emails sent but not received

[Surfer01]

My company is using Outlook 2007. I routinely get complaints from employees
saying they are not getting emails sent by other office employees. For
example, when I send an email, it clears out of my outbox and moves to my
sent box. However, the receiver does not receive it for several hours. I
have checked with our email host who shows no problems on their end. Any
ideas?

Thanks in advance

You don't mention WHAT mail server that you are using. If SMTP, why not
look at the Received headers in the received e-mail. You can then see
when the sender's mail host actually transmitted the e-mail, how long it
remained in any intervening mail hosts, and when the recieving mail host
got it. If the recipient isn't seeing the message for hours after their
mail host showed it already received the message then the problem is
with internal delivery with the recipient's mail host to deposit the
e-mail into that recipient's mailbox (so it available to the e-mail
client).

Are these all email sent inside the same company that have problems, or are
the recpients outside the company?

If outside (internet), there is no guarantee that email is instant. It can
take minutes, hours, and sometimes days to get through. It all depends on how
many servers are involved, etc.

If this is internal mail, is Exchange in use? If this is the case, turn on
message tracking or post in the Exchange newsgroup.

Also, if the recipients aren't receiving their email, are the senders getting
NDR's (non delivery reports) back? Have the recipients checked their junk
mail folders? Do they have rules in place?

What type of account?

The emails we've noticed today are all internal, i.e., all running through
GoDaddy, our email host. We're using Outlook 2007, not Exchange. Our
outgoing setting is smtpout.secureserver.net. Since we're using Godaddy as
our outgoing server, our ISP says it's not their problem.

Any ideas?

No bounce messages are received by the sender.

Thanks, I've submitted the email headers to our ISP to see what they say.

That would only might help if your ISP also your ESP (e-mail service
provider).

If your company is using its own Exchange server, your ISP
can't help. You didn't mention what type of e-mail accounts the
"company" uses.

Scanning your in and outgoing emails by an AV by any chance

Yes we are. Using Symantec Endpoint installed on the server with clients
installed on local computers. Using version 11.0.1000.1375.

Disable the email scanning feature. This is what is most probably what is causing
this issue. You might need to uninstall the AV especially Symantec and then
re-install it without the email integration (scanning) for it to become effective.

Thanks, Peter. Scary thought to turn off the email scan but I've heard this
before from other sources. Will check into this further. Are there any
settings I should set in Outlook 2007 or endpoint to check the attachment
upon opening?

That's the point. As long as your on-access scanner is still installed, it
will detect any infection when you open the attachment. Of course, you
wouldn't even open it if you didn't recognize the sender and you didn't
explicitly request the attachment. If it's unsolicited, no matter who sent
it, just delete the message without opening it.
