Outlook 2003 POP/SMTP Exchange 2007

[Barton]

We setup a new Exchange 2007 server. The decision was made to connect a
remote 4 person office using POP3. 1 Outlook 2003 and 3 Outlook 2007.

3 are able to send/receive without error but one of the Outlook 2003 users
cannot send email. The Test Account Settings completes successfully and the
test message is received into the inbox. If you create a new message, the
sending message dialog stays up until you hit cancel and the message does not
get sent.

I saw on one website there was a patch in order to send using port 587 and
Outlook 2003. Clicking on the link took me to a login page for which I do not
have access.

Is there a patch that needs to be applied to Outlook 2003 in order to send
through port 587?

No, there is no such path needed as you can specify the port to be used in
your account settings.

What is your exact setup?
The collect POP3 mail via Exchange or via Outlook?
Are they sending via the SMTP server of the POP3 account or via the Exchange
server?
If via the SMTP server of their POP3 account verify that authentication is
enabled in the account settings and that the proper ports are opened on the
corporate firewall. It would be a better choice to send the emails via the
local Exchange server.

Exact setup - Exchange 2007 server at main office all mail sent and received
through Exchange server. All users in main office connect directly to
Exchange server.

Second small office (4 users) retrieving email from the Exchange 2007 server
using POP3 (port 995) and sending email through the Exchange 2007 server
using SMTP (port 587). One of the 4 users is unable to send email. As stated,
from this user's Outlook 2003, the test account settings function does send
the Outlook test email and the email is received back into the users inbox.
He cannot send emails he creates.

Verify that at least Office 2003 Service Pack 2 is installed on that client
but better would be Service Pack 3.
Also verify the firewall settings on the client.
If there is a virus scanner installed that integrates with Outlook, disable
this integration and try again.

Instead of using POP3 consider using Outlook Anywhere (RPC over HTTP). This
way you can keep all the Exchange functionality and have centralized
backups.

After installing Office 2003 Service Pack 3 emails can be sent and received.
Now a new problem. I am told read receipts are sent when Outlook receives the
emails but the emails have not been read by the user. They are marked as
unread in Outlook.

I read in another forum that this is by design of the Exchange server.

Is it true that Exchange considers email as read once it is received using a
POP3 connection?
