Files have a brown box on their icon and dont open in Windows 11

What is going on here? There is no information anywhere so it obviously isnt a problem for everyone.

Most of my files stored on Dropbox now have a small brown file box icon on the lower left corner of the main icon for all MS Office files. They open perfectly well on the phone and a laptop running Windows 10 but not on my laptop running Windows 11.

I get an error message saying the program cant open it because the file is unsupported or may be corrupt.

Why the **** do they release an OS that doesn't work with their own programs??

Please help,

Thanks

I have this problem too and can't find a solution.

I don't know if this will be helpful, but I went to go click on the right-click the dropbox icon in the system tray to check my sync settings, and the icon wasn't there. I realized that dropbox wasn't "running". I started up dropbox, and once it started running, the brown box was replaced by the appropriate dropbox sync icon (grey cloud, closed green circle+white check, open green circle+green check), and I was able to access those files again. I hope this works for you and everyone else who is having this issue because it was driving me crazy that there were absolutely no posted resolutions to the issue anywhere online.

This is EXACTLY what the problem is. It's a Dropbox issue, as far as it seems. Once I fired up Dropbox, my ugly brown file box overlay disappeared and was replaced with a cloud. All of my files can now be opened just fine.

Thanks for the help, everyone!!

It is not a Drop Box issue for me as I dont use Drop Box, however it does appear to be a syncing issue with one drive and either Windows 11 and/or the Microsoft Office version ( full ownership vs 365) - I continue to be amazed that no one from Microsoft has commented or inquired or anything. Dumbfounding.

It's specific to the cloud storage provider on windows 11- they changed how the custom overlays are managed or applied - they also changed the default icon that indicates offline. (It was a black clock in older versions).

If you use the 'save space' or 'online only' option, you are only syncing a shortcut to the file - you'll either see the offline overlay icon provided by the service (a cloud for OneDrive) or the ugly brown windows offline icon. You may only see the ugly icon if you are signed out of the service, have it paused, or are disconnected from the internet.

That makes sense, Powella1 and Diane. I just still find it hard to believe that even that bit of information isn’t available to help someone with this issue. I’ve seen online questions about the brown boxes dating back to 2021 and no answers or information has ever been provided that is anywhere close to being as helpful as what you’ve just explained.

This isn't the first weird problem that the affected users needed to figure out on their own and it won't be the last. :)
