are fine. The staff want it working so it's time to find another solution.

For those that may come across this in their travels, I should have mentioned all folders are set to Available offline. I'm chatting to support now and will report.
