Rick,

When the POP3 connector downloads mail for a user (POP3 Email address: userxyz@domain.au) and is configured to deliver the mail from
the POP3 mailbox to the corresponding user's mailbox on the Exchange server, the server will accept the mail provided it has an address
space configured in its recipient policy which matches the Email domain of the POP3 acccount. In this case, @domain.au.

OK, now what happens to this mail? Exchange will deliver the downloaded mail to the user's mailbox provided that there is an exact match
for the user's POP3 domain name in the Exchange recipient policy otherwise it will not. Exchange will not "make this mail available to the
user" unless there is an exact match between the one of the user's SMTP aliases and the email recipient to which the POP3 mail is
addressed. The mail is in the mailbox (as you have observed using the Exchange System Manager) but the mail is not "delivered." The
user's SMTP alias which exactly matches the user's POP3 mail account Email address is normally set as the primary SMTP alias which then
becomes the reply to addres for outbound mail from this user.

The Exchange Recipient Update Service (RUS) stamps the users' accounts in the Active Directory with the automatically generated SMTP
aliases derived from the SMTP address spaces in the recipient policy plus the users' logon names. So if this user's logon name is user, the
automatically generated primary SMTP address for the user will be user@domain.au, not userxyz@domain.au. The mail downloaded from
the POP3 server by the connector was delivered to the mailbox but is held there because there is no user in the AD with the correct SMTP
mail address to receive it. Fix this problem by adding an SMTP address, set as primary, which exactly matches the user's POP3 Email
address, in the user's account properties | Email Addresses Tab.

I have installed SBS 2003 and am using the pop3 connector
to download emails from a number of external pop3
accounts. The emails are downloaded and removed from the
external hosted server every 15 minutes as specified. The
downloaded emails appear in the respective mailboxes for
the users. At least the number of emails in the mailbox
appears correct. All clients are using OL2003 for email
and when they log in and send/receive etc NO emails are
downloaded from the SBS server. A solution to create a
new profile in OL2003 with only the Exchange account was
suggested but this does not work. I would be very
grateful for any help as I have to get this fixed ASAP
