Maybe Perfmon.. Run it on both your server and your workstation for a
few hours each side of that "first" email. On the workstation look at
memory, cpu and network. On the server look at the same but throw in
physicaldisk/current queue length and MSExchangeIS RPC packets (I
think). Basically you want to see if anything is maxing out, the RPC
stats will show you if your server has enough threads available, memory,
disk and CPU are pretty much self explanatory. As usual check both
system and application logs for any signs of DNS or domain issues, it's
all related, if you have DNS or domain security issues and so forth
you'll see Exchange problems also.
With 15 people in the company are you running Exchange on your DC? If
so your server may simply be breathing a little hard or your seeing
symptoms of an uglier issue like HW failure or Domain issues. I run
over 6,000 users on 3 Exchange servers (beefy servers) and it doesn't
happen all that much, but we do see a lag every now and then, specially
when someone sends out one of those 20MB attachments.
Hope this helps some,

I am on the same LAN and the Exchange server, we only have 15 people in
our company. I think it happens regardless of time its just the first
email. I click send and it sits there on my screen and then sent about
10 seconds later. If I send another email right then and there is goes
right through. I have a 10 Mb Internet connection and the Lan is at 100
or 1000 Mb.
Thanks Bruce Rose

Where are you seeing it being held up at, the client, outbound queue,
other end? If your a typical business remember that first thing in the
morning is the busiest time for your Exchange servers, thats when
everyone is logging in and opening thier mailbox for the first time of
the day. Large mailboxes take a few seconds to open and put a heavy
(temporary) load on your servers, you may simply be seeing user
contention.
What type of connection do you have for outbound traffic? Older
connections like ISDN will disconnect during off-hours and do take a
minute or so to reconnect in the morning. It's possible that your
seeing an issue with your internet connection dropping during off-hours.
Just some thoughts, Maybe describe your setup a little for us (servers,
number of users, connection, etc...) and we might come up with some
better answers.

Subject: [ExchangeList] First Email of the morning
When I send the first email every morning it take is like 10 seconds
before it is sent, all of the rest of the emails I send through out the
day send right out but the first one just sits there for 10 -15 seconds
and then is sent. Do not see any events on the Exchange server. I have
Exchange 2003 non Enterprise SP2 on windows 2003 Domain Controller. Yep
I know should not be on a domain controller but it was like that before
I got here. I will be putting in a new Server for the Exchange and
migrate to it.
Thanks Bruce Rose
