I have a user who has two Exchange mailboxes listed in Outlook 2000. She wants to password protect one of the mailboxes so she is prompted for a username and password everytime she tries to expand this mailbox. I know this is possible in Outlook 2003 because their is a tab in the Advanced properties of a mailbox for Security that gives a check box for "Always Prompt for Username and Password." I have started researching this issue, but I am wondering if someone knows how to do this already.
So in summary, whenever my user expands one of her Exchange mailboxes in Outlook 2000 she needs to be prompted for a password.
In the Outlook profile I would tinker with "Services" - "Microsoft Exchange Services" Properites, ADVANCED tab, and at the bottom there is the "Logon Network Security".
On the server side, in ADUC, I would switch to Advanced view, find the person, to the security tab, and remove the Authenticate As for that user. (I haven't tested that, but I bet it would ask for another set of credentials if the above doesn't work.)
