Hi Melissa,
Thanks for the updates in the private message.
Given to the situation, the issue may be related to the permissions of your OneDrive for Business library. Please capture the following screenshots:
1.Navigate to your OneDrive for Business library, click the setting gear>Site Settings>Site Permissions>capture a screenshot for the permission list. Normally, we should see
Everyone or Everyone except external users.
2.In the same page, click Access request Settings in the Manage section, make sure the two Allow
options are selected. This may the cause why we only can get restricted links.
3.Retrun to your OneDrive home page, click Return to classic OneDrive in the left bottom of the page>click setting gear>Ribbon:On>Click the LIBRARY tab>Library Settings>Permissions for this document library. Capture a full screenshot of this page. Check if you can see Stop Inheriting Permissions or Delete unique permissions.
Stop Inheriting Permissions means now the library use the same permission as the site level.
Delete unique permissions means now the library has a unique permission list for itself, the users in the Step 1 permission list may don't have the permission in the library level.
4.Navigate to the Bioserve folder, click "…">Share>Shared with>ADVANCED>capture a screenshot for this page. Here is the permission list for the folder.
5.Navigate to another folder (the user who have entire permission for your library but cannot see that folder), use the same method in Step 4 to capture a screenshot for its permission list. Let us know if the test user in this list.
Note: Let us know if the user who you test with in this list. For each step, we can click the
Check Permissions button>enter his account>Check Now to see his permissions. We appreciate you can also share with us his permissions in the 4 steps.
Best regards,
Tim
