When we create a new email message in Outlook 2003 (user 1) and send it to a
certain recipient (user 2). That person (user 2) does not receive it, but
when the other person (user 2) sends an email to (user 1) it is received.
Now when (user 1) replies to that message it is then received by (user 2).
User 2 never gets an email message that was created by user 1. As far as we
know and have tested all other emails that go out from user 1 do get recevied.
I've checked with the ISP and tested the web interface and that works. Just
not in outlook.
So user1 sends an e-mail and it does show up in user2's mailbox as can
be seen by using the webmail interface to user2's account.
Is this a POP or IMAP account for user2?
If POP, is user2's e-mail client configured to delete or leave messages
on the server after retrieving them? The default is to delete messages
after they have been retrieved so setup user2's e-mail client to NOT
"leave messages on server". After seeing a test e-mail show up in
user2's mailbox (by using the webmail interface to it), poll with the
e-mail client. If that e-mail client is receiving the e-mail, it should
then delete it and you will see it disappear from the mailbox (by using
the webmail interface). If the e-mail disappears from the mailbox,
users *is* retrieving e-mails and the problem is on their host.
If the test e-mail remains in the mailbox (you see it there using the
webmail interface after the e-mail client did a mail poll) then perhaps
the e-mail client is being told there are no messages in the mailbox.
Is this user2 perhaps using a Gmail account? The client requests a list
of items in the mailbox. If the server returns a null list, the client
is being told there are no items in the mailbox. That means the client
has nothing to download so it ends the mail session. Gmail is known to
****up its Inbox. You can see new items sitting there when using the
webmail interface but the POP client is getting back a null list from
Gmail saying there is nothing there. Removing all items from Gmail's
Inbox sometimes fixes this sync problem.
You could enable the troubleshooting logging in the e-mail client. With
a known *new* item in the mailbox, poll that account by the client.
Then look in the log to see what the client got back from the LIST
command. If a non-null list is returned, the client usually follows
with a UIDL command (to get the unique IDs of the mailbox items rather
than rely on their relative index number). You can then see if the
server is telling the client if there are items in the mailbox (LIST
will list all items since "new" is only defined in the client, not by
the server).
