Well, that depends what you want to do. If you have switched on Message Tracking, you can get the Message-ID from this. The tracking files are simply tab-deilmited files so can be easily extracted into a database/loaded into Excel, etc. There is almost certainly software out there that does that for you. But I don't know of it. ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Ahmad Sent: 14 February 2008 09:03 To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Outgoing mails Auto Reference Number any software for this purpose ??
