Do you see the emails in your message tracking logs when you send them?[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

If you are running in cached mode you are using the offline address book. OAB updates every 24 hours by default. Then your outlook client would have to download the updates. You can force the update of the OAB by right clicking on it. Then through send/receive all through Outlook there is an option to download the Global Address Book. When was the changes made to this group?Chris Morgan

Hi, What’s the scope of the mail-enable group? Are you using Global mail-enable group? Have you recently installed or removed a domain controller or global catalog within the domain? And what’s the topology of your organization? Have the message you sent to the group stalled in the delivery queue on the exchange server?
