RE: Exchange Server and External Access

["McGill, Lachlan" <mcgilll1 () anz com>]

Think about using an Outlook Web Access server in the DMZ. Make sure it is properly patched and secured!! many white 
papers exist on the Internet that will tell you how to do this.

Hi,

We presently use the Std edition of Exchange 2000 as a mail server for our
internal users, behind the Firewall.

However we would like to grant mailbox access to external users outside the
Firewall.

What would be the most secure and efficient method of accomplishing this. 

One stream of thought that I have been entertaining is having a separate
Exchange/Mail  Server on the DMZ.

Now this solution would result in having to maintain 2 separate mailboxes for
internal and external users. This creates problems for users who would access
their emails from both inside and outside the office.

How can I workaround this problem.

Thanks in advance for any suggestions.

Regards

CP
