I receive an UnauthorizedAccessException when trying to upload and replace a file in File Manager.
The ApplicationPool user has full access to the files and folders, and the logged in EPiServer-user has full access. I can create new files, delete old, rename etc - but I cannot replace files.
[UnauthorizedAccessException: Access to the path '\\server\share$\MySite\Global\File.pdf' is denied.]

Probably application pool has full access rights for VPP folders and files that where created by application, but it does not have write access to files that where not created by application (for example, when files where uploaded during site deployment).
Could you check if application pool identity account has full access rights (or at least write) for that specific file?
