A user has given several people delegate access to his mail file.
To prevent some message from being viewed by these delegates, the user created a Private folder and placed these documents there. If the delegate accesses this user's mail file, he does not see the Private folder.
However, if he opens the "All Documents View", the documents that were placed in the Private folder are visible there.
Therefore we request that the "All document" view should not be available for delegates and/or documents placed in private folders should not be visible in the 'All Documents View' by delegates.
