Hi @Iniobong Nkanga According to your description, I have the following questions to confirm with you：

Is there the same problem when trying to open a file in a web client? Does this user have any error messages when opening files?

To narrow down the problem, I look forward to your kind response. Also, you could check that the Limited-access user permission lockdown mode feature is activated on your OneDrive site. Please follow the steps below to disable this feature：

1. Sign into your OneDrive site.
2. Select the Setting icon in the upper-right corner of the screen.
3. Select OneDrive Settings > More Settings.
4. Under Features and storage, select Site Collection Features.
5. Locate Limited-access user permission lockdown mode, and then select Deactivate.
