We are experiencing some problems trying to read another users email.

Scenario:
Bob has just been delegated access to user Steves Inbox, Calendar and Tasks
by Steve (himself) adding Bob to the delegate list and granting him
"Reviewer" access.
From his own Outlook, Bob goes to File Open Other Users Folder Steve
(picked from the list)
Bob can now see all Steves Inbox. He can even open some of the Email in
Steves Inbox.
But when he tries to open some email he gets the following message:
"Cant open this item. You do not have sufficient permission to perform this
operation on this object. See the folder contact or your system
administrator"

I cant see any differences between the email he can and cant open.

I have deleted the deleagte and recreated it with permissions - no joy
I have run both users outlook profiles on different PCs - no joy

Anybody seen this before or Any Ideas?

Thanks in Advance
