Hi,

I have Exchange 2000 setup in my organization. My ISP
still hosts my mail. I am using Exchange to download e-
mail via a POP3 connector which in turns delivers the
messages to each user's mailbox. (User's are Exchange
user's connected from Outlook)

Problem: There are random times whereby a user may not
receive some External e-mail. For some reason Exchange
would not route the messages to the user's mailbox after
downloading from the ISP.

Here is an example.
-I will send an e-mail from an external address such as
hotmail
-I force a download on the pop3 connector on the Exchange
server
-I check that user's mailbox on the server and it is not
there
-I check Outlook on the client and the message is not
there either
WHERE DID IT GO? Can anyone please assist with
troubleshooting steps.
I know that this is not the ISP because of the following:
-I setup Outlook on the client to connect via a POP3
account
-I will send an e-mail from an external address such as
hotmail
-I check for the message and it appears fine.

PLEASE HELP OR COMMENT AS THIS IS VERY FRUSTRATING.

Thanks.
