Thumbnail previews not working after switch from Onedrive Private to Business
In short. After switching to Onedrive for Business (was using a personal Onedrive before), the thumbnail preview in Windows File Explorer stopped working for several filetypes. All files are synced and stored on my harddisk Moving them out of OneDrive makes the thumbnails reappear Before files are uploaded, the thumbnail shows up, but as soon as the file is uploaded and I refresh the folder or have to re-open it later, its showing the application Icon instead of the preview. For STL files, OneDrive replaces the preview created by powertoys with a different color and background. This is assuming it is able to create and the preview is not just the gray background without the 3D-Object. According to my research this is a known bug which exists since at least 2023. Still, I was not able to find any information about Microsoft at least working on a fix. The Thread on Microsoft "Learn" was closed: https://learn.microsoft.com/en-us/answers/questions/5299951/certain-onedrive-thumbnails-not-showing?orderby=newest&page=1&forum=msoffice-all&referrer=answers#answers Filetyps not working so far: Fusion 3D Files *.f3d Stereolytograhpy *.stl (sometimes yes, sometimes not) 3mf mov .CR3 files (Canon RAW files) .... If you are affected as well, please post which file types are not working for you.C0r0nerApr 02, 2026Copper Contributor36Views0likes1CommentOneDrive personal account not signing in 0x800704cf

6h ago my account got hacked by some twerp from Russia. I wasn't quick enough to stop him as he changed my email, alt email, password, removed passkeys, 2FA and whatever else. Even clicking the "this is not me" on the recent sessions didn't do anything. Only one mail was given and that was the one that prompted me that something was wrong (had to check for phising too so lost precious seconds). I got logged out of my account completely and have been doing the same back and forth with microsoft "support" for the past hours. After filling in the Account Escalation form I get a mail stating that all is lost and that i pretty much need to suck it up. 1TB of files (also important ones) just gone? The support chat tells me to keep filling in the form and sending proof that i'm the owner to the email adress given but no reply has come. I need to get in contact with someone who can actually help in order to get my account back. None of the stuff works, the online forms loop me, I can't send codes cuz everything goes to the hackers account. Why can someone from Russia just login on my account and within 3 minutes change everything and there's NOTHING i can do about it? Why isn't anyone truly helping to get my files and account back - cuz everything connected to that account is of course gone too. Posting this from this account since the other one... is unusable for above reasons. I need help, I need all my files back.Mansemat156Mar 29, 2026Copper Contributor16Views0likes0CommentsOneDrive on MacOS Eating Up Huge Amounts of Storage
Hardware: M3 Max MacBook Pro 14" (14 Core CPU/30 Core GPU, 36GB, 1TB) Software: MacOS 26.4 OneDrive Version: 26.002.0105 (Mac App Store version) I use OneDrive to sync files between my PC (primarily used for gaming) and my MacBook Pro (pretty much everything else) mostly because I'm paying for Office 365. I've noticed in the MacOS storage storage section of settings, there's something taking up ~170 GB of storage. Digging around, I found the culprit: Library>Cloud Storage>OneDrive is currently sucking up ~143GB of storage. It seems like OneDrive is keeping large numbers of files stores locally. Legitimately have no idea why this is the way it is, or how to solve the issue (or if there is even a resolution). Like, why bother with files on demand when the application is going to store half the files locally, anyway?jbelack1984Mar 28, 2026Copper Contributor21Views0likes0CommentsNo way of running OneDrive on Windows Server 2019?
I'm running an instance of Windows Server 2019 on Amazon AWS, and need to sync some files. Apparently Windows Server 2019 comes with no traces of OneDrive (even though the OneDrive webpage recognizes my web client as Windows 10 and assures me that it should be installed), so I'm trying to install the app manually. I've downloaded OneDriveSetup.exe (from onedrive.live.com), but the system ignores it when I try to run it, ie. nothing happens... I'm close to tear out my hair, what is happening?SolvedpersonalitysonMar 28, 2026Copper Contributor121KViews0likes16CommentsEnabling OneDrive Health Sync
Hello, once again being victimized by Microsoft 😒 Have a series of users reporting constant sync errors. We've reached out to Microsoft technical support and they just successively told us it was garbage and not to use it. Anyway, trying to get the Sync Health Dashboard to work, based off this document: https://learn.microsoft.com/en-us/sharepoint/sync-health?tabs=windows It's one of those Microsoft documents that the community CAN'T edit, so of course - it's out of date and incorrect. From what I can figure, based on research from other sources, most of this process is now arbitrary, and you have to create a 'EnableSyncAdminReport' in some policy location in the registry. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OneDrive < already exists, but not referenced by documentation Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\OneDrive < key doesn't exist, but is referenced by documentation. but this sorta 'try it and see' methodology really upsets me. Anyone have any insight to this, and why the documentation team fails to update the documentation, or whether this process will work or not?underQualifriedMar 26, 2026Brass Contributor41Views0likes0CommentsFiles not accessible on OneDrive app
My files are not corrupted - if I download them form browser site of onedrive, they can be opened without issues. Nevertheless, my pc folder synced by the OneDrive app, which worked fine until today, became problematic. PDF files show an "access denied" message. Tried logging out and logging in, didn't help.ShadowMarterMar 25, 2026Copper Contributor16Views1like0CommentsShorten local OneDrive path to avoid windows path length limitations
When we set up OneDrive for business, we keep the same local path on every pc: c:\OneDrive Since our company name is quite long, every synced SharePoint will be somthing like: c:\OneDrive\veryveryverylongcompanyname\project_xxxx Currently we are moving some local network drive folders to SharePoint or Outlook Groups and are facing path length conflicts due to the long base path. Any way to shorten your company name without changing it globally?AKIMFMar 24, 2026Iron Contributor54KViews0likes16Comments
