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
I would run Exchange System Manager on one of the Unity servers and use message tracking to see where the message gets stuck. Also check the following path depending on your drive config - \commserver\unitymta and \commserver\unitymta\failed. If you see the messages in the unitymta folder, Unity thinks Exchange is down - would also see application event log errors though. You can also try restarting the AvUMRSynchsvr service if you see messages in \commserver\unitymta. Messages left in \commserver\unitymta\failed indicate a different problem, most often with user's inbox. If you find the message stuck in one of the Exchange servers, check that the services are started like SMTP, Exchange MTA Stacks, and Exchange Routing Engine.
Ginger, thanks for your reply. I have tracked the message. I also have an smtp smart host so that smtp notifications are sent to the customers domain. According to message tracking, any message i send from server 3 to server 5 or any combination is being sent to this smart host...weird??. Can't explain that one.
Hi Ginger, as a test I took off the smart host from the sending server and the message gets delivered fine to the second server.However I need the smart host for external notification- there must be a way of stopping messages from within my domain going to the customers domain?
Hi Ginger (aka 'top man') that resolved my issue - thanks again for your help, much appreciated.
I had created a smart host on the smtp virtual server - external notifications to customers domain was working fine but for some reason my internal messages from unity server A to unity server B were also going down that route. Now I deleted that and instead created a connector and put the smart host in there - now works fine..best wishes, Jag.
