Can no longer sync onedrive to a partition on my SSD

Good day Mike, 

Just to gently clarify before going any further, this forum is separate from Microsoft Support. I don’t have the ability to access or investigate individual accounts because this is a user‑to‑user support forum.  

The error "Your OneDrive folder can't be created in the location you selected" usually means OneDrive cannot use the selected folder because of the drive type, permissions, folder configuration, or a sync client issue. Since your other accounts are still working, I recommend testing the steps below with one affected account first. 

Step 1: Check the U: drive 

1/ Open File Explorer > Right click U: and select Properties > Confirm the file system is NTFS. 

2/ Confirm Windows recognizes it as a local fixed drive, not a network drive or removable drive: 

Press Windows key + R. 

• Type diskmgmt.msc and select OK to open Disk Management. 

Locate the volume assigned the drive letter U:. 

Check whether U: appears as a partition on one of the physical disks listed as Disk 0, Disk 1, or another disk number. 

Verify that the disk status is Online and that the U: partition is marked as Healthy. 

If U: appears as a partition on an internal physical disk in Disk Management, Windows recognizes it as a local disk volume. If it doesn't appear there, it may be a mapped network drive or a substituted drive letter. 

3/ Verify there is enough free space. 

4/ Create a folder such as U:\OneDriveTest > Create and delete a text file inside that folder to confirm you have write access. 

Additional information is available in the following resource: Disk Management in Windows | Microsoft Support 

Step 2: Reconnect the affected OneDrive account 

Before proceeding, please make sure there are no unsynced local files in the affected OneDrive folder. 

Select the OneDrive cloud icon > Settings > Settings > Open the Account tab. 

Select the affected work account and choose Unlink this PC. 

Sign in again. 

During setup, select Change location. 

Choose a dedicated folder on U:, for example: U:\OneDrive Company 

Complete the setup and check whether syncing starts.

Step 3: Test a new folder 

If the same error appears: 

Keep the original folder unchanged. 

Create a new empty folder, for example: U:\OneDrive Company New 

Sign in again and select this folder during setup. 

Check whether synchronization starts successfully. 

If the new folder works, the issue is related to the original folder configuration or permissions. 

Step 4: Reset OneDrive 

Please follow the steps outlined in this article: Reset OneDrive | Microsoft Support 

Step 5: Test the default OneDrive location 

As a final check, try syncing the affected account to the default OneDrive location on your system drive. 

If synchronization works there, the account itself is healthy and the issue is specific to the U: drive or its folder configuration.
