Go to Active Directory. Go to the properties of the shared mailbox's AD account directly from the OU that it's in.
Go to the Attribute Editor tab of the account.
Find the msExchDelegateListLink attribute and remove any and all users that you don't want to be automapped, from this attribute.
Have the user reboot and reopen Outlook.
You might have to delete and recreate the user's Outlook profile to force the client to let go.
