There is no warning given if a user unlocks a file which has been locked by another user.

Currently we have users who are locking files, while they edit content in desktop Office apps, but other users are unlocking as they also have to make urgent changes. This is causing a conflict of edits and loss of changes.

If a user, other then the person that locked a file, unlocks a file then there should be a warning message displayed that asks for confirmation before the unlock is implemented.
