Dear all, I have a outlook 2007 distribution list that have over 1000 Email address. When I send the email to this distribution list,the user aaa@xxx.com can receive the email. Actually, I can not find this user(aaa@xxx.com) in this distribution list. I delete the email cache in the PC, but this user still can receive the email. I use delivery report to track this email, I can find this email from the "To:" field. what happen? thank you john

John, There is a sure chance of 'forward' email is set for any other user in the list.Regards from www.windowsadmin.info | www.blog.windowsadmin.info

You need to run a query to find the forwarding rules which can be done on the server end mailbox properties, mailflow settings, delivery options which you can just use ldap to query the altrecipient attribute. However if the client has a rule than you can use powershell to query the inbox rules. http://www.onesimplescript.com/2011/11/auditing-exchange-inbox-rules.htmlJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi John, Please verify from the user aaa@xxx.com Inbox to see if the email message is sent directly from you to the DL. Also check the message header information. Hope it is helpful.Fiona Liao TechNet Community Support
