on a new Unity 7 Deployment with Exchange 2007 - Used COBRAS to migrate from Unity 4.0.5 running on an old ICS7750 - New Domain on the 2007 Server. This is a Unified Messaging deployment.
When the caller leaves a VM, the MWI lights on the users phone, but the instant Outlook receives the message, the MWI light goes off. The message is not marked as read, and there are no rules directing it to another folder. Even if you right click the message and mark as unread, nothing changes and the MWI light does not come on.
Does anybody have experience with this issue?
What happens if Outlook is not running on the user's desktop? Does the MWI still get turned off in that scenario? If so, then something in Outlook is marking the message as read. Maybe they have the preview pane loaded? First, see if it is coming from the client (i.e. Outlook).
