Things I have tried:
- Site is in the trusted zone for intranet sites.
- Cleared client cache.
- Made the user library owner.
- Made the user site owner.
My research seems to suggest that the problem is a permissions issue, I am a little baffled at that because the user is currently set as site owner with full control. Could this be a problem with the user's Active Directory account and the permissions at that level?
I am unsure how to proceed with further diagnostics. Can anyone shed any light on this?
