Hi folks. I have a Unity 5.0(1) server that is partnered to an Exchange 2003 message store. There is also a new Exchange 2007 server in the same organization on the same domain, AD site, and subnet. Any user that is homed on the Exchange 2003 server is doing well. Any user on the Exchange 2007 however gets a message retrieving their voicemail that "The messaging server is offline". No voicemail gets into their Exchange 2007 inbox; essentially the Unity UMR is active for Exchange 2007. In Outlook, an Exchange 2003 users can send email to the Exchange 2007 users and reverse. This happens with users moved from Exchange 2003 and users newly created on the Exchange 2007 server. When I look at the Profile of the subscriber account in SA, it shows them as being on the Exchange 2007 server as it should. The Exchange 2007 server is clustered. Anything I should be looking for? Thanx!
