My macOS desktop app gives me an incorrect low disk space error message.

I have opened a ticket. Dealing with Dropbox support is beyond frustrating. I’ve never dealt with a company where you are not allowed to speak with someone. Support via email? And when they do respond it’s boiler plate, blame the user nonsense.

HI KJWSr, thanks for the images. I think it would be best to contact the support team since they have more tools and steps available to troubleshoot this matter for you.
You can submit a ticket to the team via this link while logged into your Dropbox account.

Hi - I’m going to send 3 images. The first is the Get info screen you requested. It never gets beyond calculating size. The second is the full Finder screen of the Drop Box folder, note the data info at the bottom. Last image is the Finder screen of the actual drive. Note that Dropbox is the only thing on the drive and also the data info at the bottom.

Thanks!

Thanks for the screenshots, KJWSr! Do you mind right-clicking on your local Dropbox folder as well, and sending me a screenshot of what you see after selecting the "Get info" option?

My Dropbox folder is on a 4TB external SSD. There is nothing else on the drive. The physical drive has 1.19 TB of available space.

My Deskto App is showing that I'm using 4 TB of 4 TB. My online account shows that I'm using 2.76 TB of 4 TB. The online info is correct. The info from the desktop is wrong.

That message isn't referring to the available space in your account. It's referring to the available space on your local hard drive. You're hard drive is full, so Dropbox is not able to sync.
