Exchnage 2010 Email Queue

Hi ,

My organisation Is sending large attachment and I could say  10 emails at the same time each email 15 to 20 MB, when I monitor the Queue in the Queue Viewer there is a queue called the same as our smart host, each email will take 5 min to process and I  can only  see two email will be active at the same time.
Is the behaviour normal  with large emails , is there a way we can have more emails active instead just 2 at the time

Are you sending those emails on the same message or separate messages?
If on the same message, then Exchange will just send them all in one go to the smart host.
If they are sent on individual messages then they will be processed individually. However it should not take anything like 5 minutes to go, unless you are on a very slow upload connection.
Therefore changing the configuration isn't going to achieve anything, because the behaviour you are seeing isn't normal.

If you are on a very slow connection, then configuration change will do nothing for you either, because the bandwidth is still the same.

Hi Simon

The attachment  are sent in different emails probably one message will be emailed to 2 users ,  the emails are generated automatically and in one go they will generate 10 emails each email will be more  then 15MB, our upload speed is normally 8 Mbps,
When I monitor the Queue , sometimes under status I see the email being active and sometimes just 1 email is active ,
I have attached screenshot , as an example ,  one of them has 2 emails and is taking 5 min to process

I think you are simply expecting too much from Exchange.
It has to process the emails, encode them to the correct format for transmission. Going by your queues you have a lot of large emails there which it needs to process.
Therefore some delay I would expect to see, no matter the speed of the internet connection. 10mb emails are NOT normal - most emails will be significantly less than that.

Do ensure that any file based AV software is not scanning the Exchange directory structure, as that can cause delays. However I don't think you will get Exchange to send email out any quicker.
