Dear @Caleb Jenkins
I understand the issue. If your colleague can open the file from a direct link but cannot see the document library when browsing the SharePoint site, the most likely cause is that they have permission to the specific file but not to the library itself.
I recommend checking the following:
- Go to the affected document library > Settings > Library settings > Permissions for this document library.
- Check whether the library has unique permissions or whether permission inheritance has been broken.
- Verify that your colleague (or a group they belong to) has at least Read permission on the library/site.
- Also check the file’s Manage access settings to see whether the user was shared the file directly.
If the file was shared directly, SharePoint can automatically grant Limited Access to the surrounding site/library so the user can open that specific file, without granting access to the rest of the library. Please refer to this document: Permission levels in SharePoint
If you want the user to browse the library normally, I would grant them appropriate permission at the library or site level, rather than only sharing the individual file.
