How to Recover Missing OneDrive Files After Signing In on Mac
Question details
The user needs to recover documents that vanished from OneDrive on a MacBook after being prompted to sign in again.
- Product
- OneDrive
- Device & OS
- Mac
- Scenario
- Re-authenticating a OneDrive account on a MacBook using Microsoft 365 credentials.
- Observed behavior
- Approximately 18 months' worth of uploaded and downloaded documents disappeared completely after completing the new sign-in process.
Verify that you have logged in with the exact same Microsoft account used previously, as logging into a secondary or different account is a common reason files appear missing.
Restore Files from the OneDrive Recycle Bin
The fastest way to recover missing files is to check if they were accidentally moved to the cloud Recycle Bin during the sync process.
Open a web browser on your Mac and log in to your OneDrive account.
Click on 'Recycle bin' located in the left-hand navigation pane of the OneDrive web interface.
Select the missing files or folders you want to recover, then click the 'Restore' button at the top of the page to return them to their original location.
Use the OneDrive Restore Feature
If you have an active Microsoft 365 subscription, you can roll back your entire OneDrive to an earlier point in time before the sign-in issue occurred.
Contact OneDrive Support for Backend Assistance
If the files are completely missing and cannot be restored manually, Microsoft's support team may be able to investigate server-side data.

Frequently Asked Questions
Why did my OneDrive documents disappear after I signed in again on my Mac?
This often happens if you accidentally sign into a different Microsoft account. Alternatively, if a local sync cache was reset during re-authentication, the desktop client might need time to re-download the files from the cloud server.
How long do deleted files stay in the OneDrive Recycle Bin?
For personal Microsoft accounts, files remain in the Recycle Bin for 30 days before being permanently deleted. For work or school accounts, they are retained for 93 days unless the recycle bin reaches its storage limit.
Can Microsoft support guarantee the recovery of my missing files?
No, backend data recovery by support is not guaranteed. If files were permanently deleted beyond the retention window or lost due to a local failure that never synced to the cloud server, they may be unrecoverable.
