"Your account stopped syncing during an update" error on desktop app on Windows

We have this exact same problem, except I'm not sure how they get to the error windows, ours has been stuck in: 

"Updating Dropbox account..." since the update, no error no nothing, if we try to hit pause it just stays on "Pausing" does not do anything, if we restart its the same deal.

All our servers and every single users laptop is like this, this update literally broke our entire company, we depended on Dropbox for basically all company file collaboration and it has now been stopped dead.

Deleting and uninstalling then re-downloading multiple terabytes on 53 machines is not a solution and if we have to do it, were not doing it on Dropbox anymore.

Whom ever decided this update was a good idea should be fired, I know I'm really close to being fired due to this fiasco, i had planned for the update, just remake all the main IT accounts folders as team folders and move everything back to where it was but this is a whole other level of FUBAR.

You could have left the files as they were and just have all new files from here on follow the new design but this stupidity of force moving MILLIONS of files without an opt in for your customers is shortsighted at best negligent at worst.

Were running a business here, you cannot suddenly force change all folders and files locations without letting us do it manually and slowly, there's applications that point to locations on the Dropbox folder structure, apps that have specific links to file locations on servers moved to other folders and now are failing to backup or log data, throwing all kinds of errors, production servers are stopping because they are "unable to find application path" its a royal effed up train wreck.

Now there's dozens of employees who no longer have access to files, they cant find them  because they have moved, their usual opening excel and clicking on the file no longer works because it moved location, and they are too stupid to understand they have to look for it somewhere else, our ticketing system basically crashed with requests overnight, seriously amateur hour over there guys, who's authorizing your production updates? an 18 year old that never took his it operations 101 class?

I have my entire IT staff currently scrambling for solutions, we have started to download Sync.com and migrating the critical files there and haphazardly restoring what ever semblance of service we can, I had to throw Dropbox under the bus to save my and my whole it staff's jobs, I've pushed for the company to stick with Dropbox for more than a decade, the unlimited space removal was a mortal wound I was trying to recover from, but this is just the final nail in the coffin.

Unless this change is reversed somehow were not going to rework all the machines to stick back on Dropbox, we were already looking for other unlimited alternative solutions, this basically sealed Dropbox's fate.

We were even exited about the upgrade because it was one of the few upgrades where Dropbox added useful functionality instead of useless "added value apps" no one asked for, then they go and do this.

We tried Dropbox, we really did, but you just don't want to help yourself.

Nancy what do you mean "what update"? its THE update, the only update ever on Dropbox history that is so large they had to shutdown service for an hour to perform it, never in our time here (and we've been here since almost day 1) had we seen Dropbox needed to suspend service for an update, it was that big, so there's no way you guys don't know what update were talking about

The problem is simple, Dropbox is trying to move files or folders that are currently in use, and cannot, hence its stuck there, just trying forever to move them, but it cant so service cannot be restored until it does, and again, since it cant, it just stays there stuck forever.

We also cannot see what files its having trouble moving, at least on our side it just stayed stuck on "Updating Dropbox account..." no errors, no messages, no nothing.

Dropbox needs to move what ever files it can, then NOT move the ones it cant, so we can figure out what's causing the problem and manually fix it.

Some of us had our employees windows desktop/documents folders pointing to a folder inside Dropbox, others had production level apps running directly off of the Dropbox folder. 

Any of these could be causing the problem, but we cannot shutdown production servers for a  day just to "find out why dropbox is not syncing"

We need some sort of fix for this, and I'm sad to say we're not the ones being paid to fix it, you guys are.
