Sounds like you need to set your Receive Connector Authentication Mechanism setting to ExternalAuthoritative.
Set-Receiveconnector "RC_Name" -AuthMechanism TLS,ExternalAuthoritative See the following information: http://technet.microsoft.com/en-us/library/aa996395.aspx ExternalAuthoritative The connection is considered externally secured by using a security mechanism that is external to Exchange. The connection may be an Internet Protocol security (IPsec) association or a virtual private network (VPN). Alternatively, the servers may reside in a trusted physically controlled network. The ExternalAuthoritative authentication method requires the ExchangeServers permission group. This combination of authentication method and security group permits the resolution of anonymous sender e-mail addresses for messages that are received through this connector. This replaces the Resolve anonymous senders function in Exchange Server 2003.

However, anonymous smtp mail from e2k to e2k7 such as script notifications etc come through to Outlook showing with the smtp address in the display name rather than the Display Name. i.e. "FirstName LastName" I have checked the Global settings - Internet Message format for that Domain and made sure that the "Preserve Senders Display Name on Messages" is checked which it is. Global settings Internet message formats Properties of relevant domain Advanced Does anyone have any other suggestions of others things to look for? Regards John Stevens Messaging Consultant
