"This file has been moved" error when trying to open Excel files in the Dropbox folder
Integration Affected
Microsoft 365 (specifically Excel)
Operating System/Browser (if using the web)
Windows 11
Question or Issue
One of our users started getting errors yesterday when trying to open Excel documents that are stored within the Dropbox folder. The file opens, but brings up the following error:
The file has not been moved, nobody else has this problem currently. It only happens when the file is within the dropbox folder on her computer. If we copy the file to a location outside of dropbox, it's fine.
Searching the internet, it seems people who use Box (which I'm assuming is similar to Dropbox), are starting to have the same problem. It was reported in their community beginning on Nov 25, 2025 and more and more people are replying to it complaining of the same issue. A few different "fixes" were suggested by their IT which did not fix the problem and yesterday they say they have determined that it's a bug related to the latest Seamless Login release from Microsoft. Just throwing this out there in case it helps the issue to be resolved with Dropbox quicker.
So far, only one of our team members is having this issue. Please help.
I contacted Dropbox support and got this as a response.

I found a way to avoid the problem just momentary until we get a solution from Microsoft or Dropbox,
If you open an excel file on the computer all good
If you move the file to any Dropbox folder it show the error again
"This file has been moved"But, if you open the file on Dropbox online, from there to the excel on the web, and from there to the excel on your desktop, on some way it works with no problem and you can save the files good.
the 3 steps to avoid the error
step 1 on your explorer go to the file you need to work and make right button
step 2 open on dropbox.com
step 3 open on excel for web
open on desktop in desktop
The file will let you work normally.
For reopen repeat the same steps.
Let me know if you have another solution please!!!!
I have also started having this issue. Does anyone know if this is causing files not to save correctly across the team?

Hey everyone, we've been looking into this issue and we'd love your help in flagging this to Microsoft if you've been affected. You can do that by:
- Open a Microsoft Office app.
- Click the icon in the top right corner.
- Select "Report a problem."
- Describe your issue and include the hashtag #cspp-dropbox-filename-encoding-error
This will allow Microsoft to search for the exact logs and investigate the issue. As a workaround, you can enable auto-save feature via Options -> Save -> "AutoSave files stored in the Cloud by default in Excel" and that message won't appear, however, it doesn't explain the root cause of the issue.
I was having the same problem. Solved it.
Go to File > Account > Connected Services:
Remove "Dropbox for Teams"
Restart Excel
I'm unsure if Microsoft did another update or what, but my user said everything seems to be working now and she didn't make any changes. It seems to have resolved itself. Sorry I can't help anyone who is still experiencing the same issue.
