this issue is already known for some months and still isn’t fixed.
I am meanwhile tired and frustrated with this sick behavior and switching to sth that actually works: rclone or https://github.com/abraunegg/onedrive!
Bye
Yes, the onedrive sync problem is ongoing (I am the person who first raised the problem of all local files being deleted when adding a file; removing and reinstalling onedrive accounts did not fix the problem for me).
But, I would not blame insync for this issue. Companies like Microsoft and Apple have been changing their underlying frameworks (there was an abundance of complaints in Apple forums about Apple redoing its cloud storage frameworks), which have made rsync and similar software much more difficult to implement). My guess here is that MS did something without notice and explanation for its cloud storage and has left insync holding the s__ bag. Insync has to essentially reverse engineer what MS did to onedrive to restore functionality.
For me, the solution has been to stop using onedrive for cloud storage and instead look to other options that still play nice with insync.
Tja, I was in my 7days trial period and it worked fine (using OneDrive on Linux Mint) until today. I will wait it until the problem has been solved.Sorry for that. Hope it will be solved soon.
I too just lost my files (locally). I didn’t see an option to remove my OneDrive account (so I can add it back) in the GUI at first but used terminal instead:
insync accounts list
insync accounts remove “email”
Next time I launched it I was able to add my OneDrive right back and resync everything.

Hi @D.B,
Thank you for posting here and sending your feedback about not seeing how to remove your account easily. I’ll raise this as UI/UX feedback as well.
Please let me know if you encounter any issues syncing your files. Thank you!
I seem to be, as of this morning, been a victim of the same issue. InSync is actively removing files left and right from the sync folder, whilst these files remain in OneDrive.
I’ve noticed that under account preferences my “Ignore Rules” list was blank, which definitely seem unintended.
On OneDrive, in the recycle bin, I see a few dozen folders that have been deleted as well. Though these are not nearly all the folders/files that have locally been deleted.
Removing and readding the OneDrive account unfortunately had no effect.
I’ve been using InSync consistenly on this computer for several years, so this is all quite alarming!
@Jonny10 My deepest apologies for being a victim of this serious OneDrive issue!
When you shared that removing and re-adding the account had no effect, did you mean that the files are still being actively removed from your local folder?
Thanks for the reply, Mia.
I had noticed that, after readding the account, a few other folders were also deleted. As if the process simply continued. Strangly enough, there are a lot of folders left but they are all empty.
I’ve left my computer at the “Scanning” stage all night, but it seemed to have stalled. I will try to do the same today. If all goes well InSync should catch up to the fact that the files need to be downloaded from OneDrive.
Hi @Jonny10, thank you for confirming what the behavior is and my apologies once again for the trouble.
Could you send an update on what the status is? Has it progressed, has it remained stalled, etc?
I’ve managed to somewhat resolve the issue.
After scanning completed pretty much all the folders had an orange icon. With folders being present but empty, but not consistently so. I’ve tried to unsync all of them for a clean slate, then try to re-download them from OneDrive. It was an ardious process to took 6 full days to complete.
Unfortunately I seem to have suffered real data loss, ironically the most important documents. Don’t know what Microsoft has pulled here!
The recycle bin on OneDrive is jam packed, so something went awry somewhere. The website only allows for restoring 100 files at a time, so I’m basically going to spend the next few days clicking a button 
Hopefully everything that’s been lost is still there.
We are terribly sorry that you are dealing with this much trouble after what happened. I am working closely with our engineers so we can continue to prioritize this serious OneDrive issue and put it to rest as soon as possible.
Crossing my fingers that your important files can still be restored.
I just experience this HUGE issue… looking for an explanation found this post… I can’t believe this problem has almost a year and NO SOLUTION had been released. I’m a paid user, I’ve been using insync for YEARS, but this is UNACCEPTABLE
@gespadas same experience for me today. I’m very disappointed and wondering what reliable alternatives are out there for syncing OneDrive on Linux 
I experienced the same issue. I am on Ubuntu 24.10 and using the Insync version for Ubuntu 24.10. A few hours ago all of a sudden all my local OneDrive files started disappearing. The solution was to uninstall Insync, completely delete the settings (mv ~/.config/Insync ~/.config/Insync.backup), remove access to Insync from within my OneDrice account, and then reinstall and reconnect to OneDrive. Now everything from OneDrive is being downloaded to my computer again.
