Dear Sir/ Madam. System: Exchange 2010 As we know, we can possible to set "Mailtips" of "warning external recipient". it means, warning before sending external recipient to our people. but, I want to set "specific domain or specific external recipient" not every external recipient. **************************************************************************** example) specific domain: abc.com someone try to email to 123@abc.com --> in that case outlook 2010 shows up warning. but someone try to email to other external domain/ recipient --> in that case outlook2010 does not show up warning. ********************************************************************************************* How to set those configuration by Mailtips? is it possible? E.O.D.

Hi, a mailtip feature is intented to be used where the sender and the receiver belong to the same exchange organization. For instance one of the tip is to avoid sending emails to a user whose emailbox is full. Of course, such a control imply the sender and reveicer belong to the same organization and the email system "suggests" the sender what to do before any communication sender/receiver is attempted. As far as I know, it is possible to alert the sender when he is attempting to send an email outside the organization, regardless the external domain the receiver belongs to. In that case the sender gets a tip messsage like: "the following recipient is outside your organization"

AFAIK MailTips are not configurable. You can turn off the one in question: Set-OrganizationConfig -MailTipsExternalRecipientsTipsEnabled $False but I don't think there's any practical way to modify how it works. Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi, You can set mailtips for the specific external recipient, e.g. Set-MailContact "contact name" -MailTip "information" Details, please see: Configure Custom MailTips for Recipients http://technet.microsoft.com/en-us/library/dd638199.aspx And if you don't want to set mailtips for every external recipient, you can disable the External Recipients MailTip: Configure Organizational Settings for MailTips http://technet.microsoft.com/en-us/library/dd638109.aspx Frank Wang TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.

It won't work for a whole external domain, I understood this was the need Indeed you can use mail contact as suggested, but you would need to create all of them in your organization, be aware of that is you are required to implement for a lot of external recipients. Also, usually emaployees have many different email addresses like: name.surname@abc.com (primary smtp) name@abc.com surname@abc.com first_letter_name.surname@abc.com etc. etc. If you promise you created a tip for a specific external user (contact name.surname@abc.com), someone that will send an email to surname@abc.com could complain because he accidentally sent it without receiving any warning. I think it's something you need to be aware of. Hope it helps

Can I use other way by trasport rule or moderate rule or delayed email function?
