This is an unlinked Dropbox on Mac Sonoma 14.5

ok. so there is no help and fix for this. while this is happening dropbox is charging top dollar for a faulty service. Not right at all. 

Since Dropbox support is entirely useless I took it upon myself to fix the problem.

What worked for me was deleting the unlinked dropbox and reinstalling a dropbox. It had to download everything I had all over again but all is working as it should.

I have been battling this for 2 weeks now.  I am scared to delete the dropbox if I might lose all my files ... but like you have described I am getting the same messages.  It all started because we are all switching to OneDrive, so I had to unlink my computer and then all hell broke loose.  I couldn't reconnect and get the "This is an unlinked dropbox" message and also the ones about the server etc.  I can access my files on the website, but everything locally on my computer I can't copy or paste or move or open.

Hi,
I'm having the same issue. Did you come up with a solution? Thanks, Thomas

Hi Walter 
Did you find a solution to Chiboko issue. I am having the same issue which has rendered my Dropbox folder useless for the past 2 months. Also, all my JPEG file thumbnails no longer show the image so I can't choose images like I used to which again renders all my images useless. Can you please help? Many thanks, Thomas

Hi there Thomas_Breath_Coach - thanks for the nudge.

Can you please clarify your computer's exact OS version and the status and version of the Dropbox desktop app as shown in your menu bar?

Did you install the app with admin privileges in the first place and have you also granted Dropbox full disk access as outlined here? 

I have been having the same troubles over the past 6 months.  Currently Mac OS 15.2 Sequoia and Dropbox v 215.4.7202, the troubles started in Sonoma and with many earlier DB versions.  I have deleted the Dropbox app, tried the recommended Terminal commands, and reinstalled four times.  For over $1,300 a year, I am about ready to pull the plug for my whole work team and go with someone else.  Recommendations? 

Hi Chatterbox - sorry to hear about this. 

When you say you tried the Terminal commands, are you referring to an advanced reinstall or something else? 

Yes, I have tried every different series of steps to delete and re-install Dropbox to two separate Mac computers running Sequoia 15.2.  Neither is working well.    One one, a laptop with limited discs space and with the default sync as online only, I cannot change folders to offline.  I get no left click or cntrl-click Dropbox menu choices (which used to come up in blue) to change the sync setting.  I also, off-and on, get a warning when I try to open a selective sync document that there is a network or server error and I cannot open it.  This resolves sometimes after a reinstall, but pops up again.  I really want to move some folders I use all the time to offline, but I cannot.

On the other machine where all files are also offline, a computer I use to make local backups of the important working files every hour, now control of select sync which once worked is now off.  I get no dropbox commands when I control click or left click a file or folder.  I have been using Dropbox and supporting a dozen Mac and Windows 9 and 10 machines for a decade now and problems are now popping up everywhere.  I support one Windows 10 machine where sync has not been working for over a month.  I have not had time to Teamviewer into this machine or attempt to resolve this problem in person yet.  I need to fix my issues first. 

I see, thanks for the additional information Chatterbox - much appreciated. 

Could you send us a screenshot of the options you get when you right/ctrl-click on the files inside your Dropbox folder and another one, showing the warning you mentioned? Since you've been having issues with this for a while now, have you tried getting in contact with our support team directly for further assistance with account and device specific information?
