Tracking outbound messages in Exchange 2010

Hello experts,

We have Exchange 2010 SP1. It uses an SMTP relay server to send messages through. That server allows us to send 300 messages per day. We usually send about 70 messages of them.

Suddenly today, 300 messages were sent so we can't send anymore messages. I have increased the quota to 450 to solve this. But in less than an hour, those 150 messages were used !

I think there is some computer infected with a virus inside the network.

The question: How to track which users have sent messages through exchange in the last 24 hours?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can use the 'Tracking Log Explorer' from Exchange Management Console -> Toolbox

Just set SEND as the EventID and the timeframe required.
