Hi, we hve 3 unity 5.x server networked together, onbox storage. All 3 are part of same exchange organisation. I can locate a user from one unity server to another using the networking and send a message but it never arrives at the remote users mailbox. I tried accessing this with web mail sending from one mailbox to another and to a different server it also fails. Same server is fine, any ideas, looks like an exchange issue rather than Unity??...Jag
On the SMTP connector, Address Space tab, is the Address specified as *? If so, at a time you can safely test, replace the * with the customer's domain name and put the smart host back in. If you have multiple SMTP connectors, you will need to adjust the cost so mail flow works the way you want - here are two good articles on that - http://www.msexchange.org/tutorials/Using_SMTP_Connector_Internally.html and this one - http://support.microsoft.com/kb/294736
I know from experience working with the Unity Bridge voice connector, which uses a smart host can, if coded incorrectly, screw up mail flow for an organization.
