You are the Exchange administrator for your company. The Exchange organization contains a single server named Exch1. Exch1 runs Exchange Server 2003 and hosts all user mailboxes.
All remote users access Exch1 by using Microsoft Outlook Express 6. All internal users access Exch1 by using Outlook.
You create several new public folders. All internal users can successfully access the new folders, but some remote users cannot. All users can still access their personal mailboxes.
You need to ensure that all remote users can access the public folders.
What should you do?
A.
Instruct the users who cannot access the folders to re-create their Outlook Express e-mail accounts as IMAP accounts.
B.
Instruct the users who cannot access the folders to establish a VPN connection with the internal network before they open Outlook Express.
C.
Modify the company firewall so that only SMTP, HTTP, and POP3 traffic is allowed to pass to Exch1.
D.
Modify the company firewall so that NNTP is added to the list of protocols allowed to pass to Exch1.
Explanation:
The issue stems from the fact that most of the OE6 clients set up their mail as POP3.
POP3 can be used to retrieve mail, but can’t display such things as calendar or Public Folders.
Changing the clients to use IMAP enables these features.
Incorrect answers:
B:Establish a VPN connection before launching Outlook Express – This will not work,
as the client is still using a protocol (POP3) that can’t Public Folders.
If the clients were to use a VPN connection and Outlook, then this configuration would work, but as stated, the clients will still not see Public Folders.
C:Modify the company Firewall – This will not allow the IMAP traffic through, and hence will prevent all the OW6 clients that are currently working successfully from seeing the public folders,
as well as preventing them from connecting as their connections are set for IMAP, and not HTTP, POP3, or SMTP.
D:Modify the firewall to allow NNTP traffic – NNTP is a news protocol. The Public Folders in question are not using News Groups, so this protocol would have no effect on the problem.
In addition, some remote users can access the folders without incident, so the absence of the protocol in the firewall can’t be causing the problem.
