Hi,

We need to know the user who sent us a message from a shared exchange account :
 
TESTE (test@xpto.com) is the account name of our team member mail account. There are 20 people that have access to it and can send e-mails from it. When someone receive a mail from this team mail account, the sender´s identification name is always from "TESTE <test@xpto.com>", but as the sender´s usually signs at the end of the message the name, no big deal. The problem is when the sender (user) intentionally don´t sign the message, and the recipient  can´t know who sent it (there are 20 possibilities).  

As all of the 20 people that could send messages from test@xpto.com have to authenticate to mapi, maybe it will be possible to check which user sent it on some logs....we just need to know who was the user.

Below is the e-mail header we received from the unknow user (we got it from MS Outlook message proprieties):

Received: from SDC1RI00EVS03.xpto.local ([fe80::39cb:6a9d:fbef:aee3]) by
 SDC1RI00ECH01.xpto.local ([110.12.0.101]) with mapi; Mon, 14 Mar 2011 15:02:07

I think it allready is Exchange 2010, but not short. If not, it will be 2007.

I appreciate if you could give the solution for both versions, if possible.

Thanks,

There is no natively logging for mapi sessions. The only way i can think of is if the email is sent via owa and on CAS server you have NCSA logging enabled for IIS server. That can record the client IP again it will only give you the client IP but not the actual user.

We will try that!

I was thinking that if we have the MAPI Message ID "Message-ID: <51CD5B63E71D6249A3A72237A954E84982DA8981B8@SDC1RI00EVS03.xpto.local>" and the sender user still to have it in is inbox folder,we could seek on the server database in wich user account  the message is...ist that possible?

Sorry, I wanna say "iuser still to have it in his sent items folder".   In MS Outlook 07, when we send a mail from a secondary exchange account (as test@xpto.com) the mail stays on the "sent items" of primary account (usually the personal one).

That would be manually checking each one sent items folder and what if the message is hard deleted
