Smart Sync error - "There was an error opening this document"

[awitzburg]

I can access files on dropbox website, however on all computers utilizing smartsync, every time you try and open a file from the dropbox folder, it says "There was an error opening this doucment. The file cannot be accessed by the system."

I have already tried uninstalling and reinstalling dropbox and the same issue persisted. Same issue accross all computers in my office.

Thanks for the reports, I’ve forwarded this info to our team to conduct an investigation on it as we speak.

I’ll update you here when I receive an update on this matter.

This seems to only have become an issue today after Windows forced an update. I hope there is a resolution soon!

Smart Sync has started refusing to retrieve online only files on demand. The opening app returns an error that the file can't be read or is corrupted. I have to make them local to open the files. We are talking pdfs and word docs so small files. Tried rebooting and I have an internet connection, after all, I'm posting this. Windows Pro 1803 DB client 63.4.102

Same here, though my PC has not recieved any updates recently from MS. I have those delayed out a couple of weeks.

Same issue here with 3 different clients and several computers.

This issue started today December 12. We need a quick resolution.

Thumbnails also do not populate on online only files.

Same here. Proposed workaround does work but obviously is not a solution.

Has this been escalated as level3 incident? This is a Global Wide issue. Apparently is related with a MS Update but is affecting lot of users with SmartSync.

I received a call from another 3 clients with the same issue. We already try disabling AV/Antimalware, same issue.

The only workaround is to right click and select the Smartsync / Local option so the users can download files/folders locally but this can be used only on temporary basis.
