I know I can not set the same proxy address on multiple user objects, in this case, contacts. Our baseball club wants to use Distribution Lists to be able to send an e-mail to team members. There are a few fathers that play, while their kid plays in another team. The e-mail address of the father is used as the e-mail address of the kid. resulting in a different contact with the same e-mail address. I would say this should be possible. It currently is working on a Linux server. How? Best regards.

Not sure I understand what you want to do here.lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com

So, basically you want two contacts with the same target email address, but with different display info? If that's the case then I think you can do this by creating two contacts that have the same targetAddress attribute value, but with different proxyAddresses values. The targetAddress attribute value is the one used by Exchange for routing purposes. It would look something like this: Contact 1 DisplayName = Joe Wilson proxyAddresses = SMTP:joe.wilson@MyExchangeSMTPDomain.com targetAddress = SMTP:FamilyWilson@gmail.com Contact 2 DisplayName = Bob Wilson proxyAddresses = SMTP:bob.wilson@MyExchangeSMTPDomain.com targetAddress = SMTP:FamilyWilson@gmail.com Tony

For my understanding, do you want use one email address to send to multiple mailbox? What you need to do is only to create a Query-based Distribute group for those mailbox. And then you can set SMTP address for this group.
