Hello, Setup setup: Windows 2003 domain/AD server (single domain) with Microsoft exchange installed. Problem: Just recently, when a domain client PC uses Outlook to send an email addressed to a "Group" of recipients, the only recipients who receive it are those that are not in the domain. Does anyone have any thoughts as to why this might be? Thanks, Kevin

So you have a DL which internal and external contacts. But only the external contacts are getting the emails? What does message tracking say?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi Kevin, Does sender receive any NDR? If the internal members of DL check email messages in OWA, can they receive the email message in question? Fiona Liao TechNet Community Support

Hi, The sender and recipient receive no notifications but the sent email is on the Server and readable through OWA. These same recipients do receive email from outside of the domain correctly but not from within. How can I view the message tracking info? Kevin
