Hello Friends; I Have Exchange 2010 Server running in Windows Server 2008. My problem are as follows: - Out Of Office Messages are only sent internally and NOT externally . - After researching i realised that Out of Office messages are being rejected due to the null <> used as sender . In Exchange 2010/2007 Microsoft has changed the behavior of automatic server based notifications, especially “Out of Office” replies which should be sent with a blank sender This means that the HUB Server in your organization replaces the senders name with a blank one while transferring it to the internet. *Facts : * - I have no firewall installed for incoming/outgoing emails hence you can overlook this. - Exchange Connectivity test results are ok . - If you create an Open Relay Send connector the Out Of Office Message is sent to external clients but we receive very many NDrs since most Smart Hosts reject messages from a n Open Relay Send Connector. - The Companies Smart Host is smtpout.accesskenya.com - CMD Shell Results : All our settings are correctly configured . Below are the CMD Shell Results : *NonMimeCharacterSet : iso-8859-1 AllowedOOFType : External AutoReplyEnabled : True AutoForwardEnabled : True DeliveryReportEnabled : True NDREnabled : True MeetingForwardNotificationEnabled : False ContentType : MimeHtmlText DisplaySenderName : True TNEFEnabled :* Our CMD Results indicate that the message is configured . Is there anyone who can help with this ?
